Erysimum arenicola S. Watson[FNA7, HC, HC2]
sand-dwelling wallflower

Publication: Proc. Amer. Acad. Arts. 26: 124. 1891.

Origin: Native

selected vouchers: WTU

Notes: FNA7: "Erysimum arenicola is distributed at the higher elevations of northern Oregon northward into the Olympic and Cascade mountains in Washington and Vancouver Island.

Both G. B. Rossbach (1958) and R. C. Rollins (1993) recognized Erysimum arenicola as a distinct species. It is closely related to E. perenne and both can be easily distinguished from E. capitatum, with which they hybridize where their ranges meet, by the strongly torulose (versus not torulose) fruits and the longer styles 1.5-5.5 versus 0.2-2.5(-3) mm."
