Acmispon denticulatus is a species of legume known by the common name riverbar bird's-foot trefoil. It is native to western North America from British Columbia to California to Utah, where it grows in moist spots in a number of habitat types. It is an annual herb growing erect or spreading to about 40 cm in maximum length. It is lined with leaves each made up of a few alternately arranged oval leaflets 1 to 2 cm long, sometimes slightly hairy in texture. The inflorescence is made up of one or two whitish to yellowish pealike flowers located in leaf axils. The fruit is a hairy legume pod up to about 1.5 cm long.

Acmispon maritimus, synonym Lotus salsuginosus, is a species of legume native to Arizona, California and northwestern Mexico. It is known by the common name coastal bird's-foot trefoil. It grows in many types of mountain, desert, and scrub habitat, not necessarily near the coast. It is an annual herb quite variable in morphology, from petite to bushy, hairless to roughly hairy, and prostrate to erect in form. The slender stems are lined with leaves each made up of pairs of leaflets variable in shape and size. The inflorescence is a small array of 1 to 4 yellow flowers, each up to a centimeter long or so. The elongated flower corolla emerges from a tubular calyx of sepals. The fruit is a legume pod up to 3 centimeters long. Laboratory studies have shown this species, which occurs in wildfire-prone habitat such as chaparral, to have an increased rate of seed germination after exposure to heat.
Pediomelum castoreum is a species of flowering plant in the legume family known by the common names beaver Indian breadroot and beaver dam breadroot. It is native to the deserts around the intersection of California, Nevada, and Arizona, where it grows in local habitat including disturbed areas. It is a perennial herb with no stem or a short stem that is mostly underground, leaving the plant at ground level. The compound leaves are each made up of five or six oval leaflets which may be over 4 centimeters long. The leaf is borne on a long petiole. The inflorescence is a raceme of several blue or purple pealike flowers each roughly a centimeter long. The fruit is a hairy oval legume pod tipped with a long, curved beak. It contains ridged gray seeds each about 6 millimeters long.
Senna armata is a species of flowering plant in the legume family known by the common names spiny senna and desert senna. It is native to the desert regions around the intersection of Nevada, Arizona, eastern California and northern Baja California, where it grows in sandy and rocky habitat, such as arroyos. It is a shrub growing up to a meter tall, its grooved, branching stems often narrowing to thorns at their tips. The spiny branches are coated in tubular hairs which help protect it from hot desert air. The spine-tipped leaves are each made up of two to four pairs of small leaflets. The leaves are ephemeral, dropping soon after emerging, leaving the shrub naked most of the time. Flowers occur singly or in small clusters in leaf axils. They are fragrant and showy, with five petals in shades of yellow to salmon pink, each measuring roughly a centimeter long. The fruit is a legume pod up to 4 centimeters long.
Astragalus holmgreniorum is a rare species of milkvetch known by the common names Holmgren milk-vetch and paradox milk-vetch.

Herbaceous annual or short-lived perennial growing up to 1 m high, it is native to the tropical and subtropical areas of Central and South America, and naturalized throughout the tropics. It is cultivated for forage or as a green manure or cover crop in rotation. As it quickly spreads on disturbed soils, it is considered an environmental weed in some areas.
