AL-Shehbaz, Ihsan A. & Barriera, Gabrielle, 2019, Typification of Edmond Boissier’s Cruciferae (Brassicaceae) names enumerated in Flora Orientalis, Boissiera 72, pp. 1-193 : 108-109

Draba edmondii Al-Shehbaz , nom. nov.

 Draba macrocarpa Boiss. & Heldr. in Boiss., Diagn. Pl. Orient. 8: 28. 1849 [nom. illeg.] [non Adams].

 Erophila macrocarpa Boiss., Fl. Orient. 1: 304. 1867.

Type: “Hab. in collibus maritimis propè Smyrnam in consortio Dr. vernae Febr. et Mart. (Heldr.) ”.

Holotypus: TURKEY: “in collibus ad littora maris prope Smyrnam”, 26.II.1846, Heldreich 1297 ( G-BOIS [ G00332463 ]; iso-: B [ B000522043 ], E [ E00373101 ], G [ G00446214 , G00446215 ], GOET [ GOET002573 ], K [ K000697635 , K000697636 , K000697637 ], P [ P06650499 ], W [ W0075600 , W0075601 ]) .

Etymology. – The species is named after the renouned Swiss botanist Pierre-Edmond Boissier (see introductory part of this paper).

Notes. – Except for the holotype in G-BOIS and isotype at W [ W0075601 ], all other isotypes were distributed as exsiccatae without a collection number .

HALÁCSY (1900: 102) recognized this taxon as a variety of Draba verna , whereas both WALTERS (1964: 57) and COODE & CULLEN (1965) maintained it as a subspecies of Erophila verna . As shown above, Erophila is perfectly nested within Draba and, therefore, the plant should be renamed when maintained as a distinct species of Draba .

Draba edmondii is unique among all the taxa previously assigned to Erophila and can be readily distinguished from them by having linear to linear-lanceolate (vs orbicular to ovate or elliptic) siliques (6–)7–10 times (vs equaling or to 4.5 times) longer than broad and with parallel (vs not parallel) margins, as well as fruiting pedicels shorter or rarely subequaling (vs longer) than fruit. It is distributed in Greece, the eastern Aegean Islands, and western Turkey.
