Tsaiorchis keiskeoides is a species of flowering plant in the family Orchidaceae, native to northern Vietnam. [1]
The species was first described in 1931 by François Gagnepain, as Habenaria keiskeoides. It was transferred to the genus Amitostigma in 1985. [1] A molecular phylogenetic study in 2014 treated Habenaria keiskoides as synonymous with Tsaiorchis neottianthoides . Although Tsaiorchis was shown to be close to some other genera, including Ponerorchis when expanded to include Amitostigma, it was regarded as sufficiently distinct to be maintained as a separate genus. [2] Sources such as the World Checklist of Selected Plant Families treat Tsaiorchis keiskeoides as a distinct species from Tsaiorchis neottianthoides. [1]

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.
Ponerorchis cucullata, formerly Neottianthe cucullata, is a species of flowering plant in the family Orchidaceae, native to temperate Eurasia from Poland to Japan, and also to the Himalayas. It is terrestrial, growing from tubers, to a height of up to 30 cm, with pinkish flowers arranged in a one-sided spike. It was placed in several different genera before a study in 2014 showed that it belonged in an expanded Ponerorchis.
