Prosopis glandulosa


Prosopis glandulosa, commonly known as honey mesquite, is a species of small to medium-sized, thorny shrub or tree in the legume family.

Distribution

The plant is primarily native to the Southwestern United States and Northern Mexico. Its range extends on the northeast through Texas and into southern Kansas, and west to southern California.
It can be part of the Mesquite Bosque plant association community in the Sonoran Desert ecoregion of California and Arizona, and Sonora state.

Description

Prosopis glandulosa has rounded big and floppy, drooping branches with feathery foliage and straight, paired spines on twigs. This tree normally reaches, but can grow as tall as. It is considered to have a medium growth rate.
It flowers from March to November, with pale, yellow, elongated spikes and bears straight, yellow seedpods. The seeds are eaten by a variety of animals, such as scaled quail. Other animals, including deer, collared peccaries, coyotes, and jackrabbits, feed on both pods and vegetation.

Varieties

Prosopis glandulosa has been intentionally introduced into at least a half-dozen countries, including Australia, Botswana, Namibia and South Africa. The IUCN considers it as one of the world's 100 worst invasive species outside its native habitat range.
The seeds are disseminated by livestock that graze on the sweet pods, and the shrubs can invade grasslands, with cattlemen regarding mesquites as range weeds to be eradicated. Due to latent buds underground, only coppicing them makes permanent removal difficult. A single-trunked tree that is cut down will soon be replaced by a multi-trunked version.

Uses

Prosopis glandulosa shrubs and trees provide shelter and nest building material for wildlife, and produce seed pods in abundance containing beans that are a seasonal food for diverse birds and small mammal species. As the common name indicates, honey mesquite is a honey plant that supports native pollinator species of bees and other insects, and cultivated honey bees. It is a larval host for the long-tailed skipper and Reakirt's blue butterflies.
Mesquite flour contains abundant protein and carbohydrates, and can be used in recipes as a substitute for wheat flour.
In Namibia, although an invasive species, it has qualities that have made it useful for humans, including: growing extremely rapidly there, having very dense shade, abundantly producing seed pods, and a readily available firewood.

Indigenous peoples

The indigenous peoples of California and southwestern North America used parts of Prosopis glandulosa as a medicinal plant, food source, building and tools material, and fuel.
The Cahuilla ate the blossoms and pods, which were ground into meal for cake.
The thorns of the plant were used as tattoo needles, and the ashes for tattoos, by the Cahuilla and Serrano Indians of Southern California. Its dense and durable wood is prized for making tools and arrow points, and for the unique flavor it lends to foods cooked over it. The deep taproots, often larger than the trunks, are dug up for firewood.
This species of mesquite, known as haas by the Seri people of northwestern Mexico, was very important for food and nonfood uses. The Seris had specific names for various stages of the growth of the mesquite pod. Historically, it was a very important wild food plant because it fruits even during drought years.
