Background Ongoing systematic studies in the African flora necessitate periodic nomenclatural adjustments and corrections. Objectives To effect requisite nomenclatural changes. Method Relevant literature was surveyed and relevant material was examined. Results Nomenclatural adjustments are provided for recently described taxa of Hyacinthaceae subfamily Urgineoideae in order to accommodate them in the alternative classification system in use in South African herbaria. Conclusion A broadly circumscribed Drimia Jacq. has the advantages of nomenclatural stability and utility. The newly described segregate genera Austronea Mart.-Azorín et al. and Zingela N.R.Crouch et al. are formally included in Drimia , and A. densiflora Mart.-Azorín et al., A. hispidoplicata Mart.-Azorín et al. and A. pinguis Mart.-Azorín et al. are transferred to that genus as D. densiflora (Mart.-Azorín et al.) J.C.Manning & Goldblatt, D. hispidoplicata (Mart.-Azorín et al.) J.C.Manning & Goldblatt and D. pinguis (Mart.-Azorín et al.) J.C.Manning & Goldblatt, respectively, whereas A. grandiflora Mart.-Azorín et al. and A. linearis Mart.-Azorín et al. are treated as synonyms of D. vermiformis J.C.Manning & Goldblatt; A. olifanta Mart.-Azorín et al. is treated as a synonym of D. barkerae Oberm. ex J.C.Manning & Goldblatt; and A. papillosa Mart.-Azorín et al. and A. pygmaea (A.V. Duthie) Mart.-Azorín et al. are treated a synonyms of D. virens (Schltr.) J.C.Manning & Goldblatt. Zingela pooleyorum N.R.Crouch is considered to be conspecific with Urginea zambesiaca Baker, for which the new combination D. zambesiaca (Baker) J.C.Manning & Goldblatt is provided. The combination D. zebrina (Mart.-Azorín et al.) J.C.Manning & Goldblatt is provided for an allied species. Examination of recent collections of Ornithogalum toxicarium C.Archer & R.H.Archer confirms that it is actually a species of Drimia and it is accordingly transferred to that genus as D. toxicaria (C.Archer & R.H.Archer) J.C.Manning & Goldblatt.

The correct author citations for several names in the genera Drimia (Hyacinthaceae) and Eriospermum (Ruscaceae) that were invalidly published by N.J. Jacquin are provided. The later validation dates for these names do not have implications for their nomenclatural priority. [ABSTRACT FROM AUTHOR]

The invalidly published name Massonia sect. Whiteheadia (Harv.) J.C.Manning is validated. [ABSTRACT FROM AUTHOR]
