Note Typical C. cubensis is Well distinguished from C. arctocarpus by the more elongate upper laminal cells and the long-excurrent, dentate costa. In the collections from the Guianas both characters show 21 broad Variation, which makes the separation difficult. Collections from the Pakaraima Mts. in Guyana include specimens with elongate upper lamina] cells and a rather short apex as Well as specimens with short upper laminal cells and a long-excurrent, sharply toothed costa. The distribution of C. cubensis is mainly Caribbean and C. arctocarpus is Widespread in the Neotropics (Frahm & Gradstein 1987). Frahm (199 l) Suggested that C. cubensis developed as a subspecies of C. arctocarpus by isolation on the Caribbean Islands.
