38 TLORA OF SOUTH AMERICA AND THE PACIFIC. 



the involucre, together with the greater size and breadth of 

 the inner scales, will readily distinguish this species. The 

 male capitula, as De Candolle justly remarks, are small, 

 almost globose and drooping, very much resembling some 

 species oi Artemisia; those of the female plant are larger, erect, 

 with long tawny pappus.

 plants the pappus of the female flowers is longer than the in- 

 volucre, and the capitula are often pedicellate.
