Descurainia pinnata ssp. brachycarpa is an annual herb that is native to California.
[swbiodiversity.org] Identification Details: Except for having numerous instead of one or few stems from the base, Descurainia ramosissima is indistinguishable from D. pinnata subsp. brachycarpa in every aspect of indumentum, leaf morphology, flower size, seed size and arrangement, and fruit size and orientation. Plants of the type collections (Rollins et al. 8349, holotype GH, isotypes GH, MO) are infected with white rust, a fungus disease rarely encountered elsewhere in North American Descurainia. It is not known if this unusual branching is inherited or disease-related, but it should not be used as the main reason for recognizing a species separate from D. brachycarpa.
