Nomenclature

Note: 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 (cf. Mitchell & Tucker, 1997).
