Schinopsis

Schinopsis is a genus of South American trees in the family Anacardiaceae. The species within this genus inhabit different regions of the Gran Chaco ecoregion including parts of northern Argentina, Bolivia, and Paraguay.

Their common name is quebracho, from Spanish quiebra-hacha ("axe-breaker") in recognition of the hardness of their wood, or more precisely quebracho colorado ("red quebracho"), to distinguish them from the "white quebracho" trees of the quite unrelated genus Aspidosperma.
