Acacia constricta Acacia constricta
Vachellia constricta, also known commonly as the whitethorn acacia, is a shrub native to Mexico and the Southwestern United States, with a disjunct eastern population in Virginia and Maryland.[2][3]
In the Southwest V. constricta grows in the southern half of Arizona, extending into New Mexico and West Texas. It grows in Mexico as far south as Oaxaca, with small disjunct populations in Baja California and in the Magdalena Plain of Baja California Sur.
In the Sonoran Desert, Vachellia constricta grows in arroyos and washes, where it blooms in late spring (April–May), with a second round of blooms in July–October. Blooming requires a minimum amount of rain, followed by a period of warmth.
Vachellia constricta typically grows to 2 metres (6.6 ft) in height, occasionally reaching 6 metres (20 ft). Its stems range from a light gray to a mahogany color, with pairs of straight white spines anywhere from 0.5 to 2 cm long.
The small leaves are even-pinnate, usually 2.5–4 cm in length, with each of the 3–9 pairs of pinnae made of 4–16 pairs of leaflets, which are about 3.5 mm long and 1 mm wide. The flowers occur in small yellow balls about 1 cm in diameter. The flowers offer no nectar and little pollen, and so tend to have few visitors. Extrafloral nectaries grow along the main stem of the compound leaves and attract ants to the trees. The seed pods are relatively long and thin, up to 12 cm long but only 3–6 mm wide.
The leaves may drop in response to either dryness or cold.
Vachellia constricta is cultivated by specialty plant nurseries as an ornamental plant. It is used in native plant desert habitat gardens. It can be trained as a small tree or grown as a barrier hedges.

El chaparro prieto, vara prieta, gigantillo, hizachilla o largoncillo (Acacia constricta)[1] [2] es un árbol o arbusto de la familia de las leguminosas. Habita desde el suroeste de Estados Unidos hasta el centro de México (su límite sur es el estado de Oaxaca)[3] en matorrales secos (matorral tamaulipeco), pastizales gipsófilos y halófitos y bosques de encinos alterados, desde los 500 hasta los 2800 m s. n. m. (metros sobre el nivel del mar).[4]
Alcanza hasta 6 m (metros) de alto. Tiene hojas de 2 a 5 cm (centímetros) de largo, con 3 a 7 pares de pinas de hasta 2 cm de largo y hasta 10 pares de folíolos por pina. Los folíolos son elíptico-oblongos, glabros o con algunos pelos esparcidos. La inflorescencia es de 1 cm de diámetro. Las flores son fragantes y producen néctar. El fruto es una vaina rojiza, recta o ligeramente curva, constreñido entre las semillas, dehiscente, glabro y con algunos puntos glandulares, de hasta 10 cm de largo, y 2-5 mm (milímetros) de grueso. Número cromosomático reportado: 2n=52.
Se reconocen dos variedades de esta especie: Acacia costricta Benth. var. costricta y A. constricta var. vernicosa (Standl.) L.D. Benson.[4]
