Ponerorchis amplexifolia

Ponerorchis amplexifolia is a species of flowering plant in the family Orchidaceae, native to south-central China (west Sichuan).
Taxonomy.
The species was first described in 1936 by Tsin Tang and Fa Tsuan Wang as "Amitostigma amplexifolium". A molecular phylogenetic study in 2014 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 amplexifolia".
