Correction: Tara, (Caesalpinia spinosa) Park Ceret S Paulo Brazil. A peru native tree.

Caesalpinia spinosa (Molina) Kuntze, commonly known as tara, 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. It is also grown as an ornamental plant because of its large colorful flowers and pods.

Caesalpinia is a genus of flowering plants in the legume family, Fabaceae. Membership within the genus is controversial, with different publications including anywhere from 70 to 165 species, depending largely on the inclusion or exclusion of species alternately listed under genera such as Hoffmannseggia. It contains tropical or subtropical woody plants. The generic name honors the botanist, physician and philosopher Andrea Cesalpino (1519-1603).

The name Caesalpinaceae at family level, or Caesalpinioideae at the level of subfamily, is based on this generic name.

The Fabaceae or Leguminosae, commonly known as the legume, pea, or bean family, is a large and economically important family of flowering plants. The group is the third largest land plant family, behind only the Orchidaceae and Asteraceae, with 730 genera and over 19,400 species. The largest genera are Astragalus (over 2,400 species), Acacia (over 950 species), Indigofera (around 700 species), Crotalaria (around 700 species), and Mimosa (around 500 species).

Plants of this family are found throughout the world, growing in many different environments and climates. A number are important agricultural plants, including: Glycine max (soybean), Phaseolus (beans), Pisum sativum (pea), Cicer arietinum (chickpeas), Medicago sativa (alfalfa), Arachis hypogaea (peanut), Ceratonia siliqua (carob), and Glycyrrhiza glabra (licorice), which are among the best known members of Fabaceae.

A number of species are also weedy pests in different parts of the world, including: Cytisus scoparius (broom), Ulex europaeus (gorse), Pueraria lobata (kudzu), and a number of Lupinus species.
