This booklet is issued by the Forests Commission of Victoria to aid bush walkers, boy scouts and all those other members of the community who would be interested to probe a little deeper than just to accept our forest trees as being either “ gums ”, “ wattles ” or “ the bush It is not a key to the separation of the many and varied species of eucalypts and acacias, but it does set out the simple elements of botanical significance and how to recognize them. Armed with such knowledge and fortified by practice our reader can refer with confidence to more advanced works on the subject.

The forests of Victoria comprise a striking majority of species of Eucalyptus. With the exception of the wattles (Acacia), she-oaks (Gasuarina) and native pines (Callitris), other plant families which include trees are poorly represented. In the higher rainfall areas, blackwood (Acacia melanoxylon), myrtle beech (Nothofagus cunninghamii), musk, hazel and blanket wood constitute the gully flora and, with the exception of myrtle beech, are widely represented in the shrubby undergrowth.

The portion dealing with forest regions and types and the occurrence of the Victorian eucalypts has been taken from “ Handbook of Forestry in Victoria ”, 1957, by K. V. M. Ferguson, M.A., B.Sc.; the diagrams of eucalypt buds and fruits from “ Illustrations of Buds and Fruits of Eucalyptus Species ”, Forestry and Timber Bureau, Commonwealth of Australia, Leaflet No. 63, 1954,1 and those depicting Acacia, Casuarina and Callitris from “ The Forest Flora of New South Wales ”, 1907, by J. H. Maiden. Due acknowledgement in each case is hereby given accordingly.

The first species of Eucalyptus known to science was collected by David Nelson, assistant botanist on Cook’s Third Voyage (1776-9). It was described by L’Heritier in 1788 and named Eucalyptus obliqua, L’Herit., the generic name arising from the Greek eu= well, kalyptos = covered, alluding to the cap or lid which covers the stamens in the bud. The origin of the name Acacia is from the Greek akakia, a name given to some prickly plants growing in Egypt. Casuarina is derived from the Latin Casuarius, likening the drooping branchlets to the feathers of the cassowary, and Callitris comes from the Greek kallos = beautiful, treis = three, because of the symmetrical arrangement of the leaves.

The question often arises as to why a system of botanical nomenclature is used for trees. A generic name and its associated specific name are essential for scientific purposes because mistaken reference is thereby avoided. Vernacular or common names sometimes create confusion since different vernacular names are frequently given to the same tree, for example, Eucalyptus leucoxylon is commonly called white ironbark or yellow gum in Victoria, and blue gum in South Australia.


Owing to the close relationship of some species and the great variability of the parts of the plants, Eucalyptus is a difficult genus to classify. Nevertheless, many species exhibit distinct characters which enable their identity to be readily determined. As a means of preliminary identification in the field, a knowledge of bark, leaf, bud and fruit characters will prove most useful to the beginner.


Victorian eucalypts may be grouped on broad lines in the following bark classifications:—

(a)    Ironbark:

Very hard ; deeply furrowed near base of tree ; bark grey to black in colour, sometimes showing red at base of furrow.


Red Ironbark—E. sideroxylon Silvertop—E. sieberiana

(b)    Gum or Smooth-bark:

Usually smooth and slaty-grey to white, but may be rough and dark at butt of tree. Bark is shed seasonally either in long strips or in large plates. At certain seasons bark may be tinged pale-green (E. viminalis), red (£. rubida) or dull yellow.

Species :

Manna Gum—E. viminalis

Candle-bark Gum—E. rubida

Yellow Gum—E. leucoxylon

Red Gum—E. camaldulensis

Blue Gum—E. globulus var. bicostata

Shining Gum—E. nitens

Snow Gum—E. pauciflora

(c)    Peppermint :

Grey in colour ; soft but not fibrous ; structure reveals definite trellis formation.

Species :

Common Peppermint—E. radiata Broad-leaf Peppermint—E. dives Mountain Ash—E. regnans

(d)    Box:

Firm to hard ; lacks characteristic structure ; rarely ridged or furrowed except at butt of old trees. Yellowish (E. melliodora) to dark-grey.


