E. eugenioides, Sieb.

SIEBER'S definition of E. eugenioides is as follows:—

E. operculo mucronulato, umbellis lateralibus racemosis, ramulis teretibus, foliis inæqualiter oblongolanceolatis (Sprengel's Curæ Posteriores, iv, 195), a description which would have rendered it impossible to state what species was meant, had not a specimen, named by Sieber, been in existence.

It is also described in Mueller's “Eucalyptographia.” The species may be described as follows:—

Vernacular Names.—It is usually known simply as “Stringybark.” It is often known as “White Stringybark” in this State and also in Victoria (A. W. Howitt), but the timber is often reddish, and hence it bears the name of “Red Stringybark” also. In those cases E. capitellata from the same district usually bears the name of “White Stringybark!”

Juvenile Foliage.—Specimens of the type (Sieber's No. 479) are just—only just—past the opposite stage. They are lanceolate, under ¾ inch wide at the outside, and up to 2½ inches long. Venation strongly marked. Leaves undulate and young shoots warty. (See fig. 2, pl. 40.)

Mueller has figurednote the juvenile foliage of the species in the Eucalyptographia, and I accept it as certainly belonging to the species, although the figure would have had enhanced value had the locality of the specimen been given.

Mature Leaves.—These are generally much thinner and more delicate in texture than those of E. capitellata and E. macrorrhyncha; the leaves are sometimes very shiny and much thicker than others. They are also of a richer green, more shapely, graceful and Eugenia-like, a circumstance which led to the adoption probably of the specific name.

Buds.—The buds are clustered and often very much crowded into heads, by which the inflorescence assumes a very marked character. They always have pointed opercula, but rarely angular, as in E. capitellata, the points being sometimes so marked as to approach those of E. macrorrhyncha, but they are then fuller on the top, and do not show such a prominent edge at the base of the operculum. Sometimes, e.g., Sydney to Blue Mountains, they are arranged in a stellate manner.

Fruits.—Sieber having distributed no fruits with his type, I attach the following description of fruits from trees in the Sydney district, which have juvenile and mature leaves, and flowers practically identical with the type:—

They are nearly hemispherical, with the valves slightly exsert; but nearly globular fruits with the valves sunk, and the orifice constricted, may be taken off the same tree. Occasionally the fruit is quite flat-topped. The rim is often red, as red as those of E. hæmastoma ever are. They are slightly pedicellate, often crowded into more or less globular heads, but rarely compressed like those of E. capitellata.

Timber.—When freshly cut usually dark brown, but drying to a pale warm brown and even whiter. In some districts, however, the timber is distinctly red, even redder than the local E. capitellata timber.

1. E. scabra, Dum-Cours.

Following is the original description:—

E. à feuilles rudes, E. scabra, Hort. Angl.-Cette espèce me paroît être une des plus belles de ce genre, du moins relativement à son feuillage. Ses feuilles sont ovales, très entières, terminées par une pointe particulière, relevées en-dessous de nervures parallèles qui s' arrondissent, en s' anastomosant à une ligne environ des bords, fermes, un peu rudes au toucher, d'un beau vert, longues de 9 centimètres (3 pouces et demi), larges de 5 cent. et demi (2 pouces). Lieu id. Toujours vert. Cult. Orangerie. Celle des autres espèces et des plantes de la Nouvelle-Hollande.

De toutes les espèces de ce genre, il n 'y a que celles qui sont nommées E. resinifera et obliqua qui aient encore fleuri en France et en Angleterre.—(Dum-Cours. Bot. Cult. ed. 2, vol. 7, p. 279, 280).

We then find Sieber's No. 479 (the type of E. eugenioides) placed under the same name, in the following words:—

E. scabra (Dum-Cours, bot. cult. 7, p. 280) operculo subconico cupulâ paulo breviore, pedunculis axillaribus angulato—compressis petiolo æqualibus aut longioribus, floribus capitatis, foliis lanceolatis basi inæqualibus ramorum sterilium crispis, fertilium planis, saepe novellis cum ramis velutinis. In Novâ-Hollandiâ. E. eugenioides, Sieb.! plant. exs. nov.-holl., n. 479—(DC. Prod. iii, 218.)

