Tipuana tipu, also known as tipa is a South American tree. It is the only member of the genus Tipuana. Growing up to 30 metres (98 ft) in height and 20 metres (66 ft) wide, Tipuana tipu is well known for its use as a shade tree. The leaves of the tree are pinnately compound, 10 inches (25 cm) long; the pinnules typically are 1 to 3 inches (2 to 7 cm) long, and are variably paripinnate or imparipinnate on the same tree. The flowers are bright yellow in color and bloom only briefly in the late summer. The fruit is a hard, pod with the seed at one end, resembling a samara (the fruit of the Ash genus, Fraxinus)

The leaves are bipinnate in most species, pinnate or simple in a few species.

Schinopsis balansae is a hardwood tree known as willow-leaf red quebracho which forms forests in the subtropical Gran Chaco ecoregion of north-eastern Argentina, and Paraguay. This tree can reach 24 metres in height and more than one metre in diameter. Its trunk is straight, with a brownish-gray bark. Its wood is extremely heavy (relative density = 1.2). Its main use is the extraction of quebracho extract, which is 63% pure tannin.The tree was declared Argentina's "National Forest Tree" in 1956.
