Sterigma contortuplicatum Boiss. in Ann. Sci. Nat., Bot. ser. 2, 17: 387. 1842.

Type: “[Aucher-Eloy] Absque numero, in provinciâ Aderbidjan”.

Holotypus: IRAN: “Aderbidjan”, s.d., Aucher-Eloy s.n. (P [P00741726]; iso-: G-BOIS [G00332242]) (Fig. 14, p. 58) .

= Sterigmostemum incanum M. Bieb., Fl. Taur. -Caucas. 3: 444. 1819.

Note. – Although JACQUEMOUD (1988: 76) cited the P material as the lectotype, it should be recognized as the holotype because Boissier annotated it (Fig. 14, p. 58) and took the fragmentary G-BOIS piece from it. Therefore, BOISSIER (1842a) used that Paris unicate in the species description.
