Tomostima cuneifolia (Nuttall ex Torrey & A. Gray) Al-Shehbaz, M. Koch, & Jordon-Thaden. Common name: Wedgeleaf Draba. Phenology: Feb-Apr; Mar-May. Habitat: Calcareous barrens and glades, open blackland prairies, preferring rocky, bare soil, limestone outcrops, also waste areas around wool-combing mills, possibly other habitats. Distribution: IL south to LA, west to UT, NV, CA, and Mexico (BCN, BCS, CHH, COA, NLE, SON); scattered eastwards as apparently native disjuncts in OH, KY, TN, GA, AL, MS, and FL, and also as an occasional weed in NC and SC and perhaps other states. The species extends as a native at least as far east as c. GA (Houston County) (Echols 2007) and AL, where it occurs in prairies and on limestone outcrops (Diamond & Woods 2009).

Origin/Endemic status: Native

Taxonomy Comments: Taxa previously treated as additional varieties are now considered to be separate species.
