208 AUSTRALIAN PLANTS. 



upright, tomentum white, shineless, not silky, leaves deeper divided 

 with distant segments, and flowers more numerous. 

 - 160. Gre\ii\e^ jfterosj}€rma (Sect. C]jcloptera\ F. MuelL; upright; 

 branches strict, holosericeous^ leaves glaucous, somewhat rigid, narrow- 

 linear, elongate, undivided or bitrifid, glabrescent, ending in a sphace- 

 late mucrone, above convex, and manifestly striated ; margins refract 

 to the middle nerve, which beneath is very prominent ; racemes alter- 

 nately crowded at the end of the branches, elongate, dense-flowered ; 



" calyx outside, with pedicels and rachis, grey-pubescent, inside, together 

 with the style, smooth ; gerraen stipitate, tomentose ; stigma, ovate, 

 oblique-terminal, centrally umbonate; foUiculi globose-ovate, turgid, 

 hardening, with short stipes, grey-tomentellous ; seeds flat, ovate, even, 

 all round winged with a thin membrane. 



• Hab. In the Mallee Scrub on sand-hills towards the junction of the 



Murray and Murrumbidgee. 



Allied to several tropical species, particularly to G. angustata (K-. Br» 

 Suppl. p. 24). 



161. Orites lancifoUa^ (Sect. Acroderru), F, Muell.; leaves oblong- 

 lanceolate, flat, glabrous, blunt, net-veined, perfectly entire ; spikes ax- 

 illary and terminal, sub-solitary ; calyx smooth ; germen silky-downy ; 

 foUicle silky. 



Hab. On the rocky summits of the Australian Alps, 5000-6000 feet 

 high ; for instance, on Mount Wellington, Mount Hotham, Mount La- 

 trobe, in the Munyang Mountains, in the upper valleys of the Mitta- 

 Mitta, etc. 



This fine shrub is, besides Grevillea Victoria, the only really alpine 

 species of this Natural Order, endemic, in the Australian continent. 

 But I am uncertain whether it may prove to be identical with 0. Mil- 

 liganij of which no description has been hitherto given.

longer than their lamina ; style tripartite.