Yellow Box—E. melliodora

Grey Box—E. hemiphloia

Red Box—£. polyanthemos

Black Box—E. largiflorens

Gippsland or Coast Grey Box—E. bosistoana

(e)    Stringy bark:

Soft and fibrous with stringy structure ; stringy fibre may be short as in Messmate, or very long. Brown in colour.


Messmate—£. obliqua Red Stringybark—E. macrorrhyncha Brown Stringybark—E. baxteri White Stringybark—E. scabra Yellow Stringybark—E. muelleriana Alpine Ash—E. delegatensis


Another useful means of identification is available from the appearance of the leaves. The mature and juvenile leaves of the same species are often quite dissimilar. Mature leaves can be divided into a number of different categories according to the species concerned. The most common shapes are broad-lanceolate, narrow-lanceolate, oblique,

Heart-shaped E. leucoxylon

Leaves Opposite Stem-clasping E. globulus var. bicostata

falcate, and ovate. Colour also sometimes assists in identification ; greyish-green (E. polyanthemos), bluish (E. fruticetorum), pale-green (E. sideroxylon), dark-green (E. viridis). The arrangement of the veins is occasionally of importance ; namely, divergent parallel veins (E. botryoides), main veins parallel longitudinally (E. pauciflora).

The juvenile foliage of seedlings, or of shoots which develop on a tree as a result of damage can also assist in identification. The arrangement, colour, and shape of young leaves is often quite different from the foliage of the adult tree, and the shape of the stem is sometimes equally dissimilar. Some of the more common features of juvenile leaves are provided by the following examples :—Arrangement of the foliage ; leaves opposite and without stalks (sessile), sometimes stem-clasping E. globulus var. bicostata. Colour; leaves bluish-grey (glaucous), E. goniocalyx. Shape; leaves very broad and shortly-pointed (ovate) E. dives; long and narrow (linear-lanceolate) E. radiata ; rounded (orbicular) E. rubida ; heart-shaped (cordate) E. leucoxylon. Shape of the stem ; square, E. nitens, E. globulus var. bicostata, and E. goniocalyx.

Buds and Fruits

In a publication such as this, it is quite impossible to present a comprehensive picture of the extraordinary variability exhibited by this genus as a whole. As an example, however, the illustrations of buds and fruits depicted at natural size herein convey some idea of the extreme differences which occur between some species.

Those diagrams appearing on pages 12 and 13 illustrate the size-range of buds and of fruits; their varying shapes and the ornamentation of species having widely scattered habitats in Australia. On pages 14 and 15, the examples shown belong to some of the most important species occurring in Victoria. It can be seen that while these particular species do not show the great differences of those displayed on pages 12 and 13 they are nevertheless by no means morphologically similar.

Very large buds and fruits are depicted on page 12 and much smaller examples appear on page 13. Eucalypt fruits (capsules) consist of three main parts ; the calyx tube, the rim which is found at the top of the calyx tube, and the valves that open to permit the seeds to escape. The calyx tube forms the main body of the capsule ; sometimes it is quite smooth (E. delegatensis), ribbed (E. angulosa), or variously ornamentated (E. pyriformis). The rim may be flattened (E. muelleriana), rising (E. macrorrhyncha), or falling (E. sideroxylon). The valves may be strongly exserted (E. cornuta, E. camaldulensis), sunken (E. sieberiana, E. obliqua), level with the top of the calyx tube or nearly so (E. scabra, E. nitens).

The buds of some species have stalks (pedicels) joined to a common stem (peduncle), (E. leucoxylon), others c!o not (E. cornuta). Occasionally they are grouped in threes (E. viminalis). A bud is composed of two parts ; the lower part is known as the calyx tube, and

the upper part as the lid or operculum which is shed as the flower opens. As is the case with capsules, the buds vary greatly in size and form. The cap is usually shorter than the calyx tube (E. hemiphloia), sometimes it is much longer (£. cornuta), or sometimes it is of about equal length (E. goniocalyx). It may be pointed (E. camaldulensis, E. macrorrhyncha), rounded (E. delegatensis, E. papuana), or ribbed (E. pyriformis).


The features separating the genera Acacia, Casuarina and Callitris are quite distinct but, as with Eucalyptus, difficulty can be experienced in identifying individual species.

