nearly dry or fleshy ; pyrenes smooth orribbed. Seeds solitary ; radicle 
inferior.—Small shrubs with opposite leaves, ample usually bidentate 
stipules and rather small flowers crowded in terminal and axillary 
pedunculate or rarely sessile involucrate heads. 
A considerable tropical genus, chiefly American. According to the usual prin- 
ciples of nomenclature, one of the names of Aublet, quoted by Bentham and Hooker, 
ought to be employed for this genus in preference to Swartz’s; a still older name 
however, is Ouragoga, Linn. Gen. PL, edit. i., p. 378 (1737).
