Erysimum redowskii, synonym Erysimum pallasii, known as Pallas' wallflower, is a low shrub or mid shrub species from the Arctic. It has purple flowers that do not reflect UV.[2]

Taxonomy

Erysimum redowskii was first described by Johann Anton Weinmann in 1810.[3] A description of Cheiranthus pallasii was first published by Frederick Traugott Pursh in 1813.[4] It was transferred to Erysimum as Erysimum pallasii by Merritt Lyndon Fernald in 1925.[5] E. pallasii was considered to be a synonym of E. redowskii by Adolf Polatschek in 2010 and 2012 listings of Erysimum species.[6][7] The synonymy is accepted by Plants of the World Online, as of April 2021.[1]

Distribution

This wallflower has a circumpolar Arctic distribution. It is widespread in the Canadian Arctic Archipelago, and common in Greenland, Northwest Canada[where?] and Alaska.

Ecology

This species seems to be apomictic, since it is scarcely visited by insects and seed production is independent of flower visitors.[8]
