Three new Buxus species (Buxaceae) from eastern Cuba

摘要

Three Cuban species of the genus Buxus, endemic to the Sierra de Moa-Baracoa mountain system, are described as new to science. Besides morphological descriptions, the results of a character analysis including pollen morphology, leaf venation and leafanatomy are presented, which contribute to the delimitation of the species and the clarification of their relationships.
