Arethuseae is a mid-sized tribe of orchids in the subfamily Epidendroideae. This tribe was initially categorized by John Lindley in 1840. Its largest subtribes are Arethusinae and Coelogyninae.
Bletiinae was once considered a subtribe of Arethuseae, but it was moved to Epidendreae in 2005.Sobraliinae has been considered a subtribe of Arethuseae, but is now recognized at the rank of tribe within the subfamily Epidendroideae. The genus Thunia has been considered to be the only genus in the subtribe Thuniinae, but is now included in the subtribe Coelogyninae.
The taxonomy of the Orchidaceae has evolved slowly during the last 250 years, starting with Carl Linnaeus who in 1753 recognized eight genera. De Jussieu recognized the Orchidaceae as a separate family in his Genera Plantarum in 1789. Olof Swartz recognized 25 genera in 1800. Louis Claude Richard provided us in 1817 with the descriptive terminology of the orchids.. The next step was taken in 1830-1840 by John Lindley, who recognized four subfamilies. He is generally recognized as the father of orchid taxonomy. The next important step was taken by George Bentham with a new classification, recognizing subtribes for the first time. This classification was first presented in a paper that Bentham read to the Royal Society in 1881. Then it was published in 1883 in the final volume of Genera Plantarum. The next great contributors were Pfitzer (1887), Schlechter (1926), Mansfeld (1937), Dressler and Dodson (1960), Garay, Vermeulen (1966), again Dressler (1981). and Burns-Balogh and Funk (1986). Dressler's 1993 book had considerable influence on later work.
Vanilloideae is one of the subfamilies of orchids belonging to the large family Orchidaceae.
Coelia is a genus of orchids. It contains 5 species, native to Mexico, Central America and the West Indies.
Thunia is a genus of orchids. It is now included in the subtribe Coelogyninae, but was previously treated as the only genus of the subtribe Thuniinae. The genus comprises 6 species, native to Southeast Asia. It is abbreviated Thu in trade journals.
Laeliinae is a Neotropical subtribe including 40 orchid genera, such as Brassavola, Laelia and Cattleya. The genus Epidendrum is the largest within this subtribe, containing about 1500 species. This is followed by the genus Encyclia, with over 120 species.
Pogoniopsis is a genus of orchids. It contains two known species, both endemic to Brazil. It was previously included in the subfamily Vanilloideae, but is now placed in the tribe Triphoreae of the subfamily Epidendroideae.
Bletiinae is a small-sized subtribe of orchids in the tribe Epidendreae of the subfamily Epidendroideae.
Ponerinae is a subtribe of the Orchidaceae tribe Epidendreae. The Ponerinae are characterized by sympodial stems that do not form pseudobulbs, bear two or more leaves, and a racemose or paniculate inflorescence carrying flowers with four or six pollinia.
The tribe Epidendreae of the Orchidaceae comprises six subtribes:
Vargasiella is a genus of flowering plants from the orchid family, Orchidaceae. It contains two species, both endemic to South America: It has been treated as the only genus in the subtribe Vargasiellinae, but more recently has been included in the subtribe Zygopetalinae.
Risleya is a monotypic genus of flowering plants from the orchid family, Orchidaceae. The sole species is Risleya atropurpurea. It is native to the Himalayas of Sichuan, Tibet, Yunnan, Bhutan, India, Sikkim, Assam and Myanmar. It was previously included in the subtribe Malaxidinae but is now placed in the tribe Collabieae.
Silvorchis is a genus of flowering plants from the orchid family, Orchidaceae. Only one species is known, Silvorchis colorata, endemic to Java. This is a holomycotrophic species, completely lacking in chlorophyll.
The Eriinae form a subtribe of Podochileae, a tribe of the orchid family (Orchidaceae). The name is derived from the genus Eria.
Dendrobieae is a tribe in the subfamily Epidendroideae, in the family Orchidaceae.
The Coelogyninae are an orchid subtribe in the tribe Arethuseae.
Gastrodieae is an orchid tribe in the subfamily Epidendroideae.
Malaxideae is an orchid tribe in the subfamily Epidendroideae.
Malaxidinae is an subtribe of orchids in the tribe Malaxideae of the subfamily Epidendroideae.
Neottieae is an orchid tribe in the subfamily Epidendroideae.
Arethusinae is an orchid subtribe in the tribe Arethuseae.
