Astelma is now first detached from Gnaphalium by the 

 above able band ; and founded upon the present species 

 characterised as a genus by a naked receptacle of t/ie flower. 

 (neither chaffy nor honeycombed) ; a sessile feathered seed- 

 crown, the radii of which are connected at the base; an 

 imbricated calyx composed of scariose leaflets, the inner- 

 most of which are convergent, and whose florets are all 

 both stamen-bearing and pistil-bearing. It is the nearest 

 genus to Elichrysum, from the genuine species of which, 

 according to Mr. Brown, it only differs by the rayless calyx.

It is said to be in several collections, and to have been 

 generally conceived to be Dendrobium Pierardi of the 

 unedited part of Roxburgh's ' Flora Indica' ; and which, 

 according to Mr. Brown, to whom, as in so many instances, 

 we are indebted for all we have to say on the subject, it is 

 possible it may really be ; but finding by both figure and 

 description the flowering stems of that species represented 

 as leafless, the lamina of the labellum of an obovate form, 

 and leaves as emarginate, while in the present plant the 

 flowering stems are in full leaf, its labellum of an ovate 

 outline, and the leaves taper-pointed, he has deemed it safer 

 to regard the present sample as belonging to a distinct 

 species.
