Extreme examples are very distinctive and the leaves retain the sericeous indumentum until they are old, but the character is very variably expressed and, coupled with the scattered occurrence of this taxon, recognition as a forma is most appropriate in order to provide a name for a cultivated plant. Semple (1970b) claimed that the character is not genetically fixed; this might be true, but the ability to produce it probably is under genetic control, since the vast majority of plants never develop it and those that do are found in only a limited part of the species’ total range.

Distribution and Ecology: Fig. 136). Scattered throughout most of the northern part of the range of the species, on both Atlantic and Pacific coasts, but most common in the West Indies and Florida (not in Bermuda [Britton, 1918]); south to Bahia on the Atlantic coast and to Ecuador on the Pacific coast. If the type was collected in Pernambuco it would be only the second Brazilian and fourth continental South American record known to me. Semple (1970b) mapped it extending south only to the Honduras/Nicaragua border on the mainland and southern Jamaica and Cuba on the islands, except for one locality on Grenada. Bornstein (1989), however, stated that most plants from the Lesser Antilles have sericeous young parts, but this is not confirmed by my examination of many specimens. This taxon is nevertheless probably greatly under-recorded. Cultivated in at least Dominican Republic, Florida, and Hawaii.
