Discussion:Previous workers have divided the Cuban material of Tapura into three species, T. cubensis, T. obovata, and T. orbicularis. The latter species is quite distinct, but the other two do not differ significantly. There is a complete gradation between T. cubensis and T. obovata which was separated mainly by leaf shape. However, within T. cubensis there is a large variation in leaf shape and size. Some collections from Oriente Province are much more distinct than is T. obovata. This material is separated here into a subspecies. It may ultimately prove specifically distinct, but I hesitate to describe another new species from Cuba when most of the existing herbarium material is sterile.

The following sterile material is intermediate between T. cubensis subsp minor and T. orbicularis. CUBA. Oriente: Alain & Lopez 4878 st (GH). Isla de Pinos: Roig & Clemente 1818 st (NY). Pinar del Rio: Lörs 4789 st (NY).

Baillon (1886) described a variety of T. cubensis, var wrightiana. This variety does not differ significantly from T. cubensis, and is considered here as part of subspecies cubensis.
