Discussion:

This species is known by its branch leaves with green cells broadly triangular in section and adjacent hyaline cell walls ornamented by comb fibrils. The comb fibrils are sometimes conspicuous and at other times scarcely developed, but they can usually be detected at the leaf insertions. Flatberg (1984) has referred the Belize material, as well as collections from Guatemala and Cuba, to subsp. affine (Ren. & Card.) Flatb., but I see no reason to subdivide the species in its more inclusive, traditional sense.
