Brassicaceae, Lesquerella, Paysonia, Physaria, Southeastern United States
The annual, auriculate-leaved species of Lesquerella (Brassicaceae) of the southeastern United States are transferred to the new genus Paysonia. The new combinations Paysonia auriculata, P. densipila, P. grandiflora, P. lasiocarpa, P. lasiocarpa subsp. berlandieri, P. lasiocarpa subsp. heterochroma, P. lescurii, P. lyrata, P. perforata, and P. stonensis are proposed. The distinguishing characters between the combined taxon Lesquerella-Physaria are discussed. A detailed description of the genus and a key to the species are provided.
