from Stilpnogyne in all the achænia bearing pappus; from 
Erechthites in the achænia not being rostrate, in the pappus 
being rough, in the florets of the ray not being toothed, and 
in the branches of the style not being terminated by a cone ; 
and finally, from Cremocephalum in the involucrum not being 
many leaved and calyculate, the achænia not being ribbed, 
and the receptacle not being fringed and thickened at the 
base. It is possible, however, that some of the plants doubt- 
fully referred by DeCandolle to Kleinia may belong to the 
same genus, especially his K. acaulis and subradiata. 
It may be named Ceradia, in allusion to the horned appear- 
ance of its branches, and thus defined.
