Sinocrassula cuonaensis (Crassulaceae), a new succulent species from Southern Xizang, China

Sinocrassula cuonaensis, a new species of Crassulaceae from southern Xizang, is described and illustrated based on molecular and morphological evidence. Phylogenetically, it is sister to S. densirosulata with robust support. Morphologically, this new species is similar to S. indica var. viridiflava, S. densirosulata, and S. jiaozishanensis in having glabrous indumentum and long inflorescences, but it can be easily distinguished by its rosulate, thick, and near-cylindrical basal leaves, greenish white flowers, and sub-rectangular nectar scales.

A key for identification of the genus, including the new species, is provided.
