The protologue of Sisymbrium brevipes included two elements, of which Karelin & Kirilov 106 (LE) is the type of the species name, and it definitely belongs to the taxon currently known as Neotorularia brevipes (see below). The other element, Karelin & Kirilov 1240 (LE), which is a Malcolmia with twisted fruit and connivent stigma, was cited by Karelin and Kirilov under an unnamed variety, which is the basis of the name M. karelinii.
