Albuca toxicaria (C.Archer & R.H.Archer) J.C.Manning and Goldblatt in Manning et al. in Taxon 58: 92 (2009). Type: South Africa, Western Cape, 'Beaufort West Dist., Farm RystKuil 351', 08 Oct 1983, Retief & Reid 239 (PRE [flowering plants and sterile plants only, excluding the fruiting plant and detached infructescence], lecto.!, designated here).

Note: This diminutive species was described in Ornithogalum subg. Urophyllon (Salisb.) Baker on account of its evidently spurless bracts, free tepals with median longitudinal stripe, erect style with small stigma, large tricostate capsules with adherent perianth and large flat seeds (Archer & Archer 1999). The very small bracts are, however, anomalous here. The species was transferred to Albuca subg. Namibiogalum (U.Mull.-Doblies & D.Müll.-Doblies) J.C.Manning & Goldblatt, along with other species of Ornithogalum with similar floral and fruit morphology, by Manning et al. (2004) in their revised generic classification of subfamily Ornithogaloideae. Recent collections of the species that we have seen, however, confirm the initial conclusions of A.A.Obermeyer that it is in fact a species of Drimia. This is clear from the presence of a short but evident spur on the lowermost bracts of some paratype and other specimens, the uni-nerved tepals in the type and all other collections, and the winged seeds with loose testa. Examination of the type, which comprises several plants, shows it to be a mixed gathering, with the flowering and sterile plants conforming to the protologue description and accompanying illustration but the fruiting material representing a species of Albuca, as is evident from the large bracts, multi-nerved tepals and prismatic style. We accordingly exclude the fruiting material and lectotypify the name against the flowering and sterile material only (Turland et al. 2018: Art. 9.14). The relationships of the species in Drimia are not immediately apparent, but the congested, relatively long-lived flowers without bracteoles and the moderately large capsules with perianth persisting below the developing fruit for somewhile suggest a possible relationship with D. sanguinea (Schinz) Jessop (sect. Macrocentrae).
