New species and combinations in Physaria (Brassicaceae) from Western North America
Brassicaceae, Canada, Lesquerella, Physaria, United States
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.
