I'lii> plant appears to stand near Eleutkeranthera, with which it 

 shares many characters. It differs, however, markedly in its anthers, 

 which an- appendiculate and connate, in its aon-accrescent involucre, 

 and densely puberulent achenes. Furthermore in Eleutkeranthera 

 the achenea have a nipple-shaped contracted summit which is here 

 lacking.
