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.
