CCLV. E. odontocarpa F.v.M.

In Journ. Linn. Soc., iii, 98, (1859).

FOLLOWING is a translation of the original:—

A shrub with angled branchlets; leaves opposite, rather shortly petiolate, linear or narrow-lanceolate, sub-falcate, acute at the base, shining, covered with bright dots, penniveined and reticulately veined, peripheral vein slightly distant from the margin; umbels axillary, not exceeding three flowered, shortly pedunculate; the obconical acute quadridentate tube of the shortly pedicellate calyx three times as long as the depressed hemispherical operculum; fruits ovate-obconical indistinctly costate, quadridentate, trilocular, valves inserted below the margin.

In sandy desert near Sturt's Creek, flowering in autumn.

Shrub of 8–10 feet. Branches rather slender. Leaves 2–5 inches long, 3–6 lines broad. Umbels sometimes two, one of the depauperate. Fruits 3–4 lines long, shining.

It was next described in English by Bentham, in B.Fl. iii, 260:—

A shrub of 8 to 10 feet, with slender branches (F. Mueller). Leaves opposite or alternate, linear-lanceolate, mostly 3 to 5 inches long, with oblique anastomosing veins, inconspicuous at first, more prominent in the fruiting specimens, the intramarginal one near the edge. Peduncles axillary, short, each with three small flowers on short pedicels, but not seen expanded. Calyx-tube in the bud narrow-turbinate, about 2 lines long, with four small, but prominent, spreading teeth. Operculum hemispherical, very obtuse. Stamens apparently not in clusters; anthers small, with parallel cells. Fruit oblong-cylindrical, 4 to 5 lines long, not contracted at the orifice when fully ripe; rim narrow, concave, the capsule slightly sunk, three or four celled.

It was not included in the “Eucalyptographia,” but under E. tetrodonta it is stated that well developed flowers (of E. odontocarpa) are unknown.

Range.

On a drawing of a portion of the type the words “Sturt's Creek, Desert, February, 1856, Ferd. Mueller.” This is in the Northern Territory, in about 18 degrees south latitude.

It also occurs in north West Australia (West Kimberley), also in desert.

Northern Territory

“Small tree (Mallee).” Tanami Goldfield. (Dr. H. I. Jensen; C. E. F. Allen's No. 202.)

Western Australia

“Desert south of Fitzroy River, West Kimberley.” (W. V. Fitzgerald.)

This is one of Mr. Fitzgerald's labels, and his discovery of this species as new to Western Australia does not appear to have been recorded. It will be observed that, like Mueller, he speaks of it occurring in a “desert.”

Affinities.

1. With E. eudesmioides F.v.M.

E. odontocarpa is “very much like some specimens of E. eudesmioides, but the stamens do not appear to be arranged in clusters.” (B.Fl., iii, 260.)

The affinities of the various species of the Eudesmieæ are dealt with at p. 137. The morphology of the filaments in the various species is discussed separately at p. 135.

2. With E. tetrodonta F.v.M.

E. odontocarpa “… at once distinguished from the following species (tetrodonta) by the very much smaller flowers.” (B.Fl., iii, 260.) Luehmann (Proc. Aust. Assoc. Adv. Science, vii, 524) thought E. odontocarpa is probably a variety of E. tetrodonta. The species are compared to some extent in the table at p. 137.

3. With E. tetragona.

E. tetragona is through E. eudesmioides also cognate to E. odontocarpa, of which well-developed flowers remained as yet unknown; the differences of the latter consist in still narrower and somewhat curved leaves with more spreading veins, in the smallness of its flowers with proportionately more developed calyx-teeth, and the not membranously margined seeds; very possibly its anthers will bring it nearer to E. tetrodonta.” (“Eucalyptographia.”)

See the table at p. 137. E. tetragona and E. eudesmioides will be dealt with in Part XLVI.
