This study reports the widespread occurrence of foliar nectaries in most New World species of the genus Cyathea. The anatomy of these glands and the variation in structure among the species is described. Some Cyathea species primitively lack glands, and the presence or absence of these glands and their structure correlate with recent molecular phylogenies.
