It may be confused with the previous two species as already pointed out above. Rechinger f. (l.c. 304 and 305) included Duthie 8589 under this species as well as under Erysimum repandum. Its slightly smaller flowers, short, erect, often sub-appressed or ascending siliquae with only 2-partite hairs are distinctive.
