Diseae

Diseae is an orchid tribe in the subfamily Orchidoideae. It was recognized in Genera Orchidacearum volume 2, which was published in 2001. It consisted of 12 genera in five subtribes. In molecular phylogenetic studies that were published after 1999, it was shown that Diseae is paraphyletic over the tribe Orchideae. In a classification of orchids that was published in 2015, Diseae was not recognized, but was instead placed in synonymy under Orchideae. In 2007, a molecular phylogenetic study showed that the large genus Disa (~182 species) is paraphyletic over the small genus Schizodium. Accordingly, in the 2015 classification, the genus Schizodium was sunk into Disa. Also, the subtribe Huttonaeinae was sunk into Disinae, and the subtribe Satyriinae was sunk into Orchidinae. The expanded tribe Orchideae consisted of the subtribes Brownleeinae, Disinae, Coryciinae, and Orchidinae. Disperis was transferred from Coryciinae to Brownleeinae and Pachites was transferred from Satyriinae to Disina......read more on Wikipedia.
