Abstract

Abstract: Saxifraga banmaensis J. T. Pan and S. dingqingensis J. T. Pan, two species of the genus Saxifraga (Saxifragaceae) from China, are described and illustrated. Of these, S. banmaensis J. T. Pan is known only from Banma County, Qinghai Province, and related to S. umbellulata Hook. f. & Thoms. (including varieties), but differs by having sepals cartilaginous-mucronulate at apex, and petals linear, not pandurate-oblong to pandurate, base not unguiculate. S. dingqingensis J. T. Pan occurs in Dingqing County, Xizang, and is similar to S. llonakhensis W. W. Smith, but differs by having sepals 3-veined, veins confluent at apex, petals 8-callose, 4-5-veined, base truncate or subauriculate. Both species are endemic to China, and belong to subsect. Rosulares Gornall.

Key words: Saxifraga, Saxifraga banmaensis J. T. Pan, Saxifraga dingqingensis J. T. Pan, Saxifragaceae, new species, Qinghai, Xizang, China