Some species of the genus Acacia have bipinnate leaves, for example A. dealbata (Silver Wattle), and A. mearnsii syn. mollissima (Black Wattle), or after the seedling stage, a leaf-like structure which is really a flattened leaf stalk (phyllode), e.g., A. pycnantha (Golden Wattle) and A. melanoxylon (Blackwood). The seeds are contained in a pod (legume).

The foliage of Casuarina is represented by whorled teeth united into sheaths surrounding the summit of each joint (node) of the branchlet, the number of teeth being within a certain range according to the species concerned ; for example, usually nine to twelve in the case of C. stricta (Drooping Sheoke), nine or ten C. cristata syn. lepidophloia (Belar), and six to eight C. suberosa (Black Sheoke). The cones which hold the seeds vary in size and shape ; those of C. stricta are sometimes as large as 21 inches long and 1J inches broad with strongly projecting valves from which the seeds escape ; those of C. suberosa are much smaller, usually cylindrical in shape and about i inch broad ; and those of C. luehmannii (Buloke) are quite flattened in comparison, consisting of only two or three rows of valves.

The various species of the genus Callitris are usually identified from the nature of the cones. The seedling leaves are mainly in whorls of three completely free but, with the exception of the tip, they soon become adherent (decurrent) to the stem. Victorian species of Callitris have cones with six woody valves, half of them smaller than the others, and opening outwards when mature. Some species exhibit a simple three-sided swelling (columella) rising from the inside of the base of the cone such as C. hugelii syn. glauca (White Cypress Pine), and C. preissii ssp. murrayensis syn. propinqua (Slender Cypress Pine); others show a threc-lobed columella, for example C. endlicheri syn! calcarata (Red Cypress Pine) and C. rhomboidea syn. tasmanica (Oyster Bay Pine); and the cones of C. preissii ssp. verrucosa syn. verrucosa (Scrub Pine) which is usually a stunted multi-stemmed tree or shrub, are densely covered with small swellings (tubercules) The columella is generally short and thick.

The Victorian indigenous forests generally are of a sclerophyllous type and their composition is characterized by a very marked predominance of species of the genus Eucalyptus, members of other genera usually being relegated to the understorey. In relation to the comparatively small area of the State (87,884 square miles) there is considerable variation in forest composition, quality and distribution due to a diversity of locality factors—e.g., average annual rainfall varies from under 10 inches to over 70 inches ; elevations from sea level to 6,500 feet; topography from flat coastal and inland plains to rugged and rocky mountain terrain ; temperatures from equable and mild along the coast to extreme in the north-west; soils from shallow, barren, dry and rocky to deep, moist, fertile volcanic loams.

The general climate is a temperate winter and early spring (July-October) rainfall type. Late spring and summer rains are erratic. Regional climate is influenced to a marked degree by the Dividing Range which traverses the State from east to west at a distance of 60-90 miles from the southern coastline, rising to a maximum height of 6,509 feet at Mount Bogong. This intercepts the moist, southerly winds from the ocean, with the result that annual rainfall north of the Divide seldom exceeds 25 inches. At elevations below about 2,500 feet falls of snow are few and light, but occasional severe frosts are experienced inland. Snow at the higher altitudes may lie on the ground for up to six months. The best forests are in regions of over 40 inches rainfall; the 25 in.-40 in. belt also carries good commercial forests ; where rainfall is under 25 inches, forests are more open and of slow growth.

Winter temperatures, except in the highlands, vary little throughout the State, but there are considerable regional differences in summer temperatures which are generally high. Average daily maximum midsummer temperature in coastal, Gippsland and highland regions is considerably lower than north of the Dividing Range. Hot weather is accompanied usually by low humidity.

The predominant soils of the forest country of the foothills and mountain slopes are podzolized sandy or silty loams from metamorphic rocks, sedimentary sandstones, mudstones and shales chiefly of the Ordovician, Silurian and Jurassic periods, and igneous intrusions mainly of granitic type. Soils of the northern, north-western and coastal plains are mainly sands and sandy loams of recent Tertiary origin. Soils of the extensive and virtually treeless plains of the western district are loams from weathering of newer basalt lava flows.

The occurrence of the following principal forest types is illustrated on the accompanying map facing (page 20).


