Gonzalo Alves (Astronium graveolens (syn. A. fraxinifolium)), also known as Jobillo or Tigerwood, is native to the Yucatán Peninsula in Mexico, Central America, and South America as far south as Bolivia. It grows to a height of 35 metres (100 ft). The trunk can have a diameter of up to 1 metre (39 in) and is straight and cylindrical. At the base it has buttresses which may be about 2 metres (7 ft) tall. When fresh, the heartwood of Astronium graveolens is reddish-brown or orange-brown with variable width stripes of medium to dark brown. The timber becomes darker after exposure to the air and the stripes become nearly black. The sapwood is up to 10 centimetres (4 in) thick and is whitish or dull grey. The timber is fine-grained, dense and durable, and resistant to rot.
