Distribution of Apostasioideae

Apostasioideae is one of the five subfamilies recognised within the orchid family,

genera, Neuwiedia and Apostasia, and 15 species
, are recognised within the Apostasioideae in contrast to the other orchid subfamilies which are highly species rich.

The Apostasioideae are generally considered a basal lineage within the orchids

monandrous (possessing a single stamen
), however Apostasioid orchids have 3 stamens.

As with all basal or 'primitive' groups,

extant species within Apostasioideae do not represent direct ancestors of the other subfamilies, they simply share the same common ancestor. However, by having followed a separate evolutionary pathway from the other orchids extant Apostasioid orchids may allow biologists to make inferences about features present in that common ancestor.[3]
