Comment: since a description or diagnosis was not provided by Purchas & Ley, this variety is solely based on the cited "Brassica polymorpha, subspecies campestris, of Eng. Bot., Ed. iii", which itself is based on B. campestris L. It cannot be considered to be based on B. asperifolia var. sylvestris Lam. (Encycl. 1:746. 1785), as assumed by Thellung (in Hegi, Ill. Fl. Mitt.-Eur. 4(1):259. 1918), since Lamarck excluded the Linnaean type from his taxon by including it elsewhere (B. perfoliata var. lutea Lam. p. 748) and the two names cannot be homotypic. Since the autonym B. campestris var. campestris already existed (at least since 1854 in Hartman, Handb. Skand. fl. ed. 6:110) and should have been adopted at this rank, var. sylvestris is illegitimate (Shenzhen ICN Art. 52). No description or diagnosis or reference to one was provided by Briggs in 1880.
