Discussion
Chlorocrambe hastata is rare and known from only a few counties in Idaho (Washington County), Oregon (Baker and Wallowa counties), and Utah (Cache, Salt Lake, Utah, and Wasatch counties). It is easily distinguished from the other North American species of Brassicaceae by having yellowish green, reflexed flowers in lax racemes, hastate and petiolate cauline leaves, and fruits borne on distinct gynophores.
Selected References
None.
