Coryciinae 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 Coryciinae as consisting of five genera: ''Disperis'', ''Evotella'', ''Ceratandra'', ''Pterygodium'', and ''Corycium'', and it places Coryciinae in the mostly African tribe Diseae, along with four other subtribes: Brownleeinae, Huttonaeinae, Disinae, 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)〕 The genera of Coryciinae are small to medium in size and the number of species in each genus is as follows: ''Disperis'' (78), ''Pterygodium'' (19), ''Corycium'' (15), ''Ceratandra'' (6), and ''Evotella'' (1).〔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).〕 Coryciinae 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 ''Disperis'' is most closely related to ''Brownleea'', rather than to the other genera of Coryciinae. They also showed that the tribe Diseae is paraphyletic over the tribe Orchideae.〔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. .〕 The smaller version of Coryciinae, with ''Disperis'' excluded, is known as Coryciinae sensu stricto, and has 41 species. In the classification for orchids that was published by Chase et alii in 2015, ''Disperis'' was transferred to the subtribe Brownleeinae and the tribe Orchideae was expanded to include the former Diseae, with Coryciinae as one of its subtribes.〔 Coryciinae orchids secrete oil from a lip appendage on their flowers, and pollination occurs when female Rediviva bees (Melittidae) collect the oil, probably for use as a larval provision (Pauw 2006; fig. 1A). As with other orchids, pollen is placed onto precise locations on the body of the pollinator in packages called pollinaria (Pauw 2006; fig. 1B). The oil-secreting lineages of Coryciinae are largely endemic to South Africa, with two centers of diversity: a summer-rainfall area centered in the Drakensberg range and a winter-rainfall area in the Western Cape province and Namaqualand (Linder and Kurzweil 1999). == See also == * Taxonomy of the Orchidaceae 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Coryciinae」の詳細全文を読む スポンサード リンク
