Ponerorchis kinoshitae

Ponerorchis kinoshitae is a species of flowering plant in the family Orchidaceae, native to the south Kuril Islands and northern Japan (Hokkaido, north Honshu).
Taxonomy.
The species was first described in 1903 by Tomitaro Makino as "Gymnadenia keiskei" var. "kinoshitae". In 1909, he raised it to a full species as "Gymnadenia kinoshitae". It was later transferred to other genera, including "Orchis" and "Amitostigma". 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 kinoshitae".
