 obtusis, ad apicera pilosiusculis. Corollae tubulosee, gla-

 Styli rami longi exserti. Acheenia acute 5-angulata, gla-

Although this and the succeeding species differ in some 

 minor points from the one on which De Candolle founded 

 the genus, they are not of sufficient importance to constitute 

 a generic distinction. In the present species the pappus is 

 reduced to a mere ring, but the presence of fine teeth 

 show a tendency to the production of setae. In the following 

 species the setae vary from 5 to 10, those corresponding to 

 the angles of the achaenium being the largest, while the inter- 

 mediate ones are either wanting altogether, or much smaller 

 than the others.
