Abstract

Background: Ongoing systematic studies of the African flora necessitate periodic nomenclatural adjustments and corrections.

Objectives: To effect requisite nomenclatural changes.

Method: Relevant literature was surveyed and type material located and studied.

Results: Nomenclatural corrections were published in Justicia L. (Acanthaceae), Babiana KerGawl. and Geissorhiza Ker Gawl. (Iridaceae) and Zaluzianskya F.W.Schmidt (Scrophulariaceae).

Conclusions: Firstly, a complete enumeration of all southern African species of Justicia was provided within the infrageneric classification for the genus accepted by Graham (1988) and later modified and expanded by Ensermu (1990) and Hedrén (1990). In this circumscription, Justicia includes such well-established segregates in an African context as Adhatoda Miller, Aulojusticia Lindau, Duvernoia E.Mey. ex Nees, Monechma Hochst. and Siphonoglossa Oersted.Both southern African species of Adhatoda were transferred to Justicia, as well as all of the southern African species of Monechma, with eight new combinations or replacement names provided. All species were placed to section within Justicia. Secondly, the type of Gladiolus nervosus Lam. (1788) was considered to be conspecific with Gladiolus strictus Aiton (1789) and is therefore the earliest available name for the species currently known as Babiana stricta (Aiton) Ker Gawl. The new combination Babiana nervosa (Lam.) Goldblatt & J.C.Manning was provided. Thirdly, Geissorhiza ornithogaloides has been regarded as a new species described by F.W. Klatt (1866) but the name should be treated as the combination G. ornithogaloides (Lichst. ex Roem. & Schult.) Klatt, based on Ixia ornithogaloides Lichst. ex Roem. & Schult.(1817a). Examination of the type showed that it is conspecific with Geissorhiza marlothii R.C.Foster (1941) and it is therefore the valid name for the taxon treated as G. ornithogaloides subsp. marlothii (R.C.Foster) Goldblatt. An epitype for the taxon was designated and the new combination G. ornithogaloides subsp. flava (Klatt) Goldblatt & J.C.Manning was provided for the taxon currently treated as G. ornithogaloides subsp. ornithogaloides. Lastly, Reyemia Hilliardwas reduced to a synonym of Zaluziaskya as sect. Reyemia (Hilliard) J.C.Manning & Goldblattand the new combination Zaluziaskya chasmanthiflora (Hilliard) J.C.Manning & Goldblatt was provided. A neotype was selected for Zaluziaskya nemesioides Diels.
