The spelling Euonymus has been conserved against the originally used Evonymus. Also the Spermatophyta Committee rejected (Taxon 49: 270-271. 2000) a proposal to conserve the gender of Euonymus as feminine. The Code currently regards the name to be masculine since it lists the type as E. europaeus, and the Committee decided not to amend this usage.
The name Euonymus ser. Orientales (Loes., Nat. Pflanz., ed. 2 (Engler & Prantl) 20b: 117. 1942), nom. inval. is invalid as no Latin description or diagnosis was provided with the original publication. Also series is given as a rank above section. The name cannot be used.

Proposes replacing the sub-familial taxa with only Euonymus Sect. Echinococcus (with spiny fruits) and Euonymus Sect. Kalonymus (with winged fruits). Also presents evidence that the inclusion of Glyptopetalum renders Euonymuss.l. monphyletic.
