Abstract

Lesquerella (Brassicaceae) is united with the earlier-published Physaria following an unsuccessful attempt to conserve the more speciose Lesquerella. Molecular, morphological, distributional, and ecological data strongly support the union of the two genera. Ninety-one names in Lesquerella, including 75 at the specific rank, are transferred to Physaria. The new names P. nelsonii and P. reediana are proposed to avoid the creation of later homonyms in Physaria.
