Taxonomy edit
The species was first described in 1912 by Achille Eugène Finet, as Peristylus tetralobus. It has been placed in both Orchis and Amitostigma.[2] A molecular phylogenetic study in 2014, in which this species was included as Amitostigma tetralobum, 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 tetraloba.[4]
