Abstract
A new genus,Oldenlandiopsis, is proposed, based onOldenlandia callitrichoides Griseb., native to the West Indies, southern Mexico, and Central America. Relationships toOldenlandia andLucya, the latter with 6-aperturate pollen, are discussed. The major character differences between the new genus andOldenlandia are in pollen structure, chromosome number, capsule shape and dehiscence, and seed shape and number.
