Of conservation concern. Although Draba carnosula was reduced by Hitchcock to a variety of D. howellii, it differs significantly by having leafless flowering stems, 2–6-flowered racemes, and broadly winged seeds 3–4.5 mm in diam. Draba howellii almost always has 1–3-leaved stems, (5–)7–18(–25)-flowered racemes, and not winged, distally appendaged seeds 1–1.6 mm in diam. Draba carnosula is known only from a few collections from Mount Eddy in Trinity County and the north side of Mount Shasta in Siskiyou County.

Although originally treated as a variety of Draba lemmonii, D. incrassata is quite distinct both morphologically (R. A. Price and R. C. Rollins 1991) and chromosomally (M. D. Windham, unpubl.). The species is known from the Sweetwater Mountains in Mono County. (Discussion copyrighted by Flora of North America; reprinted with permission.) |
