Orchids from the Greater Antilles I: a new species of Bletia

Bletia antillana (Orchidaceae), a species restricted to eastern Cuba, is described and illustrated. This species is similar to Bletia purpurea but differs by the following: 1) the leaves always present during anthesis; 2) flower is semi-erect; 3) flower parts larger; 4) dorsal and lateral sepals straight; 4) petal curved, enclosing the column and the lateral lobes of the lip; 5) lip whitish at base, rose-purple at the apex of the lateral lobe, and yellow at the callus; and 6) lip obovate, with a quadrangular midlobe curved downward.
