Lesquerella vicina (Brassicaceae) is proposed for a perennial with white flowers found near Montrose, Colorado. It is most closely related to the yellow-flowered L. rectipes, differing additionally by having broader basal leaves. In the Montrose area it grows on Mancos Shale from 6000 to 7200 feet at the ecotone between pinyon-juniper woodland and salt desert scrub.,At the lower elevation the plants have a more ephemeral growth form, but at the higher elevations the plants are longer-lived perennials with well-developed caudices.
