    Pithecellobium latifolium (Linnaeus) Bentham subsp. tayronense Barbosa, Caldasia 14: 397. 1986. — "COLOMBIA, Magdalena, Santa Marta, Parque Nacional Natural Tayrona, ‘El Cedro,’ alrededores de la quebrada El Cedro, 350-900 msnm, 21 Jun 1983 C. Barbosa, G. Lozano, S. Díaz & E. Barrera 1863 fl." — Holotypus, COL!. — Several approximate topotypes cited have not been verified, but H. H. Smith 929 (NY), annotated by Barbosa as P. latifolium and cited as subsp. tayronense, are here referred to Z. latifolia var. communis.

    As described for the species, and differing consistently from more widely dispersed var. communis only in pod at least 1.7 cm, usually 2 cm wide or wider; lfts broadly ovate to lance-elliptic, but never more than 5 per pinna.

    In moist or flooded woodland, entering the margin of mangrove swamps and ascending inland to ±400 m, discontinously dispersed in lat. 20°N-2°S; SE Mexico (Tabasco); around the Caribbean basin on the Greater Antilles (E Cuba, E Jamaica, SW Haiti), Lesser Antilles (S from Martinique), E Panama and adj. Colombia, Trinidad, thence S in South America, along and near the coast, from the Orinoco delta through the Guianas to the Amazon delta and N Maranhão. — Map 36. — Flowering nearly throughout the year. — Hoopwood; horsewood (Jamaica); cacolay (Grenada); maya-maya (Honduras).

    We have found nothing of substance to distinguish subsp. tayronense, either in the protologue or in the holotype. The larger leaflets of the latter are about 13 cm long, and its pod is 17 x 2.8 cm, well within the limits of variation recorded for Z. latifolia var. latifolia.
