Schinopsis lorentzii is a hardwood tree known as red quebracho, native of the Paraguayan subtropical area, which forms forests in Gran Chaco region of Argentina, in Paraguay, and Bolivia. Some of its common names are coronillo, quebracho Cornillo (Brazil), quebracho chaqueño, quebracho colorado santiagueño, quebracho macho, and quebracho bolí. The qualification colorado ("red") differentiates it from other species of common quebracho tree, the Aspidosperma quebracho-blanco (quebracho blanco, "white quebracho", family Apocynaceae). The indication santiagueño (from Santiago del Estero) is made to distinguish it from quebracho colorado chaqueño, a closely related species (Schinopsis balansae).
