Lepidium propinquum var. auriculatum Boiss., Fl.

Lepidium propinquum var. auriculatum Boiss., Fl. Orient. 1: 357. 1867. Type: “Hab. in lapidosis humidis Armeniae ad Koschadara (Szow!)”. Holotypus: AZERBAIJAN: “In lapidosis secus rivulos Kotschadara”, 18.VII.1829, Szovits 537 (G-BOIS [G00330475]; iso-: LE, P [P05444762]). = Lepidium chalepense L., Cent. Pl. 2: 23. 1756. Notes. – The holotype is a collection folder of two sheets, of which one is unlabeled but with the same collection number. The P duplicate has the collector as Szovits s.n. THELLUNG (1906b: 89) recognized one of the holotype sheets as Lepidium draba var. auriculatum (Boiss.) Thell., and he annotated the other as var. propinquum. By contrast, MULLIGAN & FRANKTON (1962: 1425) transferred var. auriculatum to Cardaria propinqua (Fisch. & Mey.) N. Busch, though they did not typify it. Except for the presence of minute auricles on the cauline leaves, in nearly all other aspects, the plant is more at home in Lepidium propinquum, though the latter species has no auricles at all. Perhaps the taxon should be maintained infraspecific taxon of this species, as originally described by Boissier in Flora Orientalis, but the lack of sufficient material for this study prevented accepting such assignments.Published as part of AL-Shehbaz, Ihsan A. & Barriera, Gabrielle, 2019, Typification of Edmond Boissier's Cruciferae (Brassicaceae) names enumerated in Flora Orientalis, pp. 1-193 in Boissiera 72 on page 150, DOI: 10.5281/zenodo.763043
