摘要：

Saxifraga sunhangiana, a new species of the genus Saxifraga sect. Irregulares (Saxifragaceae) from Gansu, China, is described and illustrated. This species is distinguishable by its abaxial leaf surface with singularly long white villous hairs and rather long rhizomes. Morphological and molecular data indicate that S. sunhangiana belongs to S. sect. Irregulares, and closely related to S. rufescens. The new species differs from S. rufescens by its terminal flower with two elongated, fusiform-lanceolate petals and leaves with glabrous petiole.
