Brassica persica Boiss. & Hohen. in Boiss., Diagn. Pl. Orient. 8: 26. 1849.

Type: “ Br. elongata Boiss. Ann. Sc. Nat. 1842 non Ehrh. Hab. in Mesopotamiâ Aucher l. cit.! [n. 253] Persiâ Aucher loc. cit.! [n. 219] inter segetes ad Teheran Kotschy Nº 32”.

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.
