294 MR. S. MOORE ON THE FLORA 
phylla longe post anthesin coherentia, 12 em. long., lobi antheri- 
feri alte exeavati, 025 em. long. Ovarii stipes 0°15 em. long. 
Stylus crassus, deorsum 0:1 em. diam., L7 cm. long. Stigma 
obliquum, conieum, rugatum. 
Specimens of the same tree were obtained by Mr. Helms of 
the Elder Expedition in the Cavanagh and Barrow Ranges. In 
the report of that Expedition these specimens are referred to 
Hakea lorea, R. Br., a course | 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 H. 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, H. suberea being, in 
this respect, more like H. Cunninghamii, R. Br. 
This tree was seen from the Black Gin soak, between Goon- 
garrie and Mt. Margaret, northwards to our farthest point— 
some high granite rocks fourteen miles north of Lake Darlöt. 
W herever it occurs, subterranean water is supposed to be some- 
where 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 iu the 
Kew Herbarium.
