Family: Fabaceae
Acrocarpus fraxinifolius (pink-cedar, shingle tree) is a deciduous tree native to tropical and temperate Asia. It is used as a shade tree in coffee plantations in India. The timber has many woodworking uses, such as furniture, cabinets, general construction, tea crates, and much more. The species also provides food for the endangered lion-tailed macaque when other fruit is scarce. It is reported to be naturalized in East Africa and reported to be an environmental weed there, several hundred trees were planted in Oʻahu forest reserves in 1931, but it has not been reported to be naturalized to date. This tree forms dense stands, shading out native species. It grows extremely rapidly, from 4.2 to 9.8 feet a year and creates numerous winged seeds that can travel far distances. It also has a smothering habit and will climb and strangle other trees.
