摘要	Two new species, Saxifraga xiaozhongdianensis J. T. Pan and S. ludingensis J. T. Pan, from the Saxifragaceae in China are described and illustrated. Of these, S. xiaozhongdianensis is endemic to Zhongdian, Yunnan, and is related to S. brachyphylla Franchet. It differs from S. brachyphylla in the sepals adaxially dark brown glandular-villose and the petals basally subauriculate. Saxifraga ludingensis occurs in Luding, Sichuan, and is very similar to S. egregioides J. T. Pan and S. stellariifolia Franchet. It differs from S. egregioides in the stems brown glandular-villose, the cauline leaves adaxially brown glandular-villose, the sepals spreading in anthesis and abaxially brown glandular-villose, and the petals 5-veined. It differs from S. stellariifolia in the leaves cordate and abaxially glabrous, the sepals abaxially brown glandular-villose, and the petals 4-callose and 5-veined. Saxifraga xiaozhongdianensis and S. ludingeasis are apparently endemic to western China and belong to Saxifraga sect. Ciliatae Haworth, emend. J. T.
