}}Ponerorchis tetraloba (synonym Amitostigma tetralobum) is a species of plant in the family Orchidaceae. It is endemic to China known from only Sichuan and Yunnan.[1][2][3] The flowers are pink or pale purple.[2] TaxonomyThe species was first described in 1912 by Achille Eugène Finet, as Peristylus tetralobus. It has been placed in both Orchis and Amitostigma.[1] 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.
