'''''Epidendroideae''''' is the largest subfamily of ''Orchidaceae'', with three quarters of all known [[species]], split into several [[tribe]]s and subtribes, encompassing more than five hundred [[genera]] and about twenty thousand species distributed almost all over the world, except in the dryer deserts and polar areas; known for being orchids with coherent [[pollen]] forming pollinia and with one incumbent [[anther]] only, or with the anther bent back, but then with clearly plicate leaves and roots hardly ever fleshy.

Epidendroideae is the largest subfamily of Orchidaceae, with three quarters of all known species, split into several tribes and subtribes, encompassing more than five hundred genera and about twenty thousand species distributed almost all over the world, except in the dryer deserts and polar areas. They are known for being orchids with coherent pollen forming pollinia and with one incumbent anther only, or with the anther bent back, but then with clearly plicate leaves and roots hardly ever fleshy.

Except for Vanilla species which belong to subfamily Vanilloideae, the species of Cypripedioideae and a few others cultivated by specialists and by botanic gardens, almost the totality of cultivated orchids belong to Epidendroideae.

Epidendroideae is divided in two groups of tribes, one is more primitive (the basal Epidendroideae) and subordinates the genera which diverged in early degrees of its evolution, still sharing some characteristics with Orchidoideae; the other group (High Epidendroideae) has very few in common with the said subfamily. The relationships amongst all tribes are not well established thus these cladograms are only provisional:
