CCL. E. Bakeri Maiden.

In Journ. Roy. Soc. N.S.W., xlvii, 87 (1913).

FOLLOWING is the original description:—

Frutex altus similis Mallee, vel arbor parva 30–50' alta. Trunci cortex dura et squamosa. Ramuli laeves. Lignum durum, grave, rubrum. Folia juvena obscuro-virentia, concoloria, linearo-lanceolata, vix acuminata, 9 cm. longa, 1 cm. lata, oleosa, indistincte venosa, penniveniis, vena peripherica a margine remota. Umbellæ plerumque axillares, multifloræ, saepe 10–13 floræ. Operculum elongatum calycis tubo multo longiore, cujus diameter leniter latior est. Fructus diametro circiter 5 mm., truncato-spheroidei. Valvarum apices subulati, 2 mm. exserti.

A large shrub or small, pendulous, Willow-like tree, attaining a height of 30–50 feet, forming a single stem or stooling from the ground.

Bark dark, box-like, or hard and scaly up to its branches, falling away in long flakes, rough at the butt, branches clean, bluish-green or pale-yellow to white right up to the tips.

Wood hard and heavy, of a deep red when freshly cut, becoming browner with age, the grain of the timber fibrous, very tough, reputed to be an excellent timber for wheelwrights' work.

Juvenile leaves dull green on both sides, linear-lanceolate, hardly acuminate, about 6 or 7 cm. long, the venation not distinct, the intramarginal vein close to the edge, the lateral veins penniveined, plentifully besprinkled with oil-dots and the branchlets angular and glandular.

Mature leaves linear-lanceolate, petiolate, acuminate or with a hooked tip, bright-green, dull-shiny, richly covered with oil-dots, venation indistinct, the intramarginal vein distinct from the edge, the lateral veins penniveined. Average dimensions 9 by 1 cm.

(If the species were gregarious, it would probably be found to be a valuable oil-yielding species.)

Flowers.—Umbels mostly axillary and flowers numerous, often 10–13 in an umbel, which sometimes takes on a stellulate appearance. Operculum elongated, very much longer than the calyx-tube, which is of slightly increased diameter, and which tapers, somewhat abruptly, into the short pedicel. The common peduncle about 1 cm.

Anthers small, renantheroid, but the two cells more united than in the Renantheræ; spherical gland at top and back.

Fruits.—Small, about 5 mm. in diameter, truncate-spheroid, the tips of the valves awl-shaped, and protruding 2 mm. from the orifice.

Enclosing the valves, and torn by the tips of them as the fruit ripens is a thin, white membrane, which gives the rim and orifice a whitish appearance, and which, if present in all, is only obvious in a few species of this genus.

This is a specially interesting species, rich in oil, which I name in honour of Mr. Richard Thomas Baker, who has done very valuable work in connection with this genus.

Range.

It extends from northern New South Wales to Central Queensland, so far as we know at present.

Following are specimens in the National Herbarium, Sydney. I am satisfied that careful research will bring many new localities to light.

NEW SOUTH WALES.

1. “Willowy Eucalypt,” Warialda, N.S.W. (W. A. W. de Beuzeville, No. 3).

2. Ticketty Well, Wallangra (E. H. F. Swain, July, 1911. The type. J. L. Boorman, December, 1912). “Tree-like Mallee,” 28 feet high and 5 inches in diameter, wood brown, bark grey up to 6 feet, then yellowish. Ticketty Well, locality of type. (Forest Guard A. Julius, Nos. 17 and 19). The leaves of these specimens are broader than those of the type (Journ. Roy. Soc. N.S.W., liii, 68, 1919).

Queensland.

3. “Small bush, grows up to 10 feet high, grows very thickly on the poorest soil, where there is no Ironbark cover.” Warwick (Forester W. E. Moore, through C. T. White).

4. Near Jericho (J. L. Boorman). It is a Mallee, and it would appear that Mallee is rare in the northern State. It grows in masses on red, stony ridges around the black soil of the flats, up to 10 feet high as seen. Gidgee (Acacia Cambagei R. T. Baker) and Gastrolobium grandiflorum F.v.M. grow in the immediate neighbourhood. (Proc. Roy. Soc. N.S.W. xlvii, 235, 1913, as E. oleosa.)

Affinities.

It is a remarkable, narrow-leaved species, with narrow juvenile foliage, buds with long opercula of less diameter than the calyx-tube, and small fruits with well exserted awl-like tips to the capsules. It is not easy to indicate its closest affinity, showing that it is a strong species.

1. With E. uncinata Turcz.

It would appear to have affinity to E. uncinata Turcz., but Mr. Boorman, an experienced collector, is emphatic that the two species are very different in habit. E. Bakeri is a tree of 50 feet and even more, reminding one of a Willow; indeed, it was first sent in as “Willowy Eucalypt.” The foliage is narrow, and somewhat dull in appearance; the anthers are very similar, but not identical, while there is no kink in the filament in the stamens of E. Bakeri. (Original description.)

For E. uncinata turn to Plate 62, Part XIV. E. Bakeri has narrower leaves (as a very general rule), and narrower juvenile leaves; the anthers are different, though not widely so. The buds of the two species sufficiently resemble each other to necessitate caution, but the fruits are different.

2. With E. viridis R. T. Baker.

Drawings of E. viridis (under E. acacioides A. Cunn.) may be seen at figs. 9–12, Plate 52, Part XI of this work, and a larger drawing at Plate 180 Part XLVIII of my “Forest Flora of New South Wales.” The latter has fruits with thin rims and non-exsert valves.

3. With E. salmonophloia F.v.M.

Its fruits remind one of those of the Western Australian E. salmonophloia F.v.M., but those of the latter species are smaller, more shiny, have thinner and more marked pedicels. (Original description.)

For E. salmonophloia see Part XVII, Plate 73. It may be added that the latter is a larger timber tree, with smooth bark, and different anthers.

4. With E. Seeana Maiden.

E. Seeana Maiden is another species with small fruits (which are, however, domed), and a long operculum (more tapering into the calyx-tube in E. Seeana), leaves different, and the bark of E. Seeana is smooth. (Original description.) For E. Seeana see Part XXXII, Plate 132.

5. With E. redunca Schauer.

E. redunca Schauer var. angustifolia Benth., is another narrow-leaved, long operculumed form. It is from south-western Australia, and has no close affinity to the present species.

Other narrow-leaved species are E. angustissima F.v.M. and E. apiculata Baker and Smith, but they have no special affinity to this species. (Original description.) For E. redunca var. angustifolia see Part XXXIV, Plate 140.

6. With E. oleosa F.v.M.

E. oleosa F.v.M. bears an obvious resemblance as far as the fruits are concerned, but those of the new species are smaller, and in leaves and in most other respects the affinities are not obvious. (Original description.) It is amusing that, nevertheless, I should have first recorded the Jericho specimen as E. oleosa. For E. oleosa see Part XV, Plate 65. The latter species has, however, broad juvenile foliage.
