There are only a few collections available for this species, and the type has the only flower. The type was collected between Yen Yuen (Yanyuan, Sichuan) and Yungning (Ningliang, Yunnan), from the Sichuan side, according to Handel-Mazzetti’s description and the type record. The leaves appear clustered on the young twigs, and the flowers larger than the other small Euonymus species; the pale yellow flower color is also distinct.
