Papilionanthe vandarum

The sub-tribe Aeridinae is part of the family Orchidaceae,the sub-family Epidendroideae, tribe Vandeae.

The representatives are all monopodal and have no pseudobulbs.

This sub-tribe contains more than 1,300 species divided into 103 genera, of which approximately 40% of hybrid lineages.

They are found mainly in Asia and a few occur in Africa.

They are distinguished from the other sub-tribes of Vandeae by owning a rostellum, a relatively small spur formed by the lip, and four (or two) pollinia.

Part of the families of Aeridinae possess some of the largest and most spectacular flowers of all the Orchidaceae family.

Also included in this sub-tribe are some of the most economically important genera in horticulture, such as Phalaenopsis and Vanda.