Specimens referred to, Sieber's No. 479, and named E. scabra, Dum-Cours, are precisely matched by many specimens in the National Herbarium, Sydney, e.g., Wyee (A. Murphy).

2. E. penicillata, Hort.

E. penicillata, hortul. Ramuli et folia pilos breves fasciculatim congestos gerunt, demum glabra evadunt, interdum glabra nascuntur. Petioli 4 lin. longi. Folia basi inæqualia ovali—aut oblongo—lanceolata acuminata. Pedunculi in specim. Sieberiano petiolo æquales 4–5 flori, in specim. culto Noissettiano petiolo duplo longiores 15–20 flori (given as a synonym of E. scabra in DC. Prod. iii, 218).

3. E. acervula, Sieb. (Sieb. plant. exs. nov.-holl., n. 469).

Operculo conico capsulæ longitudine, pedunculis lateralibus petiolo brevioribus pedicellisque ancipitibus, foliis ovato—lanceolatis basi hinc valde excisa obliquis apice acuminatis. In Nova—Hollandia. Folii petiolus 3–7 lin. longus, lamina 4–5 poll. longa pollicem lata. Pedunculi 4 lin. longi omnes in ramis infra folio orti. Umbellæ 5–10 floræ. Florum alabastra 3 lin. longa.—(DC. Prod. iii, 217.)

All the specimens of Sieber's No. 469 that I have seen are in mature foliage and bud. I cannot separate them from Sieber's No. 479; in fact, they might have been taken from the same tree.

“31. Eucalyptus acervula, Sieb.—DC. l.c. 217, n. 10, Mém. Myrtac. Folia in supp. paullo latiora. Swampy plains towards the Plenty-range (F. Müller)” (Miquel in Ned. Kruidk. Arch. iv, 137, 1856). I have not seen this Victorian specimen.

  ― 234 ―

4. E. oblonga, DC.

Following is the original description:—

E. oblonga, operculo conico cupulæ longitudine, pedunculis lateralibus et axillaribus petioli longitudine compressis, umbellis 8–12 floris, foliis oblongis basi inæqualibus attenuatis apice mucronatis coriaceis aveniis.

In Novâ-Hollandiâ. Sieb.! plant exs. nov.-holl. n. 583. Alabastra oblonga utrinque attenuata ad apicem pedunculi subsessilia et eo paulo breviora. Folia 3–4 poll. longa, 9 lin. lata.—(DC. Prod. iii, 217.)

This is in leaf and young bud only. Some of the leaves are oblong; they are mucronate, shiny, very coriaceous, so that the venation cannot readily be seen. The buds are shiny, operculum pointed, calyx tapering into the short pedicel, making the bud symmetrical and of the shape of a “tip-cat.” I refer it, without doubt, to a form of E. eugenioides common on the Blue Mountains. I match it absolutely with specimens from Lawson (J. H. Camfield); Jenolan Caves (W. F. Blakely); and Mudgee (C. Marriott).

5. E. undulata, Herb. Vindob. (? Tausch., but label partly defaced) is a seedling or sucker branch of E. eugenioides, Sieb.

Var. nana, Deane and Maiden.

Figured and described in Proc. Linn. Soc. N.S.W., 1898, p. 799.

This is a shrub of 5 or 6 feet, forming a dense shrubby growth at Wentworth Falls, Blue Mountains, N.S.W. It has the stellate hairs (juvenile foliage) of the rest of the Stringybarks.

6. E. oleifolia, A. Cunn.

In his MSS. Journal I find the following entries:—

  • (a) At page 6: “Blackheath, 5th October, 1822, operculo hemispherico foliis (parvis) ellipticis ovali-lanceolatisve mucronatis acutiplanis, umbellis axillaribus pedicellatis 9–10 floris. A low shrub 2 feet high.”
  • (b) “A low shrub 1–2 feet high, verge of Regent's Glen.” This is probably also E. eugenioides, var. nana.

