When describing Delphiniumcamptocarpum, Ledebour quoted Karelin’s gathering “ad latus orientale maris caspii” and described two varieties (D.camptocarpumvar.dasycarpum and D.camptocarpumvar.leiocarpum) according to the presence or not of indumentum on the follicle, but without citing any material. Several of Karelin’s gatherings of D.camptocarpum were found at LE. Four of them belong to Ledebour’s herbarium (two can be attributed to D.camptocarpumvar.leiocarpum, but it is unclear for the other two) and can be regarded as type collection. We synonymise D.camptocarpumvar.leiocarpum under the autonym.

Nevski’s indication (1937) that the type is housed at LE can be considered a first-step lectotypification, and we designate here the specimen LE00050875 as the second-step lectotype.
