Primula tsaiana (Primulaceae), a New Species from Yunnan, China, and a New Synonym of P. wenshanensis

Abstract

Primula nghialoensis D.W.H. Rankin (Primulaceae) is reduced to the synonym of P. wenshanensis Chen & C.M. Hu. A new species, P. tsaiana G. Hao & Y. Xu, from southeastern Yunnan, China, is described and illustrated. It is similar to P. wenshanensis and P. petelotii, but can be distinguished from them by its distinct rhizome, leaf venation pattern, and shortly lacerated corolla lobes.
