Morphological characters and geographic distribution are the same as those of the family.

"Stachyurus calcareus" (H. T. Chang & Z. R. Xu, Acta Sci. Nat. Univ. Sunyatseni 1986(2): 98. 1986) was not validly published because no type was indicated. It was described from Guizhou as similar to S. oblongifolius, which is a synonym of S. yunnanensis in the present treatment.
