Ponerorchis parceflora is a species of flowering plant in the family Orchidaceae, native to south-central China (north-east Sichuan, Chongqing). The epithet has been mis-spelt "parciflora" by some authors.
Taxonomy.
The species was first described in 1902 by Achille Eugène Finet, as "Peristylus tetralobus" f. "parceflorus". It was later raised to a full species and transferred to the genus "Amitostigma" as "Amitostigma parceflorum". 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 parceflora".