Mr. R. H. Cambage has also collected it on a sandstone plateau about 1,700 feet high at West Dapto. His note is: “Dwarf Stringybark, growing somewhat as a Mallee. Height, 2 feet 9 inches.”

7. E. ligustrina, DC.

Operculo hemisphærico mucronato cupulâ breviore, pedunculis axillaribus compressis petioli longitudine, floribus 6–8 sub-capitatis, foliis lineari-lanceolatis basi valde inæqualibus attenuatis apice acuminatis. In Novâ-Hollandiâ. Sieb. (?) plant. exs. nov.-holl. n. 617. Folia 2 poll. longa 4–5 lin. lata. Petioli et pedunculi 3–4 lin. longi. An E. salicifolia, Cav. Ic. 4 n. 376 (?).—(DC. Prod. iii, 219.)

All the specimens of Sieber's No. 617 that I have seen are in bud only, but they precisely match E. eugenioides, var. nana.

Note on E. salicifolia, Cav.

A specimen of Sieber's No. 617 in Herb. Vindob. (ex. Coll. Reichenbach, fil.) in old handwriting bears the label, “E. ligustrina, DC. Prod. iii, p. 219, n. 24. E. salicifolia, Cav. ic. iv, p. 24, No. 376!” with the words, “Spont. N. Holl. Sieb. 617,” in a later handwriting. It is E. eugenioides, Sieb., var. nana.

  ― 235 ―

At p. 152, Part VI, of this work this species is referred to E. amygdalina, and the determination of Sieber's No. 617 as E. salicifolia is, I believe, wrong. I give the original description of E. salicifolia, as Cavanilles' work is not in New South Wales:—

“376. Eucalyptus foliis lanceolatis, nervo dorsali inæqualiter partis, altera parte versus basim breviore.

“Haec species a reliquis distinguitur foliis altera parte versus basim breviori ut in Begonia et aliis plantis: nervuli sunt etiam adscendentes: umbellæ 7–10 floræ, axillares.”—(Cav. Icones, iv, p. 24.)

See also Metrosideros salicifolia (Gaertn. Sem. i. p. 171, t. 34; Lamarck Illustr. t. 421, f. 4). Specimens (so named) have also been recorded from “Bay of Islets, Cape Grafton, Endeavour's River, Point Lookout, Possession Island,” as collected by Sir Joseph Banks, but I have not seen them. For geographical reasons they could not be E. amygdalina, and it is very improbable that they are E. eugenioides. See also Dryander's “Chloris” (Ann. Bot. ii, 524, 1806).


IT appears to be confined to eastern Victoria, New South Wales, from south to north, on the Dividing Range and its spurs, and east of them, and to southern Queensland.


The Victorian forms (often referred to in the writings of Victorian botanists as E. piperita), as a rule have fruits which are more or less pilular, i.e., with sunk valves, thus approaching E. piperita, but the fruits appear to be never urceolate, as in that species.

Some of them, e.g., Eureka Hill, Tinker Creek, Gippsland; Drouin West; also Osler's Creek (A. W. Howitt), have juvenile leaves which vary from narrow to broadish.

Mr. (now Dr.) A. W. Howitt wrote to me, “The White Stringybark forms forests in Gippsland, for instance at Toongabbie, between Stratford and Bairnsdale, Bairnsdale and Buchan at the Lakes Entrance, in Croajingolong. It also occurs throughout the mountainous districts. It grows to a good size, is free from gumveins, and is a useful timber. Its western limits are probably Traralgon and Woodside.”

Following are Victorian specimens in the National Herbarium, Sydney, collected by Dr. Howitt.

Macalister River.—Fruits in heads, orifice small; source of Wild Horse Creek, 3,000 ft.; Drouin West; Stockyard (the river banks); Agnes Bridge, very long opercula; “Yellow Stringybark,” Stony Creek, Nicholson River, Bairnsdale; the suckers intermediate in character.