These occupy the cool, higher rainfall zone in mountain country ; average annual rainfall 40 inches to over 70 inches, predominantly in winter and spring ; regular winter snows often lying up to six months at the higher altitudes; average elevations 1,500 ft.-4,500 ft., with extremes from 600 feet to the timber line at 6,000 feet; mild summer temperatures rarely reaching 100° F., cold winters with temperatures at higher levels falling to below 20° F. Soils generally deep, moist, fertile loams, predominant rock formations being granodioritic and porphyritic in the central and north-eastern highlands, and Jurassic sandstones and shales in southern localities. Topography usually steep, rough and often rocky, with mountain plateaux intersected by deep gullies. Best forest development is on the cooler and moister westerly and southerly slopes, this type of forest descending to lower elevations on these aspects.

Within the type, three zones are recognized, viz., alpine, alpine ash, and mountain ash respectively.

In the alpine zone, tree vegetation is intermittent and interspersed with high plain grasslands, swamps and rocky outcrops. Trees are stunted and dwarf in character, seldom exceeding 30 feet in height. The principal species is the multi-stemmed Eucalyptus pauciflora var. alpina (Snow Gum) which grows in pure stands over extensive areas of the north-eastern highlands. Other species occurring include E. kybeanensis, E. perriniana, E. stellulata, and stunted E. delegatensis and £. rubida. Undergrowth is light, consisting usually of snow grass and dwarf alpine shrubs. This type of vegetation occurs generally about 4,500 feet, descending lower on cold southerly or exposed sites.

The alpine ash zone abuts on the alpine zone, descending to 3,200 feet on southerly aspects and to 3,700 feet on drier northerly slopes. This zone extends from Mt. Macedon along the north-eastern highlands to the New South Wales border. The predominant species, Eucalyptus delegatensis, occurs in extensive pure stands and on the margin of the zone in mixture with E. regnans, E. nitens, E. rubida, E. fastigata, E. radiata and E. pauciflora var. alpina. Undergrowth as a rule is not heavy except after fire.

The mountain ash zone is located below the alpine ash zone, descending on the average to 1,500 feet and to 600 feet on wet, southerly aspects and in sheltered gullies. The best forests are on deep, fertile, well-drained soils on sheltered southerly slopes. These forests occur chiefly in the Otway and south Gippsland ranges, and in the eastern highlands mainly south of the Dividing Range from Mount Disappointment to Mount Baldhead in the east. The principal species. Eucalyptus regnans, grows extensively in pure stands throughout this range, but the zone includes also pure and mixed stands particularly of E. viminalis, E. obliqua and £. goniocalyx. Undergrowth is very luxuriant and hygrophyllous in character; in the gullies Acacia melanoxylon, Nothofagus cunninghamii, and Atherosperma moschatum frequently form a second story, with tree ferns and other moisture-loving shrubs as a dense understory.


I MOUNTAIN FORESTS. Including Mountain Ash, Alpine Ash, Snow Gum, and non-productive Alpine areas






(Foothill Forests)

This type    is by far the most extensive    in    the    State, occupying

practically all    the country along and south    of    the    Dividing Range,

excluding the    high-rainfall mountain areas and    the    western basaltic

plains. Climate and soils vary considerably.    Annual    rainfall averages

20 in.-45 in. predominantly in winter and early spring ; elevations range from sea level to 3,000 feet; snowfalls are infrequent and of short duration except at the higher levels ; summers are long and dry. Soils are mainly loams derived from sedimentary rocks, with tertiary sands and gravels on the coastal plains. The best forests are on well-drained foothill slopes from 500 ft.-2,000 ft. elevation.

Essentially the forests comprise mixed stands of varied composition with limited areas of pure forest, and for convenience in description may be considered in four zones.

In the western coastal zone extending from the South Australian border eastwards to Port Phillip Bay, soils generally are poor tertiary sands and gravels, rainfall 20 in.-30 in. and elevations below 1,000 feet. The two main species are E. baxteri and E. obliqua, associated species including E. ovata, E. vitrea, E. radiata, E. aromaphloia, E. vimirtalis and in the Otway Peninsula E. globulus.

