This plant appears to stand near Eleutheranthera, with which it 
shares many characters. It differs, however, markedly in its anthers, 
which are appendiculate and connate, in its non-accrescent involucre, 
and densely puberulent achenes. Furthermore in Lleutheranthera 
the achenes have a nipple-shaped contracted summit which is here 
lacking.
