Morphology and molecules support the new monotypic genus (Rhamnaceae) from south China.

, a new monotypic genus, along with the new species , is described from Guangdong Province, China. The combined features of inferior ovary, cylindrical drupaceous fruits and orbicular and dorsiventrally-compressed seeds with an elongate and pronounced basal appendage make the new genus significantly different from other genera of the family. In addition, its pollen morphology also showed great similarity to other species of this stenopalynous family. The molecular phylogenetic analysis, based on nuclear ribosomal internal transcribed spacer (ITS) and plastid intron spacer () DNA sequence data from the new genus and the other 375 species representing 58 genera of Rhamnaceae, indicates that is nested within the 'rhamnoid' group and sister to the tribe Rhamneae and then both sister to the tribe Maesopsideae. A taxonomic classification key to the 'rhamnoid' group is provided, based on morphological characters. A global conservation assessment is also performed and classifies as Near Threatened (NT).
