Koniga arabica Boiss., Diagn. Pl. Orient. 8: 26. 1849.

 Lobularia arabica (Boiss.) Muschl., Man. Fl. Egypt 1: 421. 1912.

Type: “Hab. in desertis Aegypti (Aucher), Arabiae petreae ad meridiem urbis Gaza in arenosis (Boiss.)”.

Lectotypus (first step designated by BORGEN, 1987: 66; second step designated here): EGYPT: sine loco, 1837, AucherEloy 264 (G-BOIS [G00332424]; isolecto-: G [G00371856], K [K000230466], P [P00868524]) . Syntypus: PALESTINE: “Désert frontières de Palestine”, IV–V.1846, Boissier s.n. (G-BOIS [G00332423]) .

Notes. – BORGEN (1987) selected one of the two syntypes cited by BOISSIER (1849), Aucher-Eloy 264, as the lectotype collection and indicated that the G-DC specimen is the lectotype. The G-DC abbreviation stands for the Prodromus herbarium, which does not have any of Aucher-Eloy collections. Instead, what she likely meant was G00371856, which has a label of Candolle’s herbarium, and such collections are part of the general herbarium (G).

However, this duplicate was not annotated by Boissier who described the species solely on the specimen in G-BOIS. Therefore, a second-step lectotypification is proposed here to solve this problem.
