Tsaiorchis is a genus of flowering plants in the family Orchidaceae.
Tsaiorchis is placed in the orchid subfamily Orchidoideae, tribe Orchideae, subtribe Orchidineae. The relationship between Tsaiorchis and the rest of the subtribe is as shown in the cladogram below. [2]

Although Tsaiorchis was shown to be sister to an expanded genus Hemipilia , the two have significant differences. Hemipilia grows from tubers, Tsaiorchis has horizontally extending rhizomes. The detailed structure of the flowers is also different. [2]
Tsaiorchis contains the following species: [3]
Ponerorchis yueana is a species of plant in the family Orchidaceae. It is endemic to China, known only from Sichuan and Yunnan. It produces pink or white flowers. The epithet is also spelt "yuana".
Orchideae is a tribe of orchids in the subfamily Orchidoideae. Historically, it was divided into 2 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.
Galearis camtschatica is a species of flowering plants in the orchid family, Orchidaceae, native to Korea, northern Japan, and the Russian Far East.
Gennaria griffithii is a species of flowering plant in the family Orchidaceae, native from Afghanistan to China. It is a terrestrial species, with a small tuber and small greenish flowers, found in damp places. It has a complicated taxonomic history, having been transferred between genera several times. When placed in a genus on its own it is correctly known as Dithrix griffithii. In 2015, it was transferred to the genus Gennaria.
