8EA737549A59595AAD1F4B4FB1F895E6.taxon	description	Diagnostic description. Sinocrassula cuonaensis is similar to S. indica var. viridiflava, S. densirosulata, S. jiaozishanensis in having glabrous plant and long inflorescence, but its rosulate, thick, and near-cylindrical basal leaves (vs. rosulate, spatulate, not rosulate, respectively) and greenish white flowers (vs. greenish yellow, purplish red, reddish purple, respectively) differ from the others. Besides, this new species has sub-rectangular nectar scales that are similar to S. indica var. viridiflava (vs. near-rectangular oblong) and S. densirosulata (vs. spatulate-quadrate) but different from S. jiaozishanensis (vs. oblong) (Table 2).	en	Qiu, Xiang-Dong, Shi, Jia-Jing, Feng, Ya-Lin, Zhang, Feng-Di, Wang, Sheng-Wei, Wei, Neng, Wang, Qing-Feng (2025): Sinocrassula cuonaensis (Crassulaceae), a new succulent species from Southern Xizang, China.

8EA737549A59595AAD1F4B4FB1F895E6.taxon	distribution	Distribution and habitat. Sinocrassula cuonaensis is currently known only from southern Xizang, China (as depicted in Fig. 4). This new species was found on moist rocks along slopes in the valley at elevations of 2500 – 2850 m. The general vegetation condition of the habitat is characterized by the tree layer dominated by Pinus wallichiana A. B. Jacks., Picea spinulosa (Griff.) A. Henry, and Cotoneaster sp.; the shrub layer is dominated by shrubs of the families Urticaceae and Asteraceae; and the herb layer is primarily composed of Pteridium latiusculum (Desv.) Hieron., Corallodiscus sp., and Impatiens scabrida DC. Additionally, due to the steep topography, these rock walls are less disturbed by human activities.	en	Qiu, Xiang-Dong, Shi, Jia-Jing, Feng, Ya-Lin, Zhang, Feng-Di, Wang, Sheng-Wei, Wei, Neng, Wang, Qing-Feng (2025): Sinocrassula cuonaensis (Crassulaceae), a new succulent species from Southern Xizang, China.
