'''''Prosopis pubescens''''' ('''Screwbean Mesquite'''), is a small [[tree]] or [[shrub]] found in the southwestern United States ([[Texas]], [[Arizona]], [[New Mexico]], [[California]]) and [[Mexico]]. It has light brown bark, usually short, straight spines (1-3 cm), twice-compound leaves, and numerous, small, yellowish flowers appearing in elongate spikes. It is found along streams and valleys in deserts particularly in damp or saline soil, and grows to about 7 meters (20 ft). The tree is also called "Tornillo" or simply "Screwbean". The name arises because the tightly twisted legumes very much resemble a turned screw. This morphology may have been an evolutionary defense agains seed predators such as bruchid beetles (bean weevils).<br />

Inflorescence of ''Prosopis pubescens''<br />
Like those of other mesquites, screwbean has nutritious pods that can be eaten. Mesquite meal is a traditional Native American food. Used as a staple food for centuries by desert dwellers, this high protein meal contains good quantities of calcium, magnesium, potassium, iron and zinc, and is rich in the amino acid lysine as well. Mesquite is high in fiber, moderate in sugar, and eight percent protein. It has a sweet, rich, molasses-like flavor with a hint of caramel which blends well into smoothies or other drinks, especially those made with cacao and maca.<br />
