nevadense) is a biennial or perennial plant, generally branched with multiple flowering stems, usually less than 25 cm (10 in) high.

[3] A molecular phylogenetic study published in 2014 included four of the species, E. gomez-campoi, E. mediohispanicum, E. nevadense and E. rondae.

[4] Plants of the World Online divides Erysimum nevadense into six subspecies,[1] which Flora Iberica treats as separate species.

[8] Flowers are visited by many species of insects belonging to the order Hymenoptera, Diptera, Coleoptera, Lepidoptera and Heteroptera.

Most abundant flower visitors are Proformica longiseta (Formicidae), an ant species endemic to the Sierra Nevada and surrounding mountain ranges, Dasytes subaeneus (Melyridae), Malachius laticollis (Malachidae) and some species of beeflies belonging to the genus Bombylius and Parageron (Bombyliidae).
