Peteria thompsoniae is a species of flowering plant in the legume family known by the common names spine-noded milkvetch and Thompson's peteria. It is native to the western United States, where it grows in salt desert shrublands in soils of volcanic ash origin,[1] and in alluvial fans. It is a spiny perennial herb growing from a taproot and rhizome system, its stem growing 20 to 60 centimeters tall. The leaves are made up of several pairs of oval leaflets. The inflorescence, a spikelike raceme at the top of the stem, produces white or pinkish pealike flowers up to 2.5 centimeters long, its base encapsulated in a tubular calyx of glandular sepals. The fruit is a leathery, slightly inflated legume pod up to 6 centimeters long.