“A Stringybark growing in the clayey flats (post-Pliocene?) at Toongabbie, near the foot of the hills. From a moderately large tree, say 100 ft. ‘Yangoura’ of the blacks” (A. W. Howitt).

A specimen from Blackburn, near Melbourne (C. Walter) has the valves of the fruits slightly exsert.

  ― 236 ―


Southern Localities.—Twofold Bay (J.H.M.), Wyndham and Bembooka (A. W. Howitt); Conjola, near Milton, with very long opercula (W. Heron); south of Nowra, from Jervis Bay (J.H.M.); Shoalhaven River, also Diggers' Creek (W. Forsyth and A. A. Hamilton), with filiform pedicels; Kangaloon (J. L. Bruce); Barber's Creek (H. J. Rumsey); Wingello (J. L. Boorman), medium trees, detected by short leaves and absence of glaucous tint. “Red Stringybark,” in contradistinction to “White Stringybark” (E. capitellata), a reversal of this nomenclature being more common in other parts of New South Wales. A second collector (A. Murphy) confirms Mr. Boorman's report of the local nomenclature.

Berrima (see notes under E. capitellata).

The Peaks, Burragorang (R. H. Cambage), Kangaroo Valley and Bowral to Bullio (J.H.M. and R. H. Cambage). These specimens are indistinguishable from Sieber's type of E. acervula, No. 469, but are eugenioides, showing transit to one of the forms included by Mr. Baker in his Wilkinsoniana.

Hilltop, with specially marked white-dotted fruits and elongated opercula (J.H.M.).

Sydney district, common on the Wianamatta shale, but also found on sandstone. Following are some Sydney district localities:—Homebush (J.H.M.); Concord Park (R. H. Cambage); Bankstown and Cabramatta (J. L. Boorman); Hurstville (R. H. Cambage), the valves sunk; La Perouse (W. W. Froggatt); Peat's Road (H. Deane); Newport (R. H. Cambage).

Some trees found by J. J. Fletcher at Gladesville, photographed by R. H. Cambage, and examined by all three of us, have a flaky bark (somewhat like E. resinifera), than that of a true Stringybark; probably showing hybridism.

Western Localities.—To the foot of the Blue Mountains from Sydney, it is rather common. It is the commonest Stringybark on the Blue Mountains, occurring all over the range, and at all heights. Compared with the other rather common Blue Mountain Stringybark (E. capitellata), the timber is redder (!) The juvenile foliage is narrower, and not glaucous, like that of E. capitellata. The fruits of E. eugenioides on the Blue Mountains are not often exsert; instances to the contrary are Springwood (H. Deane); Mount Wilson (Jesse Gregson), with inner bark very yellow.

Jenolan Caves (W. F. Blakely). Collector's note:—“The bark of these trees is of a light reddish colour on the inside; the outside is of a dirty grey colour, or weather-beaten, and is very ridgy; the ridges run out to nothing as they approach the top of the tree. The bark is of the same colour from the bottom to the topmost branch, and is of a rather rough nature.”

At Capertee (J. L. Boorman) and Mudgee (Dist. Forester C. Marriott) it is known as “White Stringybark.”

  ― 237 ―

E. eugenioides does not appear to go further west than Jenolan Caves and Mudgee.

“Bastard Stringybark” (Penrith: J. L. Boorman, January, 1900). I desire to invite attention to an interesting form of this species. The fruits are smaller than is usual and nearly globular. They are on nearly filiform pedicels of about 2 lines; the common peduncle is twice that length, and more. The bark is harder and denser (less stringy) than those of the normal species—more “bark bound”; a character also noted under E. capitellata. Perhaps hybridism is indicated in this case. The plant is indubitably E. eugenioides, though, from examination of the fruits alone, it might reasonably be supposed to be E. hæmastoma, var. micrantha.

Northern Localities.—Most of the northern specimens have the rims red and prominent, and the valves slightly exsert.

