Hakea lorea, R.Br. 
A Western Cork-tree. 
(Family PROTEACEvE.) 
Botanical description.— Genus, Hakea. (See Part XLYI, p. 105.) 
Botanical description. —Species, H. lorea, B.Br., Proteaceas Novas, p. 25 (1830). 
A tall shrub or tree attaining 20 feet. 
Leaves terete, smooth, often above 2 feet long, and rarely under 1 foot, very rarely (on barren 
branches 1 on young plants ?) a few once or even twice forked or trifid. 
Racemes cylindrical, in the upper axils, sometimes forked or in a terminal cluster, more dense 
than in H. Cunninghamii, from under 3 inches to fully 6 inches long, the rhachis, pedicels 
and perianths densely pubescent with shorter hairs much less appressed than in H. Cunning- 
hamii. 
Perianth tube nearly four lines long, slightly dilated below the middle, revolute upwards. 
Torus oblique, but less so than in II. 0unninghamii. 
Gland large, horseshoe-shaped. 
Ovary stipitate ; style long, with a veiy oblique broadly stigmatic disk. (B.F1. v, 496.) 
In describing the plants of the Elder Exploring Expedition collected by 
Mr. It. Helms, Mueller and Tate say :— 
Hakea lorea , R. Brown. South Australia :—Arkaringa Valley and near Everard Range. 
Western Australia: —Cavenagh and Barrow Ranges. “ Cork-bark tree,” attaining to 20 
feet; bark corky, deeply fluted, three and a half inches at most, half an inch at least in 
thickness. ( Proc. Roy. Soc. S.A., xvi, 362.) 
In describing his Hakea suberea, S. le M. Moore gives it the synonym 
(H. lorea, Mueller and Tate, non B.Br.). 
He further says :— 
Specimens of the same tree were obtained by Mr. Helms of the Elder Expedition in the Cavenagh 
and Barrow Ranges. In the report of that Expedition these specimens are referred to Hakea lorea, R.Br., 
a course I find it impossible to acquiesce in, at the same time feeling doubts as to whether there can be 
authentic specimens of H. lorea at Melbourne. Two congeners more easily separable it would be scarcely 
possible to find. The chief differences lie in the shorter and slenderer leaves of II. suberea, its short, stout 
pedicels not longer than the perianths, the latter organs larger and much broader with a dilated base, the 
larger anthers, the bigger gland, subsessile ovary, and elongated stout style. Moreover, the distribution of 
the vascular scars left upon the stem after the fall of the leaves, a point to which Meissner attaches 
importance, is different in the two, II. suberea being, in this respect, more like II. Cunninghamii, R.Br. 
This tree was seen from the Black Gin soak, between Goongarrie and Mt. Margaret, northwards to 
our farthest point—some high granite rocks fourteen miles north of Lake Harlot. Wherever it occurs, 
subterranean water is supposed to be somewhere in the vicinity, and experience has so far, I believe, 
justified the supposition. 
My specimen—unfortunately only a single one and not very good—agrees perfectly with that of 
the Elder Expedition in the Kew Herbarium. ( Journ. Linn. Soc. Bot., xxxiv, 224.)
