The genus Rhysolepis (from pvods, wrinkled, and Aezis, scale) 
is related on the one hand to Sclerocarpus Jacq., next to which it 
may be inserted, and on the other to Viguiera HBK. From the 
former it differs essentially in the presence of a pappus and some- 
what in habit, from the latter in the firm enclosure of the achenes 
and base of the corollas by the much larger transversely wrinkled 
pales. From its general characters and its pappus, which are 
essentially those of Viguiera, it seems to be a comparatively modern 
derivative of that genus, while Sclerocarpus, from its distribution, 
must be considered an ancient genus whose progenitor has long 
since disappeared.
