Disinae
Disinae is a subtribe of orchids that has been differently defined and placed in the two classification systems that are currently in use for orchids. ''Genera Orchidacearum'', which is currently the definitive work on orchid taxonomy, delimits Disinae as consisting of two closely related genera, ''Disa'' and ''Schizodium'', and it places Disinae in the mostly African tribe Diseae, along with four other subtribes: Brownleeinae, Huttonaeinae, Coryciinae, and Satyriinae.〔Alec M. Pridgeon, Phillip J. Cribb, Mark W. Chase, and Finn N. Rasmussen. 1999-2014. ''Genera Orchidacearum'' Oxford University Press. ISBN 978-0-19-850513-6 (volume 1), ISBN 978-0-19-850710-9 (volume 2), ISBN 978-0-19-850711-6 (volume 3), ISBN 978-0-19-850712-3 (volume 4), ISBN 978-0-19-850713-0 (volume 5), ISBN 978-0-19-964651-7 (volume 6)〕 In the classification for orchids that was published by Chase et alii in 2015, ''Schizodium'' was placed in synonymy under ''Disa'', while ''Pachites'' and ''Huttonaea'' were transferred to Disinae.〔Mark W. Chase, Kenneth M. Cameron, John V. Freudenstein, Alec M. Pridgeon, Gerardo A. Salazar, Cássio van den Berg, and André Schuiteman. 2015. "An updated classification of Orchidaceae". ''Botanical Journal of the Linnean Society'' 177(2):151-174. (See ''External links'' below).〕 In ''Genera Orchidacearum'', ''Pachites'' and ''Satyrium'' form the subtribe Satyriinae, and ''Huttonaea'' is the sole genus in the subtribe Huttonaeinae. The transfer of ''Pachites'' and ''Huttonaea'' to Disinae by Chase et alii (2015) was done with considerable doubt, and was based upon uncertainty about the relationships of these two genera. In 2009, a molecular phylogenetic study found only weak statistical support for a sister relationship between ''Huttonaea'' and ''Disa''.〔Richard J. Waterman, Anton Pauw, Timothy G. Barraclough, and Vincent Savolainen. 2009. "Pollinators underestimated: A molecular phylogeny reveals widespread floral convergence in oil-secreting orchids (sub-tribe Coryciinae) of the Cape of South Africa". ''Molecular Phylogenetics and Evolution'' 51(1):100-110. .〕
Disinae was covered, along with the rest of the tribe Diseae, in volume 2 of ''Genera Orchidacearum'', which was published in 2001. Molecular phylogenetic studies published after 2001 showed that Diseae was paraphyletic over another tribe, Orchideae. Consequently, Chase et alii (2015) combined Diseae and Orchideae into a larger version of Orchideae and included Disinae as one of its subtribes.
The subtribe Disinae was erected by George Bentham in 1881,〔Disinae in International Plant Names Index. (see ''External links'' below).〕〔George Bentham. 1881. page 288. In: "Notes on Orchideae". ''The Journal of the Linnean Society. Botany''. 18(110):281-367. (See ''External links'' below).〕 in preparation for the publication of a new classification of orchids in the 1883 edition of ''Genera Plantarum'' (Bentham & Hooker).〔George Bentham and Joseph Dalton Hooker. 1883. ''Genera Plantarum'' (Bentham & Hooker) volume 3, part 2, pages 460-488. L.Reeve & Co.; Williams & Norgate: London, UK. (See ''External links'' below).〕 Using the suffixes of that time for taxonomic rank, he called it subtribe "Diseae" of his now obsolete tribe Ophrydeae.