In the west-central hill zone from Mount Macedon east to the Grampians, soils are mainly clay loams from Ordovician sandstones and shales, rainfall from 25 in.-40 in., and elevations 1,000 ft.-3,000 ft. The predominant species are E. obliqua and E. radiata. Associated species include E. baxteri (Grampians), E. macrorrhyncha, E. elaeophora, E. radiata and E. dives on drier sites, E. globulus var. bicostata (Pyrenees and Mount Cole), E. rubida (Wombat State Forest), E. vimirtalis, E. ovata and E. aromaphloia. Undergrowth is usually of medium density, xerophilous, and comprised mainly of leguminous and heathy shrubs.

The north-eastern zone comprises foothills mainly north of the Dividing Range from 1,000 ft.-3,000 ft. in elevation. Soils are derived chiefly from metamorphic and sedimentary rocks ; rainfall 25-in.-40 in.; summers warm and dry ; frequent winter frosts. The composition of the forests is very varied, and pure stands of any extent are rare. The predominating species are E. obliqua on moister ridges and slopes and E. macrorrhyncha on drier sites. Principal associated species include E. goniocalyx, E. globulus var. bicostata, E. ovata, E. viminalis, E. radiata, and on dry, shallow sites E. maculosa, E. dives, E. polyanthemos and E. elaeophora. Undergrowth is of medium density and height growth, consisting generally of xerophilous shrubs.

The Gippsland foothill and coastal zone includes all the country from sea level up to 3,000 feet elevation, excluding any within the mountain forest zone, extending east from Port Phillip Bay to the New South Wales border. Rainfall varies from 25 inches to over 40 inches, in the eastern half of the zone being well distributed throughout the year, and in the western half predominantly in winter and early spring.

Winter temperatures are mild, in summer warm to hot. On the coastal plains, soils are chiefly teritary sands, often over limestone, and in the hills clay loams from Silurian and Ordovician formations, Devonian sandstones, and metamorphosed rocks. Forests are essentially of mixed hardwood types, with occasional pure stands of limited extent on specific sites. In the eastern half of the zone, E. scabra and E. sieberiana predominate in the coastal belt, principal associated species including E. bosistoana, E. botryoides, E. muelleriana, E. consideniana, E. sideroxylon, E. obliqua, E. macrorrhyncha, E. baxteri, E. polyanthemos, E. goniocalyx and E. radiata. In the western half, E. obliqua and E. radiata are the most abundant and widely distributed species, other prominent representatives including E. viminalis, E. goniocalyx, E. baxteri and E. sieberiana. Undergrowth is often dense, various acacias being prominent, and in damp gullies in the eastern half forms dense so-called “ jungles ” of semi-tropical character.

Except on the poorest sites, forests of this type constitute a valuable source of commercial hardwood timber. The fire hazard in summer is relatively high, due largely to the inflammable nature of the vegetation, but the majority of species are comparatively fire-resistant and possess strong recuperative powers.


The principal zone of occurrence is on the low foothills north of the Dividing Range between the Wimmera and Goulburn rivers. Red ironbark (E. sideroxylon) is also found extensively in the mixed forests of East Gippsland, on stony soils of the Lerderderg river locality, and on dry, stony, coastal sites in the vicinity of Airey’s Inlet.

The zone of major occurrence is characterized by low annual rainfall averaging 20 inches ; long, dry summers with frequent high temperatures and occasional drought, and sometimes severe winter frost. Permanent streams are few, topography undulating, average elevation 800 feet. Soils are chiefly shallow sandy or clay loams over clay, from Ordovician sandstones and shales.

The forests are open and typically mixed, with some pure stands on sites favourable to a particular species. The main components are limited to E. sideroxylon, characteristic of the drier ridges and upper slopes, and E. leucoxylon and E. hemiphloia on the lower slopes and flats. Associated species include E. elaeophora, E. macrorrhyncha and E. polyanthemos on dry, stony ridges, and E. melliodora and E. camaldulensis on the alluvial flats. Undergrowth is sparse to absent.


