Distribution.

Southern Mexico to Costa Rica, and in western Cuba. A collection stated to be from St. Lucia (the type of Belotia caribaea ) represents either material cultivated in the St. Vincent Botanic Garden or mislabeled material from Cuba ( Bornstein 1989: 185-186).

Note.

The name Trichospermum grewiifolium (A. Rich.) Kosterm. is frequently applied to this species, but it is illegitimate because as explained in the text Belotia grewiifolia A. Rich. was nomenclaturally superfluous when published ( McNeill et al. 2006: Art. 52.1) and cannot serve as the basionym for this combination. More recently, Rodríguez Fuentes (2000: 32) accepted Trichospermum grewiifolium as a new species published by Kostermans (1962) apparently in the belief that Kostermans had explicitly excluded the purported basionym’s type, but this is debatable and in any case Trichospermum grewiifolium is not a valid name as Kostermans failed to designate a nomenclatural type ( McNeill et al. 2006: Art. 37.1).
