var. brevialatus (Ottley) Brouillet
Short-winged deerweed differs from variant scoparius mainly in that the keel is longer than the wings, and the entire flower is a bit smaller. This is the variant that is more commonly found on desert slopes, flats and washes mostly to about 4000'. These pictures were taken in Mission Creek Preserve in the northern Colorado Desert. It may be found blooming from March to August.
