Heldreichia longifolia Boiss. in Ann. Sci. Nat., Bot. ser. 2, 17: 187. 1842.

 Lepidium longifolium (Boiss.) Al-Shehbaz in Novon 12: 8. 2002.

Type: “[Aucher-Eloy] N. 320 in monte Zerdkou”.

Lectotypus (designated here): IRAN: “in Mte. Zerde”, s.d., Aucher-Eloy 320 (G-BOIS [G00150398]; isolecto-: BM [BM001254105], G [G00096409], K [K000484134], MPU [MPU023096], P [P01817522, P01817523, P06648212]) .

Notes. – The species name needed lectotypification because Boissier based the description on the duplicates in G-BOIS and P06648212 which he annotated.

The listing by AL-SHEHBAZ et al. (2002: 8) of the holotype at G is incorrect and resulted from overlooking BOISSIER (1841a).
