Ponerorchis secundiflora (synonym Neottianthe secundiflora) is a species of plant in the family Orchidaceae. It is native from the Himalayas to China.[1]


The species was described by Joseph Dalton Hooker in 1890, under the name "Habenaria secundiflora".[1] However, this name had already been used for a different species in 1881, so was illegitimate.[2] The species was first legitimately named in 1898 by Friedrich Kraenzlin as Peristylus secundiflorus. It was later transferred to Gymnadenia and then to Neottianthe.[1] A molecular phylogenetic study in 2014 found that species of Neottianthe, Amitostigma and Ponerorchis were mixed together in a single clade, making none of the three genera monophyletic as then circumscribed. Neottianthe and Amitostigma were subsumed into Ponerorchis, with this species becoming Ponerorchis secundiflora.[3]


Ponerorchis secundiflora is native to the Himalayas, including Tibet, Nepal and the Assam region. Its range extends to Myanmar and south-central China (west Sichuan and north-west Yunnan).[1]
