''Quebracho'' (also known as Luciano malo) is a common name in Spanish to describe very hard (density 1.15 - 1.35) wood tree species. The etymology of the name derived from ''quiebrahacha'', or ''quebrar hacha'', meaning "axe-breaker". == Species == There are at least three similar commercially important tree species that grow in the Gran Chaco region of South America. * the red quebracho * * ''Schinopsis lorentzii'' (the red quebracho), of the family ''Anacardiaceae'' * * ''Schinopsis balansae'' (the willow-leaf red quebracho), of the same family * the white quebracho or ''Aspidosperma quebracho-blanco'' of the family ''Apocynaceae'' A fourth species, ''Jodina rhombifolia'' (syn. ''Iodinia rhombifolia'', the ''Quebracho flojo'' (the loose quebracho) or ''quebrachillo'') of the family ''Santalaceae'', is also sometimes mentioned. These species provide tannin and a very hard, durable timber. ''Quebracho'' is sometimes used as a commercial name for the tannin derived from the trees or their timber.