This type is confined to alluvial plains in the north and west of the State and occurs under two sets of environmental conditions, viz., in the 10 in.-18 in. rainfall zone on heavy alluvial soils bordering the Murray and Goulburn rivers and adjacent lagoons which are periodically

inundated by seasonal floodwaters, and on recent sandy loams of the western plains adjacent to the South Australian border in the 24 in.-28 in. rainfall belt. Topography is typically flat at elevations of 250 ft.-500 ft. Summer temperatures are high and severe frosts common in winter. In the riverain forests, normal flooding is from October to December, but occasionally floodwaters may remain on the low-lying ground for up to twelve months.

The principal species is E. camaldulensis which almost invariably forms pure stands. Best growth is on the lower ground which receives regular flooding. Its main associate along the rivers and lagoons is E. largiflorens which forms open pure stands on the higher ground reached only very occasionally by floodwaters, and on the western plains E. leucoxylon and E. largiflorens. Undergrowth is light and consists mainly of grasses and reeds.


Although not strictly classifiable as “ forest ”, this tree vegetation occupies extensive areas in the north-west. This is an arid region, with annual rainfall from under 10 inches to 16 inches, practically confined to winter. Summer temperatures and evaporation rate are high, with numerous days of hot, dry, northerly winds and periodic drought years ; occasional severe frosts. Soils are pure Tertiary sands or light sandy loams over limestone; permanent watercourses are non-existent; topography a slightly undulating raised estuarine plain with east-west sand ridges up to 30 feet high ; general elevation 200 ft.-300 ft.

The main tree vegetation consists of a number of species of dwarf, usually multi-stemmed eucalypts seldom over 20 feet in height in mixed stands. These develop an abnormally swollen root-stock and are extremely drought-resistant. The sparse undergrowth is comprised of xerophytic shrubs and native grasses. Associated tree species include Callitris hugelii, Casuarina cristata, and Myoporum platycarpum, with E. camaldulensis and E. largiflorens along watercourses and lagoons. Except for minor local uses, the mallee eucalypt stands have no commercial value but are extremely useful in protecting the loose sandy soils from erosion by wind.


These terms are used to describe the open and widely dispersed tree growth, generally unimportant from a forestry angle, of the western basaltic plains. Soils are a chocolate loam, topography gently undulating, rainfall 20 in.-30 in., summer temperatures high. The main species represented are E. leucoxylon, E. pauciflora, E. hemiphloia, E. melliodora, E. ovata, E. viminalis and E. camaldulensis but these occur more as scattered trees and clumps of trees than in stands. E. cladocalyx and other eucalypts have been extensively planted in belts to provide protection from wind for stock and timber for local use.

E. camaldulensis Dehn. (syn. E. rostrata Schlecht)—River Redgum.

Native to all mainland States. In Victoria grows generally along lowland watercourses throughout the western half of the State and in the north-east, but in forest formation its main occurrences are along the River Murray and its principal tributaries, and on the plains between the Grampians and the South Australian border.

As a forest tree grows under two sets of conditions—on alluvial soils adjacent to rivers, old watercourses and lagoons subject to annual or periodic inundation by floodwaters or where there is permanent subsoil moisture in low rainfall (10 in.—18 in.) areas, and on the heavier soils of the western plains in the 24 in.-28 in. rainfall belt. Can withstand high temperatures, severe drought and moderate frost. Elevation 100 ft.-l,200 ft.

Growth rapid under favourable conditions ; attains height of 80 ft.-120 ft., with diameters to 14 feet; tends to develop spreading crown, with short massive bole which is frequently not straight; regenerates readily from seed and coppice, and produces abundant seed. Almost invariably in pure stands, but associates occasionally with E. largiflorens along rivers and with E. leucoxylon on the plains.

Bark smooth and greyish-white, shedding in thin leaves or flakes.

Juvenile leaves opposite, narrow to broad-lanceolate ; mature leaves alternate, 3 in.-8 in. long and tapering gradually from base to tip.

Buds and flowers on rather long pedicels in clusters of four to eight on short peduncles. Operculum conical, one and a half to two and a half times longer than the goblet shaped calyx tube.

Fruit hemispherical, 3/10 in. x 2/10 in. with prominently projecting valves and a domed rim.

E. delegatensis R. T. Baker (syn. E. gigantea Hook.)—Alpine Ash.

Indigenous to Victoria, New South Wales and Tasmania. Its Victorian range is from Mount Macedon easterly to the New South Wales border.

