Ponerorchis dolichocentra
Ponerorchis dolichocentra is a species of flowering plant in the family Orchidaceae, native to south-central China (west Sichuan). Taxonomy. The species was first described in 1982 as "Amitostigma dolichocentrum". 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 "Amitostigma dolichocentrum" becoming "Ponerorchis dolichocentra".
