Corydalis halei (Small) Fernald & Schubert. Southern Corydalis. Phen: Feb-May; Apr-Jun. Hab: Sandy roadsides and disturbed areas. Dist: E. NC south to FL, west to TX, and inland north to IL, MO, and OK.

Origin/Endemic status: Native

Taxonomy Comments: Fernald (1950) and Small (1933) recognized this taxon as a species distinct from C. micrantha; Ownbey reduced it to a subspecies, citing inadequate morphological differences and some alleged intermediates in OK and MO. The two taxa appear readily separable on morphological, ecological, and geographical grounds; species status seems warranted.