Favours good, well-drained soils derived from basaltic and granitic type rocks but also grows on shallower soils from Silurian sandstones and metamorphosed formations. Topography typically rugged and broken with much rock outcropping on steeper slopes. Moderate summer and cold winter climate ; heavy snow for up to six months of the year and severe frosts ; rainfall 40 inches to over 70 inches. Optimum altitude range 3,100    ft.-4,000 ft., with extremes

2,400 ft.-5,200 ft.

On better class sites grows to 250 feet, with diameters to 10 feet and merchantable long lengths to 140 feet. On poorer soils, exposed situations and towards the upper altitude limit tends to become short-boled and branchy. Occurs usually in even-aged pure stands, but also in mixture with E. radiata and E. rubida, and less frequently E. regnans, E. viminalis and E. nitens and at its upper altitude range E. pauciflora var. alpina. Growth rapid when young ; reproduces freely from seed but does not produce coppice shoots.

Bark on the lower half of the trunk reddish, very thick and woolly (like a stringybark); upper bark smooth, pale bluish-grey or white and falls in long, thin strips.

Juvenile leaves bluish-green and more rounded than the mature leaves which are dark-green, alternate, 8 in.-lO in. long, tapering and often curved.

Buds and flowers in clusters of seven to fifteen. Operculum hemispherical and shorter than the calyx tube.

Juvenile leaves paired, almost sessile and elliptical. Mature leaves stalked, tapering, bluish-green and somewhat shiny. 4 in.—6 in. long and about 1 inch wide.

Buds and flowers in clusters on rather long pedicels, the peduncles somewhat flattened. Operculum hemispherical and shorter than the calyx tube.

Fruit narrow and pear-shaped, 3/10 inch in diameter, shining and usually with a well-defined dark-red rim, valves enclosed.

E. viminalis Labill.—Manna Gum.

Indigenous to Victoria, South Australia, Tasmania, New South Wales and Queensland. Widely distributed in Victoria, occurring in all districts except north of the Divide in the north and north-west. Its main occurrence as a commercial tree is in the central highlands and the Otway ranges.

Prefers deep fertile soils, moist but well drained, in sheltered gullies. In the hill country, frequently occurs in narrow belts along the banks of streams in pure stands or in mixture with E. ovata. In the mountain ranges, often found immediately below stands of E. delegatensis or E. regnans.

A handsome, tall, straight tree with shapely crown on favourable sites, growing to over 200 feet in height with log lengths to 120 feet and diameters to over 6 feet. At lower elevations usually a small tree of more spreading habit and on the coastal lowlands develops a persistent rough bark. Rainfall 25 inches to over 60 inches, elevations from sea level to 4,800 feet. Occasionally in pure stands, but more commonly in mixture particularly with E. radiata and E. goniocalyx, also E. rubida, E. fastigata, E. regnans, and E. delegatensis at high elevations, and E. globulus var. bicostata, E. obliqua. E. ovata, E. botryoides and E. macrorrhyncha at lower levels. Regenerates moderately well from both seed and coppice.

Bark rough and persistent for a few feet at the butt, or quite smooth throughout, white to yellowish-white and often hanging from the branches in long ribbons.

Juvenile leaves opposite, sessile and somewhat wedge-shaped. Mature leaves stalked and tapering, 3 in.-6 in. in length.

Buds and flowers usually in groups of three on short peduncles. Operculum hemispherical and usually longer than the calyx tube.

Fruit almost sessile, domed, 2/10 in.-3/10 in. in diameter, with a prominent rim and protruding valves.

(The mature tree of this species is difficult to distinguish from Candlebark (£. rubida). However, the juvenile leaves of E. rubida are quite different, being glaucous, almost round, not tapering as in E. viminalis.)


Genus Acacia

The genus Acacia consists of over 800 species, two-thirds of which occur in Australia, all but one of which are endemic. In Victoria about 80 species are represented, the majority of which do not reach tree status. The main species of economic importance in Victoria are A. pycnantha Bth., Golden Wattle, A. melanoxylon R.Br., Blackwood, A. mearnsii DeWild, (syn. A. molissima Willd.) Black Wattle and A. dealbata Link.. Silver Wattle.

