Abstract

Portlandia proctorii (Rubiaceae, Catesbaeeae), a new combination for a narrow endemic Jamaican species. Brittonia 55: 233–239. 2003.—Aiello, in a revision of Portlandia and related genera, recognized two varieties in Portlandia coccinea Sw. based on leaf shape and geographic distribution. After detailed studies of herbarium specimens, recent observations of both varieties in their natural environment and in cultivation, and a phylogenetic analysis, it became evident that P. coccinea var. proctorii Aiello should be treated as a separate species with corollas shorter and of a different shape than those of var. coccinea. Portlandia proctorii is presented as a new combination. A key for the two species, descriptions and illustrations are included.
