Lectotypus (designated here): IRAN: “Inter segetes prope urbem Teheran ”, 17.IV.1843, Kotschy 32 (G-BOIS [G00332651]; isolecto-: BM [BM000593489, BM001254154, BM001254155], G [G00446303, G00446304, G00446305], G-BOIS [G00332653], H [H1511099], K [K000653836, K000653837], KW [KW000127943], MO [MO3729750], P [P00580389, P04687356, P05325349, P05325351, P05325354]) . Syntypus: IRAN: sine loco, s.d., Aucher-Eloy 219 (BM [BM000587780], G [G00446302], G-BOIS [G00332649], K [K000618652], P [P05325380, P05325381, P05325382]) .

= Brassica elongata Ehrh., Beitr. Naturk. 7: 159. 1792.

Notes. – No specimens of Aucher-Eloy 253 were found in the Geneva and Paris herbaria, though BOISSIER (1867a: 268, 394) listed that collection number under both Alyssum alpestre var. suffrutescens and Brassica elongata var. integrifolia .

Both P05325380 and P05325382 were annotated by Boissier as “ Brassica elongata W.K.”.

The species was reduced by BOISSIER (1867a: 394) to synonymy of the previous entry.

Brassica persica has recently been transferred by GERMAN (2015) to Guenthera, a genus resurrected by GÓMEZ-CAMPO (2003) to include nine species that he separated from Brassica on the basis of morphological characters and chromosome numbers.

As shown by WARWICK & SAUDER (2005) and WARWICK & HALL (2009) nuclear and chloroplast markers did not provide support for the monophyly of Guenthera sensu Gómez-Campo, though the chloroplast data by ARIAS & PIRES (2012) showed that the four Guenthera species they examined formed a wellsupported monophyletic clade. While Guenthera might be the ultimate generic home for these species, they are temporarily retained in Brassica, with the hope of seeing a more comprehensive, genus-wide taxonomic adjustments for all species currently assigned to the latter genus.
