Scientific Name: Acacia auriculiformis
Tamil Name: Pencil maram
Description: Acacia auriculiformis is an evergreen tree that grows between to 15-30 m tall, with a trunk up to 12 m long and 50 cm in diameter. It has dense foliage with an open, spreading crown. Roots are shallow and spreading. Flowers are 8 cm long and in pairs, creamy yellow and sweet scented.
Note: The spreading, superficial and densely matted root system makes this wattle suitable for stabilizing eroded land. Shade or shelter: The dense, dark-green foliage, which remains throughout the dry season, makes it an excellent shade tree. Not widely used as fodder, but in India 1-year-old plantations are browsed by cattle. The wood is extensively used for paper pulp.
