Abstract

Three new species of Physaria (Nuttall) A. Gray from the western United States are described and illustrated: P. eriocarpa Grady & O'Kane, P. pachyphylla O'Kane & Grady, and P. pycnantha Grady & O'Kane. Physaria curvipes (A. Nelson) Grady & O'Kane and P. spatulata (Rydberg) Grady & O'Kane are proposed as new combinations in the genus and are provided with updated descriptions. Taxonomic changes are the product of a molecular study of these species and others formerly allied with P. reediana O'Kane & Al-Shehbaz ( = Lesquerella alpina (Nuttall) Watson). A key is provided that includes the species described here as well as other central Rocky Mountain species traditionally affiliated with P. reediana.
