[Eucalyptus. 
round pores. Stigma somewhat dilated. Ovary flat-topped. Fruit rather small, 
semiovate, with a narrow compressed fragile occasionally somewhat indented 
margin, 8 to 4 or rarely 5-celled, valves not exserted, very short. — F. v. M. l.c. 
Hab.: Southern parts. 
I have no sample of the wood, but it is described by F. v. Mueller l.c. as very durable, and 
of a reddish tinge, close-grained, hard and tough. The large trees are said to be frequently 
pipey. The wood is used in the southern colonies for naves and felloes. 
16. E. populifolia (Poplar-leaved), llook. 1c. El. t,. 879 ; F. r. M. Eucalypt. 
Dec. 8. Poplar Box. “ Mullet,” St. George, Wedd. Usually a small tree, with 
wrinkled somewhat fissured persistent hark on trunk and branches, the foliage 
dense and glossy. Branchlets slender. Leaves 2 to 4in. long, scattered, orbicular- 
ovate or roundish, very glossy and deep green on both sides, occasionally verging 
into an oval-lanceolate form ; veins very spreading, not crowded, the intramarginal 
one distant from the edge ; oil-dots copious. Petioles usually long. Umbels 
paniculate, mostly terminal, some lower ones singly in the axils of the leaves. 
Flowers in each umbel from 8 or 4 to 14, small, very shortly pedicellate. Calyx- 
tube almost semiovate, slightly longer than the nearly hemispherical operculum. 
Stamens much inflected in the bud, all fertile. Anthers roundish-ovate, opening 
below the summit by pores or abbreviated slits. Style very short, stigma some- 
what dilated. Fruit very small, semiovate, 4-celled or sometimes 8 or 5-celled; 
valves very short, situated close beneath the rim. Seeds minute. — F. v. M. l.c. 
Hab.: Met with generally inland from the southern border to the Burdekin River, and islands 
of the Gulf of Carpentaria. 
Wood of a grey or light-brown colour, very tough and strong, hard to work, but is a handsome 
wood when polished ; used in house-building, dray-poles, and ship-building. — Bailey’s Cat. Ql. 
Woods No. 183. 
F. v. Mueller, Eucalypt. Dec. 3, says that the variety parviflora of E. bicolor, mentioned in 
FI. Austr. iii. 215, belongs to this species. Hab : Burdekin River, F. v. Mueller. 
17. E. ochrophloia (yellow bark), F. v. M. Fragm. xi. 36. Yellow 
Jacket. “ Yapunyah,” Bulloo River, J. F. Bailey. A tree usually about 40 or 
50ft. high, with a rather thick spongy brownish-yellow bark; branchlets slightly 
angular. Leaves thick, glossy on both sides, oblong-lanceolate or falcate, 4 to 
6in. long and A to lin. broad, somewhat unequal at the base, lateral nerves some- 
what patent, the intramarginal distant from the edge, oil-dots copious. Umbels 
axillary, solitary or crowded in corymbs. Calyx-tube with pedicel about lin. long. 
Operculum acutely conical, abouc 3 lines long. Stamens indexed in the bud, the 
outer ones without anthers. Anthers cordate or reniform, often truncate, slits 
irregular. Style shorter than the stamens, stigma not thicker than the style. 
Fruit clavate-ovate, about ^in. long and scarcely over 3 lines thick, not angular, 
3 rarely 4-valved, margins of the orifice thin, taller than the valves. Seeds 
scarcely A line long. 
Hab.: Paroo, Cunnamulla, and other inland localities. 
Wood of a brownish colour, hard, heavy, and close-grained. — Bailey’s Cat. Ql. Woods No. 180. 
18. E. bicolor (two-coloured), A. Cunn. Herb.; Hook, in Mitch. Trop. Austr. 
390; Benth. FI. Austr. iii. 214. A large shrub or sometimes a tree of 30 to 40ft., 
with a persistent ash-grey or blackish bark (F. v. Mueller, A. Cunningham / , or a

peduncles, the umbels forming usually axillary or terminal panicles shorter than 
the leaves. Pedicels shorter than the calyx. Calyx-tube turbinate, nearly 1A 
line long. Operculum rather thin, hemispherical, obtuse or umbonate, shorter
