Saxifraga zhiminiae (Saxifragaceae), a new species from Xizang, China

Saxifraga zhiminiae, a remarkable new species of the genus Saxifraga sect. Ciliatae (Saxifragaceae), is described from Xizang, China. This new species morphologically differs from all known species of sect.

Ciliatae by its plant glabrous (except for glandular cilia on the sepal margins), leaf blade abaxially red and petals pink with a dark red base adaxially. Morphological comparison and molecular evidence from chloroplast genomes indicate that S. zhiminiae belongs to sect. Ciliatae subsect.

Hirculoideae and is closely related to Saxifraga diversifolia, but it can be easily distinguished by its glabrous habit and striking petal colouration.
