Quebracho, the name applied to various hard woods containing tannin which are used for tanning and dyeing in South America. Quebracho blanco, containing 14 to 16 per cent., is Aspidosperma Quebracho, and is exported to France. Quebracho rubio, Loxopterygium Lorentzii, from the River Plate, is too hard for easy use. Quebracho flojo is Iodina rhombifolia, and tipa is Machaerium fertile. We only import a few hundred tons.
