Aeridinae

Aeridinae
In the botanical classification of plants, Aeridinae Pfitzer (formerly Sarcanthinae) is a subtribe of the tribe Vandeae (Family Orchidaceae) whose representatives all have a monopodial growth habit and do not possess pseudobulbs.
This subtribe is a monophyletic group within Vandeae, and it contains more than 1,300 species in 103 genera, including about 208 (38%) hybrid genera. They occur mostly in Asia with a few in Africa. They are distinguished from the other subtribes of Vandeae by having an entire rostellum, a relatively small spur formed by the lip, and four (or two) pollinia.
Some of the genera it contains have some of the largest and most spectacular flowers in the whole of the orchid family. Also included in this subtribe are some of the most economically important genera in the horticultural trade, such as Phalaenopsis and Vanda.
Leaflessness
Aeridinae contains the largest diversity of leafless taxa within the tribe Vandeae. These leafless species of the genera Chiloschista, Phalaenopsis, and Taeniophyllum (syn. Microtatorchis), which is the most species rich genus of Aeridinae with 245 accepted species, exhibit reduced stems and enhanced importance and photosynthetic function of the root system. This extreme reduction of leaves has likely evolved in three to four separate instances within Aeridinae. These leafless genera have a tight relationship with fungi of the Ceratobasidiaceae family. The roots of leafless epiphytic orchids are also heavily colonized by nitrogen-fixating cyanobacteria, which are thought to supply the plants with nitrogen.
Phylogeny
The subtribe Aeridinae is the sister group to the subtribe Angraecinae (incl. Aerangidinae):
