This tribe contains 1,700 - 2,000 species in more than 150 genera.[3]
Epiphytic
These orchids are pantropical
epiphytes and occur in tropical Asia, the Pacific Islands, Australia and Africa. Many of these orchids are
horticulturally important, especially Vanda and Phalaenopsis.
Subtribe
Aeridinae (formerly, illegitimate subtribal name Sarcanthinae): largest subtribe with more than 1,000 species in 103 genera, including about 200 hybrid species; occurs mostly in Asia and Australia and with a few in Africa. They are distinguished from the other subtribes by having an entire
rostellum, a relatively small
spur formed by the lip, and four (or two)
pollinia.
Subtribe
Angraecinae Summerh.: about 400 species in 19 genera. They occur in tropical Africa, Madagascar, the Mascarene and Comoros Islands and two genera in tropical America. They are distinguished from the other subtribes by having an apron-like rostellum, an elongate spur, and two pollinia.
Subtribe
Polystachyinae (formerly part of the Epidendreae) : about 220 species in two genera : Hederorkis and Polystachya. They all show four pollinia. The lip often has mealy hairs called pseudopollen on the upper surface.
The following phylogenetic tree shows the relationships among the subtribes:[5]
Vandeae s.l.
Aeridinae
Angraecinae (including Aerangidinae)
Adrorhizinae
Polystachyinae
The subtribe
Aerangidinae Summerh. is increasingly included within Angraecinae. The subtribe Angraecinae is a well supported, monophyletic group under the inclusion of Aerangidinae. Separating these groups would make them polyphyletic.[6][7]
The divergence time of Vandeae has been estimated to be 25.31 Mya.[1]
