The Epidendroideae are a group of mostly epiphytic orchids in which roots bear a multi-layered, spongy epidermis (the velamen), and floral abscission often occurs (Freudenstein & Rasmussen 1999). A subgroup of forms with the pollinium bearing a tegula, a strap formed from the epidermis of the rostellum, has sometimes been recognised as a distinct subfamily Vandoideae but may not be monophyletic.
