In molecular phylogenetic studies that were published after 1999, it was shown that Diseae is paraphyletic over the tribe Orchideae.

[2] In a classification of orchids that was published in 2015, Diseae was not recognized, but was instead placed in synonymy under Orchideae.

The expanded tribe Orchideae consisted of the subtribes Brownleeinae, Disinae, Coryciinae, and Orchidinae.

Diseae accounts for more than half of the orchids of southern Africa and has about 400 species.

[6] Disperis has a few species in tropical Africa and Asia, including Malesia.
