Rattan belongs to the class of climbing palms. Some rattan varieties grow as thickets while others climb on tall trees, and they are distinguished by the smoothness of their skin and diameter of the poles. Three rattan varieties are commonly used in the manufacture of furniture and furnishings, trays, baskets, and other handicrafts, as well as excellent twine. These are Arurog (Calamus javensis), Palasan (Calamus maximus), and Sika (Calamus spinifolius).
