In a classification of orchids that was published in 2015, the genera Brownleea and Disperis constituted the subtribe Brownleeinae of the tribe Orchideae.[2] A sister relationship between Brownleea and Disperis received only weak statistical support in a 2009 study.[3] In Genera Orchidacearum, the subtribe Brownleeinae was placed in the tribe Diseae,[4] but this tribe is no longer recognized because it has been shown to be paraphyletic over the tribe Orchideae.
