Schinopsis lorentzii is a hardwood tree, 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 colorado santiagueno, quebracho macho, and quebracho boli. The qualification colorado ("red") differentiates it from other species of common quebracho tree, the Aspidosperma quebracho-blanco . The indication santiagueno (from Santiago del Estero) is made to distinguish it from quebracho colorado chaqueno, a closely related species (Schinopsis balansae).
This tree is commercially very important due to its extremely hard and durable wood, and because of its tannin. The tanning industry has been exploiting quebracho forests for more than 100 years.
