Abstract

Hitherto “suppressed,”Cacao guianensis, based on a mixture of elements that can be referred to three currently recognized species (i.e.,Theobroma cacao, T. subincanum, andT. velutinum), is lectotypified by Aublet's illustrations of its flowers. This makesC. guianensis a taxonomic synonym ofT. cacao and encourages nomenclatural stability by permitting the continued use ofT. subincanum andT. velutinum.
