Orchidoideae Eaton (1836)
The Orchidoideae, or the orchidoid orchids, are a subfamily of the orchid family (Orchidaceae).
They typically contain the orchids with a single (monandrous), fertile anther which is erect and basitonic.
The subfamily Orchidoideae and the previously recognized subfamily Spiranthoideae are considered the closest allies in the natural group of the monandrous orchids because of
* a shared terrestrial habit
The Orchidoideae contain two subclades with the following tribes :
* tribes Orchideae and Diseae
The former subfamily Spiranthoideae is now embedded as tribe Cranichideae in the clade of the Orchidoideae. It is sister to the tribe Diurideae.
The tribe Orchideae consists of the following subtribes:
The tribe Diseae consists of the following subtribes:
The monophyletic tribe Cranichideae consists of the following monophyletic subtribes :
The tribe Diurideae consists of the following subtribes :
* Acianthinae (monophyleric)
