This plant has been confused with the Jamaican P. oblongata by
Masters and others. As Urban points out, the shorter calyx tube,
the erect (not dependent) operculum, much shorter petioles, and the
fact that the flowers are not in
separate P. cubensis from its near relative.
a raceme-like inflorescence readily
In Wright 198a and Shafer 871 the leaves are scarcely lobed;
the flowers, however, appear to be identical with those of typical
P. cubensis. In Shafer 3772 the leaves are deeply bilobate, resembling
forms of P. ornithoura.
