Notes.

In the protologue of D. flavum , Candolle (1817) described two varieties (var. Delphinium flavum velutinum and var. Delphinium flavum glabrum ) based on the pubescence and the bracteole position on the pedicel. We synonymize here D. flavum var. velutinum with the autonym. Candolle indicates that he saw the specimen in Olivier’s herbarium (now at P), whereas we found at G-DC a duplicate received in 1822. At P, we found two sheets of the Olivier and Bruguière’s gathering. It is not sure whether Candolle annotated these sheets. The specimen P00197330 bears the label "dans les lieux incultes steriles de Bagdad a Kermancha" and a mixture of both varieties (the specimen in the bottom right corner corresponds to D. flavum var. glabrum ). We designate as lectotype the six other specimens on this sheet.

A single and fragmentary specimen of D. deserti , labelled " D. deserti " by Boissier, was found in G-BOIS (G00788308) and probably came from a P duplicate. We designate as lectotype of D. deserti the specimen P00197319, the only one bearing a priori an annotation from Boissier.
