This species was mistakenly treated as a synonym of Euonymus nitidus in a recent revision (J. S. Ma, Thaiszia 11: 1-264. 2001). Further collections from S Guangdong confirm that this is an unusual species in the genus, with winglike angles and more than 2 ovules and seeds per locule; this differs from most of the species in the section.
