Tipuana
thumb ''Tipuana tipu'', also known as ''Rosewood'' and ''Pride of Bolivia'', is a South American tree. It is the only member of the genus ''Tipuana''. It was recently assigned to the informal monophyletic ''Pterocarpus'' clade within the Dalbergieae.〔〔 ==Physical characteristics== Growing up to thirty metres in height and twenty metres wide, ''Tipuana tipu'' is well known for its use as a shade tree. The leaves of the tree are pinnately compound, 10" (25cm) long, and made up of leaflets 1 to 3 inches (2 to 7 centimetres) long. The flowers are bright yellow in color and bloom only briefly in the late summer. The fruit is a legume (pod) with the seed at one end, resembling a samara (the fruit of the Ash genus, ''Fraxinus''). It is a deciduous tree, shedding all of its leaves and large "helicopter" seed packets from January–May each year. It produces masses of seeds, most of which succeed in germinating, and it can withstand a very wide range of growing conditions, from –4°C to salty soils to drought.〔http://www.abc.net.au/gardening/stories/s1625878.htm〕 Timber is whitish in colour, strong and fibrous. Cut logs ooze resin which is blood-red. (see image)
