The new combinations Colchicum burchellii (Baker) J.C.Manning & Vinn. and C. burchellii subsp. pulchrum (Schltr. & K.Krause) J.C.Manning & Vinn. are provided for the taxa currently known respectively under the names C. coloratum subsp. burchellii (Baker) J.C.Manning & Vinn. and C. coloratum J.C.Manning & Vinn., nom superfl.

Keywords: Africa; Androcymbium Willd.; nomenclature; taxonomy.




The circumscription of the genus Colchicum L. (Colchicaceae: Colchiceae) was substantially enlarged by Manning et al. (2007) to include the largely sub-Saharan Androcymbium Willd. on the basis of their molecular phylogenetic analysis showing that Colchicum (including Bulbocodium L. and Merendera Ramond) constituted a clade that was deeply nested within Androcymbium. This relationship and its taxonomic implications have been confirmed by subsequent analyses (Nguyen et al. 2013). At the time, Manning et al. (2007) provided the necessary combinations in Colchicum for the taxa previously treated in Androcymbium. It has emerged, however, that they erred in their treatment of the species A. burchellii Baker and A. latifolium Schinz (= A. pulchrum Schltr. & K.Krause) and this is corrected here.



Androcymbium burchellii Baker and A. latifolium Schinz (= A. pulchrum Schltr. ex K.Krause) were treated as two distinct species in A. series Therocymbia U.Müll.-Doblies & D.Müll-Doblies (Müller-Doblies & Müller-Doblies 1998, 2002). The two taxa appear to differ, however, solely in the colouring of the foliage leaves and the bracts, and A. latifolium was subsequently treated as a subspecies of A. burchelli under the name A. burchellii subsp. pulchrum (Schltr. & K.Krause) Pedrola et al. (2003). This taxonomy was followed by Manning et al. (2007) when they proposed new combinations for these taxa in Colchicum.

The two earlier names Colchicum latifolium Sibth. & Sm. (Sibthorp 1823) and C. pulchrum Herb. ex Baker (Baker 1879) preclude the transfer of both of these epithets to Colchicum (Turland et al. 2018: ICN, Art. 53.1) and Manning et al. (2007) accordingly proposed the replacement name C. coloratum J.C.Manning & Vinn. for the taxon, with the two subspecies coloratum and subsp. burchellii (Baker) J.C.Manning & Vinn. The replacement name C. coloratum for the combined taxon is, however, nomenclaturally superfluous if this subspecific taxonomy is followed since the name A. burchellii Baker (Baker 1874), as a synonym, is available as an earlier epithet and should have been used (Turland et al. 2018: ICN, Art. 7 7.4). The combination A. burchellii subsp. pulchrum (Pedrola et al. 2003) establishes the priority of this epithet at subspecific rank (Turland et al. 2018: ICN, Art. 11.2). The correct combinations are provided below.

Should the two taxa be treated as distinct species, however, then the combination C. coloratum J.C.Manning & Vinn. is available for the component that includes the type of A. pulchrum.
