Flora of Virginia Name/Status
Acmispon helleri (Britt.) A.A. Heller
Closely related to, and sometimes treated as a var. of Acmispon americanus (Nutt.) Rydb. (= Lotus unifoliatus [Hook.] Benth.) of midwestern prairies. If considered (as here) a separate species, A. helleri is a narrow Piedmont endemic, ranging from sc. VA to ne. GA.
Road banks, clearings, and old fields, usually in dry, barren, clay soils. This se. Piedmont endemic may have originally been associated with fire-influenced oak woodlands and prairies. Rare, s. Piedmont (Bedford, Charlotte, Halifax, and Pittsylvania counties).
