It is known as algarrobo negro in Spanish, which means "black carob tree" (the Spanish settlers gave it that name, as they did with many other species of genus Prosopis, because of its similarity to the European carob tree). It is also variously called algarrobo dulce, algarrobo morado and algarrobo amarillo ("sweet", "purple" and "yellow" carob tree, respectively). The tree blossoms in September and October, and gives fruit from November to March. It grows together with the vinalillo tree (Prosopis vinalillo) and under the tops of the palm tree Copernicia alba. Like the other species of this genus, it tolerates arid climate, but can also survive in flooded ground for a long time. The heartwood is dark brown and very heavy, considered noble by local carpenters, also weather resistant, it presents streaks. UsageAlgarrobo negro wood is used in making furniture and barrels. High in tannin, it has been employed for leather tanning since the colonial era. Its fruit, called an algarroba, is a dehiscent-type pod, with a sweet, starchy paste inside, milled to make flour, and fermented to make an alcoholic beverage. Sources