A. pycnantha Bth., Golden Wattle.

Native to Victoria, New South Wales and South Australia. The tree is usually too small for anything other than fuel for which it is prized. The bark is a useful source of tannin.

A. melanoxylon R.Br., Blackwood.

Native to Victoria, New South Wales, South Australia and Tasmania. Grows to 100 feet, the wood is dark to pale-brown, often figured and therefore useful for furniture and fittings.

A. mearnsii DeWild. (syn. A. molissima Willd.) Black Wattle.

Native to Victoria, New South Wales, South Australia and Tasmania. The bark of this species is valued for its tannin content ; the wood burns freely.

A. dealbata Link., Silver Wattle.

Widespread in Victoria ; also in New South Wales and Queensland. Useful as firewood ; the gum is occasionally collected. The bark is of inferior quality for tanning purposes.

Genus Casuarina

This genus comprises some twenty species mainly Australian. There are eight well-defined species in Victoria the following four species of which yield useful timber :—

C. suberosa Ott. and Diet., Black Sheoke.

C. luehmannii R. T. Baker, Buloke.

C. stricta Ait., Drooping Sheoke.

C. cristata Miq. (syn. C. lepidophloia F.v.M.) Belar.

C. suberosa Ott. and Diet., Black Sheoke.

Native to Victoria, New South Wales, Queensland and Tasmania. It is widely spread in Victoria with the exception of the north-west. Up to 40 feet in height. The timber is dark and durable and can be used for veneers, mauls and tool handles ; a good fuel ; the branches have less fodder value than the other species.

C. luehmannii R. T. Baker, Buloke.

Native to Victoria, and the interior of New South Wales, South Australia and Queensland. In Victoria it is confined to the north-west and south. Up to 50 feet in height. The timber is hard and durable, and strikingly figured by the broad medullary rays ; useful for furniture and cabinet work ; durable in the ground and is a good fuel.

C. stricta Ait., Drooping Sheoke.

Native to Victoria and throughout temperate Australia. It is widely spread in Victoria. Up to 30 feet in height. The timber is reddish-brown, hard and tough ; the prominent dark medullary rays make the timber useful for cabinet work, furniture and turnery ; does not last particularly well in the ground but is a good fuel.

C. cristata Miq. (syn. C. lepidophloia F.v.M.) Belar.

Native to Victoria, New South Wales and South Australia. In Victoria it is confined to the far north-west. Occasionally up to 70 feet in height. The timber is pale outside but the heartwood is dark brown, tough and durable ; useful for tool handles, staves, cabinet work and fuel.

Genus Callitris

Callitris is represented in each Australian State and New Caledonia ; it comprises fourteen species and a number of sub-species. In Victoria five representatives occur, the following three of which yield timber of commercial value :—

C. hugelii (Carr.) (syn. C. glauca R.Br.) White Cypress Pine. C. preissii Miq. ssp. murrayensis Joy Garden (syn. C. propinqua R.Br.) Slender Cypress Pine.

C. endlicheri (Pari.) (syn. C. calcarata (R.Br.) Red Cypress Pine.

C. hugelii (Carr.) (syn. C. glauca R.Br.) White Cypress Pine.

Native to Victoria, New South Wales, South Australia, Western Australia and the Northern Territory. In Victoria it is confined mainly to the central-north and far north-west. The timber varies from light to dark brown and is fairly dense ; it takes a good polish, is resistant to termites and is useful for furniture, linings, weather boards, flooring and fencing; it is a good fuel but burns rather too readily. Up to 80 feet high.

C. preissii Miq. ssp. murrayensis Joy Garden (syn. C. propinqua R.Br.)

Slender Cypress Pine.

Native to Victoria, New South Wales and South Australia. It is confined in Victoria to the central-north and far north-west but has been recorded from near Lethbridge north of Geelong. Its uses are similar to those of the White Cypress Pine. Up to 60 feet high.

C. endlicheri (Pari.) (syn. C. calcarala R.Br.) Red Cypress Pine.

Native to Victoria, New South Wales and Queensland. In Victoria it is restricted to the eastern and north-eastern parts of the State. The timber is useful for interior work, furniture and cabinet work but contains more knots than the White Cypress Pine ; the tree is rarely more than 50 feet high.
