Orchideae is a tribe of orchids in the subfamily Orchidoideae. It has been divided into two subtribes, Orchidinae and Habenariinae. The subtribe Orchidinae alone contains about 1,800 species. However, although some phylogenetic studies have established the monophyly of the subtribes, the generic boundaries are unclear, with many genera as traditionally circumscribed being paraphyletic or even polyphyletic. Species of genera such as Habenaria and Platanthera have been placed into both subtribes. A 2017 molecular phylogenetic study found that both subtribes did form clades, but did not formally recognize Habenariinae, because of missing genera and uncertainty over generic boundaries. The Asian species of Orchideae, in particular, have been subject to repeated changes of generic placement from 2012 onwards.
