Abstract: Sinocrassula represents the medium‐sized Asian genus within Crassulaceae, exhibiting maximum species diversity in China. This study presented the first comprehensive phylogenetic analyses of Sinocrassula, utilizing both sanger data and next‐generation sequencing data. We confirm that three populations of Sinocrassula from Yunnan Province represent two distinct new species, and we described them as S. crassifolia Chao Chen, Jing Zhao & J. Guan Wang (including two populations) and S. yongshengensis Chao Chen & J. Guan Wang (one population). Morphologically, these two new species resemble S. indica var. obtusifolia. However, phylogenetic analyses place these two new species closer to S. adpressa. According to IUCN guidelines, the two new species are preliminarily assessed as "Data Deficient (DD)." The findings hold significant implications for understanding the flora of the Himalaya‐Hengduan Mountains (HHM) region and lay the groundwork for future development of ornamental and medicinal resources in the family of Crassulaceae.
