 ovate-oblong leaves commonly subcordate, the corolla in bud globular and its

 if so, it must belong to the coast districts, il/. Fraseri, Decaisne in DC. Prodr. 

 viii. 513, may belong here. It was described from a specimen in Bentham's 

 herbarium, received from that of Forsyth, and thought perhaps to come from 

 Carolina, but most probably from the West Indies.
