MANNING, John C.. New synonyms and combinations in Drimia Jacq. (Hyacinthaceae) in southern Africa. Bothalia (Online) [online]. 2019, vol.49, n.1, pp.1-5. ISSN 2311-9284.  http://dx.doi.org/10.4102/abc.v49i1.2412.

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
