Summary The nomenclatural problems of three genera of Mesembryanthemaceae, Hymenogyne Haw., Thyrasperma N. E. Br., and Apatesia N. E. Br. are due to the fact that the herbarium sheets on which the description of the genus Thyrasperma was based involve specimens belonging to the other two genera. The names Hymenogyne and Apatesia are determined to be correct; after lectotypification, Thyrasperma is a younger synonym of Hymenogyne.
