Caesalpinia spinosa (Molina) Kuntze, commonly known as tara (Quechua), is a small leguminous tree or thorny shrub native to Peru. C. spinosa is cultivated as a source of tannins based on a galloylated quinic acid structure. This chemical structure has been confirmed also by LC-MS. It is also grown as an ornamental plant because of its large colorful flowers and pods.
