Isatis campylocarpa Boiss. in Ann. Sci. Nat., Bot. ser. 2, 17: 203. 1842.

Type: “[Aucher-Eloy] N. 204, Persia ”.

Holotypus: IRAN: sine loco, s.d., Aucher-Eloy 204 (P [P00741422]; iso-: G-BOIS [G00332621], W [W0050810]) .

Notes. – The only material of the species in the Geneva herbaria is a fragment consisting of a tiny branch with two fruits and empty packet. Boissier annotated P00741422, as “ Isatis campylocarpa! Boiss. ”, from which he took that tiny branch.

The Paris material is the only unicate that BOISSIER (1842b) used in his full description of the species, including details on the plant habit, basal leaves, flowers, and infructescence, all of which characters not found on the G-BOIS material. Therefore, the P unicate is recognized as the holotype.
