CCXLV. E. similis Maiden.

In Proc. Roy. Soc. N.S.W., xlvii, 90, (1913).

FOLLOWING is the original description:—

Arbor mediocris. Folia juvena tenua, glabra, pedunculata, ovato-acuminata. Folia matura angusto-lanceolata, flavo-virentia, concoloria, circiter 12 cm. longa, 2 cm. lata. Venae laterales, pinnatae distinctae, vena peripherica distincta et a margine remota. Umbellae confertae, multiflorae, plerumque in panicula terminale corymbosaque. Calycis tubus irregulariter costatus. Operculum hemisphæricum vel umbonatum. Fructus vix 1 cm. longi, truncato-ovoidei, in orificium sensim contracti.

A tree of medium size; notes on bark and timber uncertain.

Juvenile foliage.—Thin, parchment-like, perfectly glabrous, not seen strictly opposite, pedunculate, ovate-acuminate. Size of a specimen, 6 by 3 cm.

Mature foliage.—Narrow-lanceolate or slightly falcate, petiolate, the petioles flattened and twisted, length of blade up to 12 cm. and more, with a greatest width of about 2 cm. Equally yellowish-green on both sides, rather shiny, venation distinct, and nearly as prominent on the upper as on the lower side. Midrib very prominent, lateral veins pinnate and very distinct, the intramarginal vein distinct and removed from the edge.

Buds and Flowers.—Inflorescence profuse, in a loose umbel, several-flowered, mostly in a terminal corymbose panicle, the peduncles slightly compressed or angular, calyx-tube irregularly ribbed, shiny; opercula hemispherical or umbonate, shiny. Filaments yellow, anthers with long, narrow adnate cells, with a moderately large gland at the back, and the filament attached half-way up.

Fruits.—Sharply separated from the short pedicel, on a slightly flattened common peduncle of about 1·5 cm. Truncate-ovoid, gradually constricted towards the orifice, barely 1 cm. long and about 6 mm. at the orifice. Three-valved, the valves blunt, and these capsule teeth not adherent to the calyx-tube.

(In the above description two errors have crept in. The intramarginal vein is not removed from the edge, or, at most, only occasionally, and then only to a brief distance. The description of the calyx-tube as “irregularly ribbed” is a slip of the pen. The words should have been applied to the fruits. See figure 3e, Plate 182.)

The seeds are not winged.

Range.

It is confined to rather dry country in Central Queensland, so far as we know at present. The type came from “Desert country west of Emerald,” so described by Mr. G. H. Carr, Crown Lands Agent, Clermont, through Mr. R. Simmonds (March, 1908).

Many years previously I had received it from Jericho (Henry Deane), with fruits larger and more elongated than those of the type.

I have received it since from Mr. W. Pagan (through Mr. C. T. White) from the vicinity of Alice, a railway station 328 miles west of Rockhampton, or 21 miles west of Jericho, at no great distance from the type locality. Publication of the drawings will enable our friends in Queensland to greatly extend its range, since there is no doubt that it has been confused in the past with other Yellow-barked Bloodwoods or Yellow Jackets.

Dr. H. I. Jensen calls it “Desert sandstone Yellow Jacket,” and describes it as between a Bloodwood and Stringybark, with a very yellow bark.

Affinities.

Its closest affinity (at the time of description), appeared to be E. Baileyana F.v.M. (See description amended by me in “Forest Flora of New South Wales,” Part XXXV, 71). Like that species, it is a member of the section Eudesmieæ, and appears to differ from E. Baileyana in the following characters:—

1. E. similis is a “Yellow Gum,” “Yellow Jack” or “Yellow Jacket,” while E. Baileyana is a “Black Stringybark.”

2. The mature leaves of E. similis have the same colour on both sides, and have shorter peduncles, while the juvenile leaves are glabrous, those of E. Baileyana being covered with stellate hairs.

3. The fruits of E. similis are, in comparison with those of E. Baileyana, almost spherical to cylindroid, those of E. Baileyana being almost spherical, darker, and much larger.

The specific name is given in view of the affinity of this species to E. Baileyana F.v.M. (Original description, slightly amended.)

Its relations to the other members of the Eudesmiæ will be further referred to in Part XLV when the Eudesmiæ are all figured. See also under E. lirata, p. 111.
