| Distribution | Collected in 2 locations: Yancey County in 1958 by Ahles & Duke on a roadside SW of Burnsville; and Jackson County in 1968 by Leonard & Radford in a field NE of Cherokee. These specimens were originally thought to be Diplotaxis muralis, then Brassica erucastrum, and finally annotated to Coincya by I. Al-Shehbaz. Naczi & Thieret (1996) state that they have seen a 1994 collection, but we have not seen it.
Native of western Europe and northwestern Africa; in N.A. NY, PA, and WV to NC; also KY, MI. For an excellent discussion of its occurrences in N.A., see Naczi and Thieret (1996). | |
| Abundance | Very rare. Reportedly common in the Cane River valley (Yancey County) back in the 1950s. | |
| Habitat | Roadside, field. | |
| Phenology | Flowering and fruiting May-July (at least). | |
| Identification | Wallflower-cabbage has stems up to 3 feet tall, but usually less. Leaves are the best ID character. First, they are glaucous or glaucescent. The basal leaves are cut into pinnatisect lobes or segments; each segment has rather ragged or toothed margins. The lower stem leaves are similar but narrower, and up the stem they become progressively smaller and fewer-segmented such that the uppermost do not at all resemble the lowest. The flowers are terminal, yellow with maroon veins. The fruits are long, slender, and slightly curved. | |
| Taxonomic Comments | Synonyms include Sinapis recurvata and Brassica cheiranthos.
