Ponerorchis farreri

Ponerorchis farreri is a species of flowering plant in the family Orchidaceae, native from south-east Tibet to south-central China (north-west Yunnan).
Taxonomy.
The species was first described in 1924 by Rudolf Schlechter, as "Amitostigma farreri". 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 farreri" becoming "Ponerorchis farreri".
