Capparis pubifolia B. S. Sun is reported here as a new addition to the flora of Vietnam. It is morphologically allied to C. sikkimensis Kurz but differs due to the gray-yellow color of the hair of the twigs, having more secondary veins on the leaf, trichomes on both surfaces of the petal, and a globose shape of the fruit. Thus far, it was only reported in the Guangxi and Yunnan areas of China. A description, a line drawing and color photographs are provided for species identification. Furthermore, a comparison of the diagnostic characters with those of related species is made.
