(200), Dendrochilum Blume (278), Dickasonia L.O.Williams (1), Dilochia Lindl. & Olszewski (2). It could be argued that it would be better to split a large genus such as Epidendrum into many smaller, more morphologically homogeneous genera, but the authors of the treatment in Pridgeon et al. (14), Pygmaeorchis Brade (2), Quisqueya Dod (4), Rhyncholaelia Schltr. Agrostophyllinae in Chase et al. (33), Chysis†Lindl. Calypso and its relatives have long been considered as an independent tribe but, in Górniak et al. is sister to Cyanicula (Jones et al., 2001). Relationships of the subtribes are not entirely resolved/supported (Fig. (2), Prescottia Lindl. (165), Epidendrum L. (1413), Guarianthe Dressler & W.E.Higgins (4), Hagsatera R.González (2), Homalopetalum Rolfe (8), Isabelia Barb.Rodr. The next step was taken in 1830-1840 by John Lindley, who recognized four subfamilies. (2005). ex Jenny (1), Stanhopea J.Frost ex Hook. 1. (2005), it was tentatively placed in Neottieae. & Westc. (2014), this is made clearer. This classification, published in 1981 in the book The Orchids: Natural History and Classification, was widely accepted by botanists and growers before the publication of Genera Orchidacearum. 2003) established Sirindhornia for two unusual new species from northern Thailand. (2003), we include Aulostylis Schltr. Nucleotide. There is also evidence that distinctive genera, such as Dendrochilum and Pholidota, are not monophyletic, and so even treating these as subgenera or sections of Coelogyne s.l. 1999. (2005) and Wu, Raven & Hong (2009). Chysis, however, falls with moderate support as sister to Bletiinae and, as none of the other studies strongly refutes this placement, we treat it as a member of Bletiinae, which is otherwise unchanged. An exclusive relationship of Hederorkis to Polystachya has not been demonstrated (Pridgeon et al., 2014), but it also has not been strongly refuted. (21), Microsaccus Blume (12), Mobilabium Rupp (1), Omoea Blume (2), Ophioglossella* Schuit. & Baranow, as proposed by Mytnik-Ejsmont (2011) and coworkers. (Schuiteman & de Vogel, 2003; Pridgeon et al., 2005). Calochilus R.Br. Solano, Salazar & Jiménez (2011) merged Microthelys Garay with Funkiella; the species assigned to these genera are mingled in the molecular phylogenetic trees (Salazar, 2003a). (5), Peristeria Hook. (3), Thelyschista Garay (1), Veyretia Szlach. Aglossorrhyncha† Schltr. These five subfamilies were all strongly supported as monophyletic groups in subsequent studies. (2), Leptoceras (R.Br.) (45), Pilophyllum† Schltr. A prominent example in which such splitting of a genus was eventually accepted is that of Cypripedium, which had been the sole genus of that subfamily (or even family). Aracamunia Carnevali & I.Ramírez (1), Aulosepalum Garay (7), Beloglottis Schltr. (2012) who analysed plastid DNA. (Jones et al., 2001), for which no type was cited. 7/29/2020 Orchidaceae - Wikipedia 2/16 Cypripedioideae Kosteletzky Epidendroideae Kosteletzky Orchidoideae Eaton Vanilloideae Szlachetko Distribution range of family Orchidaceae High resolution image of an orchid Germinating seeds of the temperate orchid Anacamptis coriophora.The protocorm is the first organ that will develop into true roots and leaves. The floral features of mycoheterotrophic Risleya appear to be similar to those of Malaxis, but it has pollinia with a viscidium and an elongate rostellum, both of which fit better in Collabieae. Direct links. Lindl. Plants with mealy or paste-like pollen, which ordinarily are not aggregated into pellets, called pollinia, with two or three fertile long anthers, leaves with sheathing bases, elongated staminode and labellum similar to the petals. All studies conducted thus far indicate that it is paraphyletic to several genera, including Bonatea, Gennaria and Pecteilis (Ponsie et al., 2007; Bateman et al., 2009; Inda, Pimentel & Chase, 2012; Batista et al., 2013). Harvard University Press ISBN 0-674-87525-7-- It is the best popular scientific account of the orchids, their biology, evolution, and classification. In terms of specific problematic groups, as noted earlier, a major challenge is to resolve relationships among Old World Habenaria, which implies sampling broadly among representatives of as many as possible of the roughly 25 genera of the former ‘Habenariinae’ (Orchidinae group 2 sensu Pridgeon et al., 2003), as the molecular phylogenetic analyses of Batista et al. (267), Cyanicula Hopper & A.P.Brown (10), Elythranthera (Endl.) (1), Listrostachys Rchb.f. Catasetum Rich. (17), Mycaranthes* Blume (36), Notheria* P.O'Bryne and J.J.Verm. data). In a more thoroughly sampled study, Cameron & van den Berg (in press) found that, with 18S rDNA and two mitochondrial DNA regions, the position of Pogoniopsis was more likely to be in accord with its morphology, and we thus place it near Triphora here. & Szlach. (2001a). (2009) included it in Ponerorchis in the treatment for