“Good timber, cut for sleepers. Yellow inner bark, between the rough and the inner bark; the fibrous portion very tough.” Wyee (A Murphy). The fruits are slightly constricted, and in heads; the filaments turn brownish-red on drying.

Stringybark, free splitting; bark between sap and outside yellow. St. Alban's district, Hawkesbury River (A. Murphy). Transit to E. Muelleriana.

Wallsend (W. W. Froggatt).—Fruits rather small, rim red and conspicuous, valves slightly exsert, leaves broadish (?); Booral (A. Rudder, No. 4); Wallsend (J. L. Boorman); Booral (A. Rudder, A. 29).

“Stringybark, height about 60 ft., diam. 18 in., mould over shale,” near Underbank, Upper Williams River (A. Rudder, G. 10).

Pokolbin, No. 1,486, R. H. Cambage. Near to E. Wilkinsoniana, R. T. Baker.

Stewart's Brook.—Rim of fruit red and pronounced (J.H.M.); Moggrani Mountain, Gloucester (J.H.M.); Upper Hastings River; cutting near Yeldham's. Fruits slightly exsert and rim pronounced (J.H.M.); Macleay River (Forester W. Macdonald).

Murrurundi (J.H.M. and J. L. Boorman). Valves slightly exsert, rim broadish, hemispherical, slightly depressed, with short filiform pedicels, connecting with the “Bastard Stringybark” of Penrith.

Collaroy (J.H.M. and J. L. Boorman), showing white dots and a slight ribbing of the fruits.

Near Cemetery, Tingha (R. H. Cambage); with fruits a little more subcylindrical and perhaps a little more domed than the type. Specimens from the same locality with nearly pilular fruits and very narrow juvenile foliage.

Near 11-mile post, Inverell to Tingha (R. H. Cambage). Form with even narrower leaves than the type.

  ― 238 ―

Tingha to Guyra, 19 miles from the latter place (J.H.M. and J.L. Boorman). Juvenile leaves intermediate. Mature leaves broadish. Fruits (from same tree) flat-rimmed, domed; valves exsert and sunk; hemispherical and inclined to be sub-cylindrical.

I place this specimen under E. eugenioides, and it certainly seems to form a connecting link between the Tingha specimens and the supposed hybrid which follows.

Between Tingha and Guyra, 19 miles from the latter (J. L. Boorman). “Stringybark,” medium-sized trees growing in swampy ground in company with that of E. stellulata and E. nova-anglica. An interesting form; leaves broad, thickish. None of the fruits with exserted valves, which is unusual in northern specimens. I am of opinion that here we have a hybrid between E. eugenioides and E. stellulata.

Fruits in heads, slightly constricted, valves sunk. Tent Hill (E. C. Andrews).

Small fruits in heads, valves not exsert, Styx River (A. W. Howitt). I have other specimens from the same locality showing close affinity to E. Muelleriana.

Walcha (J. F. Campbell). Fruits rather exsert, and rim inclined to be domed. Shows affinity to E. macrorrhyncha. Ascending New England from Port Macquarie, this species was first observed about Yarrowitch. Thence it was not uncommon in the Tia district, where it is known as “Red Stringybark,” and used for timbering the mines at Tia, and also locally for flooring-boards. This species shows a double operculum (J.H.M.).

Tenterfield to Sandy Flat (J.H.M.)—Fruits very similar to those of Sydney, e.g., Concord Park (believed to be typical), hemispherical, and somewhat exserted valves. Buds very compressed, almost like capitellata. I figured this (Plate 4, Part I) as E. Muelleriana, and I now put it under E. eugenioides with doubt. It certainly is a transit form.

Drake to Richmond River (A. Hagman); Drake (E. C. Andrews), with rim of fruit rather sharp and valves exsert (transit to E. Muelleriana).

Foot of Mt. Lindsay (W. Forsyth); Moonambah, Richmond River (W. Baeuerlen); valves slightly exsert.


