Caesalpinia mexicana is a species of flowering plant in the pea family, Fabaceae. Common names include Mexican holdback,[2] Mexican caesalpinia, and tabachín del monte.[3] It is native to the extreme lower Rio Grande Valley of Texas[4] in the United States and south to central Mexico.[5] Its range in Mexico includes the northeast and further south along the Gulf coast as well as the Pacific coast in Nayarit, Jalisco, Colima, and a small portion of Sinaloa.[6]

Description

Mexican caesalpinia is a small evergreen tree or large shrub, reaching a height of 3–4.6 m (9.8–15.1 ft) and a spread of 1.8–3 m (5.9–9.8 ft). Leaves are bipinnately-compound and dark green.[7] Each leaf has five to nine pinnae 4–9 cm (1.6–3.5 in) in length.[8] Pinnae are composed of four to five leaflets[7] that are 1–2.5 cm (0.39–0.98 in) long and 0.7–1.3 cm (0.28–0.51 in) wide.[8] Yellow, slightly fragrant flowers are produced on 7.6–15.2 cm (3.0–6.0 in) terminal spikes[7] of 10 to 30.[3] Blooming takes place from February to July, often continuing to October. The fruit is a dehiscent tan or yellow seedpod 5.1–7.6 cm (2.0–3.0 in) in length.[7]

Uses

Mexican caesalpinia is cultivated as an ornamental because of its showy flowers, lush,[3] fine-textured foliage, and drought tolerance.[9]

Ecology

Caesalpinia mexicana is the host plant for the caterpillars of the curve-winged metalmark (Emesis emesia).[10]
