In Journ. Roy. Soc. N.S.W., lii, 457 (1918), with Plates XXXVIII and XXXIX.

FOLLOWING is the original description:—

Arbor umbrosa in altum pedes quinquaginta crescens, trunci diametrum duorum pedum habens.

Folia matura.—Linearia lanceolata, a septem ad quatuor decim cm. longa, a septem mm. ad 1·4 cm. lata, cum apice directo vel falcato, utrobique aequaliter viridia, glabrosa et notabile nitida, aliquanto coriacea, costa media modice clara, venae laterales aliquanto obscurae et angulis 7–15° e costa media dispositae, margines quasi nervi sunt, olei glandulae numerosissimae petiolum 1–1·3 cm. longum.

Gemmae.—Sessiles, operculum acutum, longae circiter a tria ad quatuor mm. gemmae vix tam longae quam calycistubus, racemus stellatus, pedunculum longum circiter unum mm.

Flores.—In umbella tenus undecim antherae parvae, color ut lactis flos, versatiles, renantherosi.

Fructus.—Sessiles, globosi-truncati, fusci, nitidi quasi fuscati, interdum punctis parvis palladis clavati, longi a quinque ad sex mm. diametrum quinque sexve mm. habentes apud os restricti, labrum interius unum mm. crassus valve depressae.

Cortex—Levis et alba nisi quod squamus paucas asperes apud basem habet.

Habitat.—Summum jugum montis “Buffalo” prope casam ad provinciam “Victoria” pertinentem, in formationem siliceam graniteam quatuor millia et quadringenti pedes super mare nascens.

An umbrageous tree reaching 50 feet high, with stem diameter of 2 feet.

Seedlings.Hypocotyl erect, terete, red, glabrous, up to 2·3 cm. long.

Cotyledons obtusely quadrilateral to orbicular-reniform, entire, about 3 mm. long, 5 mm. broad, upper side green, under side red to reddish-green, glabrous; petiole about 3 mm. long.

Seedling foliage opposite, entire, glabrous, oblong-lanceolate to elliptical-lanceolate, petiole 1–2 mm. long; midrib prominent on underside, lateral veins fairly distinct, and arranged at angles of from 40–60 degrees with the midrib. On seedlings 5 inches high the second pair of leaves were elliptical-lanceolate, and up to 2 cm. long by 8 mm. broad, while the sixth pair were elliptical, and 2·5 cm. long by 1 cm. broad.

Mature leaves linear-lanceolate, from about 7–14 cm. long, 7 mm. to 1·4 cm. broad, with straight or hooked point, equally green on both sides, glabrous and remarkably shiny, somewhat coriaceous, midrib fairly distinct, lateral veins rather obscure, and arranged at angles of from seven to fifteen degrees with the midrib, margins nerve-like, oil glands very numerous, petiole 1–1·3 cm. long.

Buds sessile, operculum pointed, about 3–4 mm. long, scarcely as long as the calyx-tube, the cluster stellate, peduncle about 1 mm. long.

Flowers up to eleven in the umbel. Anthers small, creamy-white, versatile, renantherous.

Fruits sessile, globular-truncate, brown, shining as if varnished, sometimes studded with small pale dots, 5–6 mm. long, 5–6 mm. in diameter, restricted at the orifice, inner rim 1 mm. thick, valves sunk.

Bark smooth and white except for a few rough flakes at the base.

This species is named in honour of the late Sir Thomas Livingstone Mitchell, Surveyor-General, who collected many native plants, and was the second explorer to pass Mount Buffalo.

Summit of Mount Buffalo, Victoria, near the Government Chalet, growing in siliceous granite formation at 4,400 feet above sea-level, and known as Willow Gum. The species flowers in December.

So far as we know, it is confined to Victoria, but it is hardly reasonable to suppose that it will not be found on the adjacent high mountains (e.g., Mount Kosciusko) in New South Wales, and also in other elevated situations in Victoria.


1. With E. vitrea R. T. Baker.

From this it differs somewhat in its leaf venation, for the prominent, almost parallel veins of E. vitrea are not represented in this new species. The pedicellate hemispherical fruits of E. vitrea are also different; the operculum of that species is shorter and more obtuse, while the peduncle is very much larger. The bark of the new species is smooth and white, that of E. vitrea being fibrous over the greater part of the trunk.

2. With E. nitida Hook. f.

From this it differs in its more globular fruits, pointed instead of obtuse buds, and is an umbrageous tree, while E. nitida is only a tall shrubby plant.

3. With E. stellulata Sieb.

It resembles this species in its stellate buds and to some extent in the shape of its fruits, but differs in its leaf venation, colour of bark which is white, while that of E. stellulata is slate-coloured, and in its seedling foliage.

4. With E. Moorei Maiden and Cambage.

Its resemblances and differences are similar to those mentioned in the case of E. stellulata, and in addition E. Moorei only grows as a Mallee-like shrub of about 10–12 feet high.
