124 ili?'. Brown's Oliset'valiomt on the 



Leontopodioides, which may be called Leontopodium, is in afli- 

 nity intermediate between Antennaria and Gnaplialiuiu as here 

 limited, but has sufficient characters to distinguish it from both. 



The third tribe has been found only in South Africa, and con- 

 sists of shrubs with small rigid heath-like leaves, of which the 

 niaro'ins are incurved, the upper surface tomentose, and the un- 

 der convex and nearly smooth ; but by a remarkable twisting 

 they are in most of the species resupinate ; a character which 

 seems to have been overlooked in all the described species; 

 namely, GnaphaUum muricatum, miicronatum, and scripliioides. In 

 this tribe, or genus, which may be named Metalasia, the invo- 

 lucrum is generally cylindrical, and in most of the species has a 

 short radius formed by the spreading coloured laminae of the inner 

 scales; the flosculi are few in number, and all hermaphrodite ; 

 and the radii of the pappus, which fall oif separately, are either 

 thickened or more strongly toothed at top. 



Galea pinifolia does not even belong to this genus, though it 



has a nearly similar habit ; but the margins of its leaves are revo- 



lute, and their toinentum chiefly on the under surface. In these 



respects, as well as in the principal characters of fructification, it 



agrees with several shrubs, chiefly of New Holland and Van 



Diemen's Island ; among which are Eupaloriianferri/giueiim, Eu- 



patorium rosmarinifolium, and Chrysocoma cinerea of M. Labillar- 



diere. Part of these have the inner squamas of the involucrum 



simple, as seems to be the case in Galea pinijolia ; while in others, 



as the two species referred to Eupatorium by M. Labiilardiere, 



they form a short radius. These I am inclined to consider merely 



sections of one and the same genus, which may be distinguished 



by the following character, and named 



OZOTIIAMNUS.
