Aethionema stenopterum Boiss.

AL-Shehbaz, Ihsan A. & Barriera, Gabrielle, 2019, Typification of Edmond Boissier’s Cruciferae (Brassicaceae) names enumerated in Flora Orientalis, Boissiera 72, pp. 1-193 : 144

Aethionema stenopterum Boiss. in Ann. Sci. Nat., Bot. ser. 2, 17: 192. 1842.

Type: “[Aucher-Eloy] N. 341, Akdagh; 4129, Persia ”.

Lectotypus (first step designated by Al-Shehbaz in MOAZZENI et al., 2018: 258; second step designated here): IRAN: “ Ispahan ”, s.d., Aucher-Eloy 4129 ( P [ P00432260 ]; isolecto-: G [ G00002108 ], G-BOIS [ G00154001 ], P [ P01817632 ]) . Syntypus: TURKEY: “Ak Dagh”, s.d., AucherEloy 341 ( G [ G00002107 ], K [ K000618646 ], P [ P00428093 , P01817633 ]) .

Notes. – Label of the G-BOIS isolectotype was handwritten by Boissier, and its fragmentary flowering branch taken from P00432260 that Boissier annotated.

The species epithet is named after the fruiting material on the P specimen above. Al-Shehbaz (in MOAZZENI et al., 2018) selected Aucher-Eloy 4129 as the lectotype collection, but he designated the G-BOIS rather than the P fruiting specimen as the lectotype. That erroneous handling is corrected here by a second-step lectotypification.

As noted by HEDGE (1968: 106), the syntype (Aucher-Eloy 341) was cited by BOISSIER (1867a: 346), under A. thesiifolium instead of A. stenopterum .

HEDGE (1968: 103, 106) separated Aethionema stenopterum from A. virgatum solely by having style exserted vs included or subequalling the apical fruit sinus, but that difference alone is tenuous at best, and further morphological studies are needed to separate these two species which are clearly unrelated based on molecular phylogenetic studies by MOHAMMADIN et al. (2017).
