The biogeography of the species in the series seems to indicate narrow endemism with an Andean center of diversity and limited dispersal to Central America. As such, we hypothesize that both concepts represent separate, morphologically distinct, geographically isolated populations. Ecologically, both species are reported to occur as epiphytes around or below
