AUSTRALIAN PLANTS. 39 



tf 



covered with a velvet-like indument ; leaves approximate, simple, ovate 

 or subcordate, blunt, sessile, with revolute margins ; flowers tetran- 

 drous, axillary, solitary, on short pedicels, forming at the end of the 

 branches a foliate raceme; sepals acute, lanceolate, half as long as the 

 corolla ; filaments hispid ulous ; carpels elliptico-oblong, compressed, 

 pubescent. 



Hab. In sandy places about Encounter Bay and in Kangaroo Island. 

 By this interesting species the genus Zieria becomes united with 

 Boro7ua, to which I am also inclined to refer Cyanothammis. 



XIII. Celasteineje. 



48. Celastras Au$tralis^ Harv. and Muell. ; climbing; branches 

 warted; leaves glabrous, lanceolate-acuminate, crenate or repand-ser- 

 rated, their teeth mucronulate ; panicles terminal ; capsules three- 

 valved, cells one- or two-seeded. 



Hab. On the Snowy and Buchan Rivers, not only on rich ground, 

 but also on rocks. 



The first Australian species described of this genus, resembling 0. 

 paniculatus and C. dependens, from East India. 



XIV. Ehamne^e. 



49. Try mtilmm pMeioj^Ii^lhmy'F, MuelL ; branches thickly clothed 

 with velvet hairs ; leaves coriaceous, oval or roundish-ovate, blunt or 

 retuse, perfectly glabrous above, and densely net-veined, grey-silky be- 

 neath, their margins generally reflexed ; stipules lanceolate, acuminate ; 

 glomerules disposed in cymes, tomentose; carpels indehiscent. 



Hab. On the rocky summits of the Elders* Eanges, and other 

 mountains near Lake Torrens. 



Easily recognized by the numerous prominent, anastomosing veins 

 of the leaves. Length of the leaves, quarter to half an inch. 



50. Tiymalium bilobatum, F. Muell. ; branchlets subvelutinous ; 

 leaves herbaceous, wedge-shaped, with a dilated, bilobed summit, the 

 margins flat or revolute, glabrous above, thin velvety beneath, their 

 lobes truncate, denticulate, the notch apiculate; stipules lanceolate- 

 subulate ; umbels somewhat velvety, crowded at the summit of the 

 branches; style three-cleft; carpels bursting at the base. 



Hab. On dry scrubby ridges towards Guichcn Bay, and on Spencer's 

 Gulf.
