Botanical description.

— Species, E. Bosistoana, F.v.M., in Australasian Journ. Pharm., 1895.

Finally tall; branchlets slender, at first angular.

Leaves. — On rather short petioles, almost chartaceous, mostly narrow or elongate-lanceolar, somewhat falcate, very copiously dotted with translucent oil glandules, generally dull-green -on both sides, their lateral venules distant, much divergent, the peripheric venule, distinctly distant from the edge of the leaf, all faint.

Leaves. — of young Seedlings.-Roundish or ovate, scattered, stalked; umbels few-flowered, either axillar-solitary or racemosely arranged.

Peduncles. — Nearly as long as the umbels or oftener variously shorter, slightly or sometimes broadly compressed.

Pedicels. — Usually much shorter, rather thick and angular.

Tube of the Calyx. — Turbinate-semiovate, slightly angular.

Lid. — Fully as long as the tube, semiovate-hemispheric, often distinctly pointed.

Stamens. — All fertile, the inner filaments abruptly inflected before expansion; anthers very small, cordate or ovate-roundish, opening by longitudinal slits.

Style. — Short; stigma somewhat dilated.

Fruit. — Comparatively small, nearly semiovate, its rim narrow, its valves 5–6 or rarely 4, deltoid, totally enclosed, but sometimes reaching to the rim; sterile seeds very numerous, narrow or short; fertile seeds few, ovate, compressed, slightly pointed.

In swampy localities at Cabramatta and in some other places of the County of Cumberland, and also in the County of Camden (Rev. Dr. Woolls); near Mount Dromedary (Miss Bate); near Twofold Bay (L. Morton); near the Genoa (Barnard); on the summit of the Tantawanglo Mountains, and also near the Mitchell River (Howitt); between the Tambo and Nicholson Rivers (Schlipalius); near the StrezIecki Ranges (Olsen). The "Wul Wul" of the aborigines of the County of Dampier; the "Darjan" of the aborigines of Gippsland. Called locally by the colonists of New South Wales Ironbark Box-tree, and in some places also Grey Box-tree, which appellations indicate the nature of the wood and bark, though the latter may largely be shedding.

As richly oil-yielding, and also as exuding much kino, this tree is especially appropriate to connect therewith the name of Joseph Bosisto, Esq., C.M.G., who investigated many of the products of the Eucalypts, and gave them industrial and commercial dimensions.

This species, in its systematic affinities, is variously connected with E. odorata, E. siderophloia, E. hemiphloia, and E. drepanophylla. A fuller account of this valuable tree will early be given. (Op. cit.)

Shortly after the publication of E. Bosistoana, I wrote to Baron von Mueller, pointing out that he had confused two trees in his description, namely, a "Grey Box" and an "Ironbark Box." He thanked me for the information, and stated he intended to publish further notes on the tree (as, indeed, he promised at the conclusion of the description), but his intention was frustrated by pressure of work, and subsequent death.