the Flora of China. A great deal more study is needed before adjusting the generic limits in this group. Aplectrum Nutt. (2010a, b). Other newly described genera are merely the result of splitting of genera demonstrated to be monophyletic, such as Masdevallia, Dendrobium and Corybas; the benefits of splitting are unclear to us, and we have resisted this sort of taxonomic change. (5), Oeoniella Schltr. (2), Systeloglossum Schltr. Likewise, in Nervilieae, we recognize Nervilia to be in a separate subtribe from the rest. (2), Aporostylis Rupp & Hatch (1), Caladenia R.Br. (15). (2), Jumellea Schltr. Many of the species develop pseudobulbs (i.e. (56), Notyliopsis P.Ortiz (2), Oliveriana Rchb.f. Thirty-five tribes are used in Asteraceae versus 21 in Orchidaceae. (2010), this relationship was well supported. (69), Tetramicra Lindl. (136), Platycoryne Rchb.f. (2009) should be consulted for more information. Ceratandra Lindl. (1), Podangis Schltr. Some are related to genera that are polyphyletic, such as Habenaria and Eulophia, and accepting additional genera in such groups is premature until a well-sampled phylogenetic study has been completed. ], we argue for a more considered and well-sampled analysis prior to making taxonomic decisions about generic delimitation. Thus, we keep Hederorkis in Polystachyinae here, but this relationship should be the focus of additional study. Some even say the number of species is above 35000. In Cranichidinae, several studies (Figueroa et al., 2008; Álvarez-Molina & Cameron, 2009; Salazar et al., 2009) have shown that a pair of species, Prescottia tubulosa (Lindl.) It is now known to occur in Papua New Guinea as well. (9), Kegeliella Mansf. (1), Domingoa Schltr. (13), Brachycorythis Lindl. In the relative scheme of what was known about orchids in 1993 (Dressler, 1993), the past 20 years have seen the resolution of many major questions. ); Adanson, Fam. f. – bletilla P : Contains 1 Species and 1 accepted taxa overall : Down one level : Species Bletilla striata (Thunb.) (7), Brassia R.Br. (2). D.L.Jones & M.A.Clem., which had been considered to be a member of Caladenia, but which falls outside that genus as sister to either Glossodia/Elythranthera with nrITS DNA sequences (Jones et al., 2001) or Caladenia/Cyanicula with plastid matK DNA sequences. Burnettia Lindl. Another of the unplaced subtribes in Chase et al. (25), Amesiella Schltr. There are exceptions to this general pattern, such as Devogelia (Schuiteman, 2004) and Danxiaorchis (Zhai et al., 2013), the former not obviously morphologically similar to any other genus of Epidendroideae and the latter a member of Calypsoinae, as documented by molecular studies. Mark W. Chase, Kenneth M.Cameron, Russell L. Barrett, John V. Freudenstein DNA data and Orchidaceae Systematics : A new Phylogenetic Classification by [7] It covers all of the known orchids, including a description of each genus. Although Jones et al. Martos et al. (5). (3), Nephelaphyllum Blume (11), Pachystoma Blume (3), Phaius Lour. (14), Diaphananthe Schltr. Auxopus Schltr. Sixty-eight apomorphies grouped into forty-two transformation series were used to construct a cladogram for the twenty-six tribes of the family. This classification was first presented in a paper that Bentham read to the Royal Society in 1881. (835), Hemipilia Lindl. In Freudenstein & Chase (2015) (an analysis of eight DNA regions focusing on Epidendroideae), Coelia falls as sister to Calypsoeae with high bootstrap support in both maximum likelihood and parsimony analyses, and we include it there. (7), Pyrorchis D.L.Jones & M.A.Clements (2), Rimacola Rupp (1), Waireia D.L.Jones, Molloy & M.A.Clements (1). (2003). "DNA data and Orchidaceae systematics: a new phylogenetic classification". Differences in morphology between these species are minor. & Averyanova is undoubtedly closely related and probably synonymous. Luisia includes the recently described Lockia Aver. (2007, on Bonatea), but their sampling was narrowly focused and therefore did not allow for a truly stringent assessment of generic monophyly. 1753. [7] In 2015, Chase et alii merged even more genera, reducing their number to 736. (1), Chondrorhyncha Lindl. Finally, Calanthe subgenus Preptanthe is sister to the rest of this clade. Four major clades within the remainder of Epidendroideae are recognized: Vandeae/Podochileae/Collabieae, Cymbidieae, Malaxideae and Epidendreae, the last now including Calypsoinae (previously recognized as a tribe on its own) and Agrostophyllinae s.s. Agrostophyllinae and Collabiinae were unplaced subtribes in the 2003 classification. (15), Caleana R.Br. The Orchidaceae, commonly referred to as the orchid family, is a morphologically diverse and widespread family of monocots in the order Asparagales.Along with the Asteraceae, it is one of the two largest families of flowering plants, with between 21,950 and 26,049 currently accepted species, found in 880 genera.
