Taxonomy

As of March 2014, there are discrepancies in the spelling of the specific epithet. The World Checklist of Selected Plant Families and the International Plant Names Index spell it "yueanum", noting that the original description used the form "yüanum".[2][4] The Flora of China and the authors who moved it to the genus Ponerorchis spell it "yuanum".[3][5] Other sources are divided between these two spellings.

The species was first described in 1912 by Tsin Tang and Fa Tsuan Wang, as Amitostigma yueanum.[4] A molecular phylogenetic study in 2014, in which this species was included, found that species of Amitostigma, Neottianthe and Ponerorchis were mixed together in a single clade, making none of the three genera monophyletic as then circumscribed. Amitostigma and Neottianthe were subsumed into Ponerorchis, with this species becoming Ponerorchis yueana.[5]

gollark: Stay here, it would be inconvenient and expensive not to.
gollark: The application system here is actually very weird - you don't get grades until August, 2 months before university terms start, but you do applications in September (the **previous** September) to January.
gollark: Not for universities.
gollark: Possibly.
gollark: Probably going to university to do something or other in 2 years, and "something" might be engineering of some sort, but I don't technically have to decide on that for *one* year so procrastination time.
