Pueraria grandiflora (Fabaceae), a new species from Southwest China

Abstract

A new species, Pueraria grandiflora, (Fabaceae, Phaseoleae), is described and illustrated. It resembles Pueraria tuberosa, but differs in lobed leaflets, larger flowers, single or once branched inflorescences, and flowering and fruiting season. This species is only known from dry-hot valleys in Sichuan and Yunnan, and is rare and narrowly distributed.
