Brassica nivalis Boiss. & Heldr. in Boiss., Diagn. Pl. Orient. ser. 2, 1: 32. 1854. Type: “Hab. in rupibus ad nives Olympi Thessali rara (Heldr. Julio 1851)”. Holotypus: GREECE: “In rupibus ad nives Olympi Thessaliae”, 24.VII.1851, Heldreich 2559 (G-BOIS [G00332641]; iso-: WU [WU0076059]). Notes. – The systematic position of Brassica nivalis is controversial, and it has been assigned to at least five genera of the tribe Brassiceae. Although some authors placed the species in Coincya Rouy (Greuter & Burdet in GREUTER & RAUS, 1983; GREUTER et al., 1986; TAN, 2002) or in Guenthera Andrz. (GÓMEZ-CAMPO, 2003, see comments under Brassica persica), it is tentatively retained in Brassica, as done by LEADLAY & HEYWOOD (1990), JALAS et al. (1996), and WARWICK & AL-SHEHBAZ (2006). The species does not fit in Coincya because it drastically differs in floral morphology, geography, and chromosome numbers.
