Platanthera whangshanensis (S.S. Chien) Efimov, a Forgotten Orchid of Chinese Flora.

Platanthera whangshanensis, a forgotten species of the Chinese flora, is described and illustrated. Originally it was described as a member of genus Perularia, and a corresponding new combination is here proposed. In the «Flora of China» this taxon was treated under the name Platanthera tipuloides, which is in turn a species that is absent from the flora of subtropical China. The localities of true Platanthera tipuloides may be found only in the north-west of the country. A doubtful record of Platanthera tipuloides from Liaoning Province is discussed.
