5-410: Cranichideae is an orchid tribe in the subfamily Orchidoideae . This Orchidoideae -related article is a stub . You can help Misplaced Pages by expanding it . Orchidoideae See text The Orchidoideae , or the orchidoid orchids, are a subfamily of the orchid family ( Orchidaceae ) that contains around 3630 species. Species typically have a single ( monandrous ), fertile anther which
10-550: Is erect and basitonic . The subfamily Orchidoideae and the previously recognized subfamily Spiranthoideae are considered the closest allies in the natural group of the monandrous orchids because of several generally shared characters: Phylogeny of the Orchidoideae is volatile and still subject to change. Historically, the Orchidoideae have been partitioned into up to 6 tribes , including Orchideae , Diseae , Cranichideae , Chloraeeae , Diurideae , and Codonorchideae . However,
15-638: The Orchidinae and Habenariinae (a nonsystematic paraphyletic splitting), the Orchideae now comprise 6 subtribes. Along with previous molecular studies, Chase et al's 2015 analysis confirmed that Diseae was a polyphyletic grouping. Consequently, the former subtribes of Diseae have been redistributed within the Orchideae (for instance, Satyrium is now classified in the Orchidinae). In his 2015 study Chase recommended further study of historically problematic genera in
20-692: The former Chloraeeae are sister to the rest of the Cranichideae. As such, the Chloraeeae are now considered a subtribe of the Cranichideae. Moreover, based on morphological and genetic evidence, the genus Discyphus was elevated out of the Spiranthinae to form its own monophyletic subtribe, the Discyphinae . Chloraeinae Pterostylidinae Goodyerinae Galeottiellinae Manniellinae Spiranthinae Discyphinae Cranichidinae Once divided into
25-498: The most recent molecular phylogenetics analysis led by Chase et al. in 2015 and subsequently by Chen et al. in 2017 indicates that the Orchidoideae should be split into 4 tribes: the Orchideae, Cranichideae, Diurideae, and Codonorchideae. This monophyletic tribe consists of only one genus, Codonorchis , found in South America . This cosmopolitan tribe comprises 8 currently accepted subtribes. Molecular evidence suggests that
