From east to west, it can be found from Illinois to Arizona. It is an orange or yellow small-flowered annual, with zygomorphic flowers consistent with the Zygophyllaceae, or creosote-bush family, to which it belongs. Leaves are compound and are 3–6 cm, with 4 pairs leaflets. The stem is pubescent and 30–60 cm. Flowers measure at 1 cm, while the ovoid fruit measures at 4 mm. The plant prefers dry soils and can be found in locations such as near roads and railroads.
