Calia is a genus of three or four species of shrubs and small trees in the subfamily Faboideae of the pea family, Fabaceae. The genus is native to southwestern North America from western Texas to New Mexico and Arizona in the United States, and south through Chihuahua, Coahuila and Nuevo León in northern Mexico. Members of the genus are commonly known as mescalbean, mescal bean or frijolito. One of the common names of C. secundiflora is Texas mountain laurel, although the name mountain laurel also refers to the very dissimilar and unrelated genus Kalmia (family Ericaceae) and the name laurel refers generally to plants in the unrelated order Laurales.
Although still commonly treated in the genus Sophora, recent genetic evidence has shown that the mescalbeans are only distantly related to the other species of Sophora.[2]

Description
Calia spp. grow to 1–11 m (3.3–36.1 ft) tall, with a trunk up to 20 cm (7.9 in) in diameter, often growing in dense thickets that grow from basal shoots. The leaves are evergreen, leathery, 6–15 cm (2.4–5.9 in) long, pinnate with 5-11 oval leaflets, 2–5 centimetres (0.79–1.97 in) long and 1–3 cm (0.39–1.18 in) broad. The flowers, produced in spring, are fragrant, purple, typical pea-flower in shape, borne in erect or spreading racemes 4–10 cm (1.6–3.9 in) long. The fruit is a hard, woody seedpod 2–15 cm (0.79–5.91 in) long, containing 1-6 oval bright red seeds 1–1.5 cm (0.39–0.59 in) long and 1 cm (0.39 in) in diameter.
All parts of the mescalbeans are very poisonous, containing the alkaloid cytisine (not mescaline, as suggested by the name). The seeds or other parts of the plant have been reported to have been used as a hallucinogen by some Native American people, but this is uncertain, due to confusion over names. The symptoms of cytisine poisoning are very unpleasant, including nausea and seizures; as little as one seed can be fatal.
