Morphology

Erysimum collinum is a biennial species. Plants are typically branching at the base, with 1-7 stems at the time of flowering. Leaves (length 14-50 mm, width 2-11 mm) are covered in hairs and are narrower at the base. Flowers are yellow with glabrous petals 6–11 mm long and 2-4 mm wide. There are 30-60 flowers in the main raceme. Seed pods are 56-95 mm long, 1.3-2 mm wide, square with non-obvious edges, and aligned parallel to the flower stalk. Flower stalks are rounded and 500 – 820 mm tall at the time of seed set.[3][5][10]

Occurrence

Erysimum collinum is native to southeastern Russia, Armenia, Turkey, Georgia, Azerbaijan, Iraq, and Iran, where it grows at altitudes from 700 to 1390 m.[5] Habitats where E. collinum is found include cultivated fields, river banks, and rocky areas.

Taxonomy

In a 2014 taxonomic revision, E. aucherianum, E. gayanum, E. gracile, and E. passgalense are considered to be the same species as E. collinum.[3] The revised species has both diploid (2n = 14) and hexaploid (2n = 42) members.[5] Based on sequence comparisons of expressed genes in 48 Erysimum species, E. collinum is most closely related to E. crassipes and E. crassicaule.[11]

Chemical defenses

The genus Erysimum is known for containing two major classes of defensive metabolites: glucosinolates, which are characteristic of all Brassicaceae, and cardiac glycosides (cardenolides), which are found only within the genus Erysimum.[12] However, unlike other analyzed members of the genus Erysimum, E. collinum contains only trace amounts of cardiac glycosides (cardenolides).[11] Nevertheless, extracts of E. collinum showed some inhibitory activity of the mammalian sodium-potassium ATPase pump (Na+/K+-ATPase), the main molecular target of cardenolides.[11]

The most abundant glucosinolate in E. collinum is glucoerypestrin (3-methoxycarbonylpropyl glucosinolate),[11] which has been reported only within the genus Erysimum,[13] including also in the species E. repandum (syn. E. pulchellum), E. odoratum, and E. ochroleucum.[11][13][14][15] Other glucosinolates found in E. collinum are indol-3-ylmethyl glucosinolate, 4-methoxyindol-3-ylmethyl glucosinolate, 3-methylsulfinylpropyl glucosinolate, 2-methylpropyl glucosinolate, and n-methylbutyl glucosinolate.[11]
