Species

Thunia is a genus of orchids (family Orchidaceae). It is now included in the subtribe Coelogyninae, [1] 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.

Aeridinae

In the botanical classification of plants, Aeridinae is a subtribe of the Tribe Vandeae whose representatives all have a monopodial growth habit and do not possess pseudobulbs.

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.

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.

Galeottiella is a genus of flowering plants from the orchid family, Orchidaceae. Traditionally it had been included in subtribe Spiranthinae, but following molecular phylogenetic and morphological studies it is now placed in a subtribe on its own, Galeottiellinae.

Dendrobieae Tribe of orchids

Dendrobieae is a tribe in the subfamily Epidendroideae, in the family Orchidaceae.

Orchideae

Orchideae is a tribe of orchids in the subfamily Orchidoideae. It has been divided into two subtribes, Orchidinae and Habenariinae. The subtribe Orchidinae alone contains about 1,800 species. However, although some phylogenetic studies have established the monophyly of the subtribes, the generic boundaries are unclear, with many genera as traditionally circumscribed being paraphyletic or even polyphyletic. Species of genera such as Habenaria and Platanthera have been placed into both subtribes. A 2017 molecular phylogenetic study found that both subtribes did form clades, but did not formally recognize Habenariinae, because of missing genera and uncertainty over generic boundaries. The Asian species of Orchideae, in particular, have been subject to repeated changes of generic placement from 2012 onwards.

Diseae

Diseae is an orchid tribe in the subfamily Orchidoideae. It was recognized in Genera Orchidacearum volume 2, which was published in 2001. It consisted of 12 genera in five subtribes. In molecular phylogenetic studies that were published after 1999, it was shown that Diseae is paraphyletic over the tribe Orchideae. In a classification of orchids that was published in 2015, Diseae was not recognized, but was instead placed in synonymy under Orchideae.

Spiranthinae

Spiranthinae is an orchid subtribe in the tribe Cranichideae.

Eulophiinae

Eulophiinae is an orchid subtribe in the tribe Cymbidieae. It comprises 270 species divided into nine genera, with the genus Eulophia comprising 60% of these species.

Maxillariinae

Maxillariinae is an orchid subtribe in the tribe Cymbidieae. It was formerly treated as the tribe Maxillarieae, and divided into a number of subtribes.

Epipogiinae is an orchid subtribe in the tribe Nervilieae.

Disinae A subtribe of flowering plants belonging to the orchid family

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. 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. 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.
