Abstract
Five species recently described in the genus Geschollia Speta (Hyacinthaceae:Urgineoideae) are transferred to Drimia Jacq. ex Willd. as D. brachyandra(Mart.-Azorín et al.) J.C.Manning & Goldblatt, D. globuligera (Mart.-Azorín et al.)J.C.Manning & Goldblatt, D. longipedicellata (Mart.-Azorín et al.) J.C.Manning& Goldblatt and D. prolifera (Mart.-Azorín et al.) J.C.Manning & Goldblatt, withthe new name D. zebrinella J.C.Manning & Goldblatt provided for G. zebrinaMart.-Azorín et al. since that epithet is pre-occupied in Drimia. Austronea patersoniae Schönl. ex Mart.-Azorín et al. is treated as a synonym of D. chalumnensis A.P.Dold & E.Brink. The two names Urginea amboensis Baker and Albuca reflexa K.Krause & Dinter are formally placed in synonymy under Drimia zambesiaca (Baker) J.C.Manning & Goldblatt to accord with the current taxonomy. The recently described monotypic genus Triandra Mart.-Azorín et al. is also included in Drimia and the necessary transfer of T. pellabergensis Mart.-Azorín et al. to Drimia is effected, along with the second known locality for the species, representing a significant range extension. A total of 80 species of Drimia are now recognised in southern Africa. Updated identification keys to the species in sections Capitatae, Ledebouriopsis, Macrocentrae, Physodia and Thuranthos are provided.
Highlights
The most recent taxonomic review of the species of Drimia Jacq. ex Willd. in southern African recognised 70 species distributed among 19 sections (Manning & Goldblatt 2018)
Note: These three names were treated as synonyms of Drimia indica (Roxb.) Jessop by Manning and Goldblatt (2018) following conventional usage but since the realisation that D. indica is restricted to the Indian subcontinent (Martínez-Azorín et al 2018b; Yadav et al, 2019), the earliest available name for the African taxon as currently circumscribed is Drimia zambesiaca and the other two names are placed in synonymy
Bulb scales cohering; leaves rounded beneath; pedicels 20–30 mm long at anthesis; filaments ±
Summary
The most recent taxonomic review of the species of Drimia Jacq. ex Willd. in southern African recognised 70 species distributed among 19 sections (Manning & Goldblatt 2018). A few nomenclatural changes were made by Martínez-Azorín et al (2019d) and Manning (2019) to the taxa that were recognised by Manning and Goldblatt (2018) In view of both the increase in the number of species and the changes to the nomenclature of others, it seems useful to provide updated sectional keys to the species that have been affected, to facilitate both http://abcjournal.org |. Their identification and the correlation of the taxa with those enumerated by Manning and Goldblatt (2018). The system of numbering of species used in Manning and Goldblatt (2018) is retained, with new species inserted into that system with decimal points
