Phenology: Flowering period: February to April; fruiting period: September to November.  

Distribution and Habitat: This species distributes in Tian'e County, Guangxi Zhuang Autonomous Region, and Luodian County, Guizhou Province. It grows in the understory of evergreen broad-leaved forest on limestone mountains at elevations of 350–450 m.  

Note:C. tianeensis should be recognized as a distinct species. It differed from C. huana primarily in the flowering period from February to April (vs. mid-October to December),and the color of annual branch ranged from light red to burgundy(vs. grey),and its fruit was oblate triangular spherical-shape with pericarp of 1-3 mm thick(vs. fruit oblate spherical-shape with pericarp of 9-11 mm thick) .
