Summary
Rohdea harderi N. Tanaka, D. P. Hannon & Aver., a new species from northern Vietnam, is described and illustrated. It is most closely allied to R. verruculosa from SW China, but differs mainly by the narrower annular appendage at the throat of the perianth tube, explanate, subacute, crenulate, externally smooth perianth segments, smaller stigma and obovoid ovary. Its affinity is briefly discussed on the basis of floral traits. A key to the species known from Vietnam is also provided.
