Useful Bertam Palm
A most unusual, densely clustering, large palm that grows to about 20 m (67 ft.) tall. Native to the island of Borneo, it forms extensive thickets in tropical rain or heath forest. The suckering trunks are supported by a large number of strong stilt roots. The large crown bears numerous upright to spreading leaves with spiny midribs and elegantly arching leaflets. Each trunk in a cluster flowers only once with a large terminal inflorescence. The fruits are large and covered in small, fringed scales. The seeds are protected by a very hard shell. All parts of the palm are used extensively by local people for construction purposes and thatching. The starchy pith of the trunk is extracted as sago.