Nerang, near Tweed Heads (F. M. Bailey). Small fruits with sharp rim, valves rather prominent.

“Stringybark.” Yellow inner bark. See fig. 16, pl. 38, Stanthorpe (J. L. Boorman). A eugenioides-Muelleriana form.

“Yellow Stringybark,” Landsborough, North Coast Railway (P. MacMahon). A pale-coloured timber, with stains of bright yellow running through it.

1. E. capitellata, Sm.

There is no sharp line of demarcation between E. eugenioides and E. capitellata, intermediate forms occurring between them in regard to buds, fruit, leaves, and even timber.

Some fruits show a tendency to E. capitellata in having fruits larger and more “squatty” or compressed than those of E. eugenioides. But the valves of the fruits are not so exserted, nor are the buds so flat and angular as those of E. capitellata usually are. The buds are, in fact, those of E. eugenioides.

E. eugenioides displays a tendency to form globular masses of closely-packed sessile fruits, after the manner of E. capitellata. These globular masses present such a different appearance to the ordinary form of E. eugenioides that they may, at first sight, be reasonably supposed to form a variety, but we have many gradations between them and the ordinary form.

The state of being capitate is by no means confined to E. capitellata, and seems to me induced by exuberance of floriferousness. For example, at Newport, near Sydney, where E. eugenioides was flowering as freely as I have ever seen it, and covered with honey-seeking insects, on the same twig we find dense heads of fruits and more open heads with distinctly pedicellate fruits. There we have also the roughened rim and the white-dotted fruits.

To recapitulate somewhat, we have:—

E. eugenioides fruits may be sessile; they may be compressed; they may precisely resemble those of E. capitellata in shape, as regards the sunk valved forms. The valves are rarely, if ever, so exsert as in some forms of capitellata.

In E. eugenioides the buds are smaller; occasionally slightly angled, but never to the extent that those of capitellata are (with the possible exceptions referred to, e.g., young buds of Berrima and Wingello, pp. 215, 216).

Sometimes they, like the leaves, are shining like those of E. capitellata often are.

The juvenile leaves may be broadish as in Figure v in Howitt, Trans. Roy. Soc. Vict., 1890–1, vol. 2, pl. 14, fig. 4. With these I place specimens collected in Gippsland (Toongabbie, Bruthen, Eureka Hill, Tinker Creek), by A. W. Howitt. A figure of one of Mr. Howitt's natural seedlings has just been alluded to, and fig. 1 of the same plate, considered by Mr. Howitt to be E. piperita, is the same form.

Such specimens as these (and other instances have been referred to by me) show that there are intermediate stages between E. eugenioides and E. capitellata, and that the evidence of seedlings, at one time believed to be infallible, breaks down. At the same time, juvenile foliage (whether of seedlings or suckers) is most valuable. Yet here we have additional evidence pointing to the conclusion that every character in Eucalyptus is unstable.

  ― 240 ―

2. E. macrorrhyncha, F.v.M. (See E. macrorrhyncha.)

3. E. Muelleriana, Howitt. (See E. Muelleriana.)

4. E. piperita, Sm.

In the “Flora Australiensis” E. eugenioides is reduced to a variety of E. piperita, but it has since been shown to be an undoubtedly good species, its affinities being more with E. capitellata than with E. piperita. From the latter it is easily distinguished in the living state by the strong fibrous character of the bark which extends to the small branches, the other species having a bark of the texture of E. amygdalina, and being only half-barked in general like E. pilularis. The fruits of E. piperita are more contracted at the top with a thin rim, whereas those of E. eugenioides have a well-marked rim, sometimes flat, but generally raised. The juvenile foliage and timber are also very different.

Following are the reports on the Stringybark oils dealt with in this Part, taken from Messrs. Baker and Smith's “Research on the Eucalypts.” Each form was only subjected to one or at most two distillation :—

On these figures, E. capitellata and E. eugenioides are very closely related. I invite attention to the relationships of the other species on the figures given; they can be discussed in a chemical or pharmaceutical journal.
