Abstract

Bunchosia quaesitor has inflorescences terminating main axes, a characteristic unique to this endemic to southwestern Haiti. Bunchosia pauciflora from northern Haiti was confused by Niedenzu with B. haitiensis Urban & Niedenzu, but B. haitiensis is two-carpellate with a glabrous ovary and connate styles, and B. pauciflora is three-carpellate with a pilose ovary and distinct styles. Bunchosia articulata, endemic to Cuba, is distinguished from its closest relative, B. swartziana Griseb., by its petals with glandular limb margins, basally articulated peduncles, and elliptic leaf blades. Bunchosia macilenta, from Bahia, Brazil, can be divorced from Bunchosia acuminata, another new species from the same region, by its smaller, more meagre inflorescences with fewer flowers and smaller leaves with 4-6 abaxial glands. Bunchosia systyla (Niedenzu) Dobson was originally described as a form of B. fluminensis (Griseb.) Griseb. but is given species status here.
