Pterocarpus indicus (amboine, Pashu padauk, Malay paduak, New Guinea rosewood, Philippine mahogany or, ambiguously, "narra" which can refer to several Pterocarpus species) is a species of Pterocarpus native to southeastern Asia, northern Australasia, and the western Pacific Ocean islands, in Cambodia, southernmost China, East Timor, Indonesia, Malaysia, Papua New Guinea, the Philippines, the Ryukyu Islands, the Solomon Islands, Thailand, and Vietnam. Other names include Narra (Philippines), Sonokembang (Indonesia), Angsana or Sena (Indonesia, Malaysia and Singapore), Tnug (Cambodia).
Pterocarpus indicus was one of the two species (the other being Eysenhardtia polystacha) used as a source for the 16th to 18th-century traditional diuretic known as lignum nephriticum.
Many populations of Pterocarpus indicus are seriously threatened. It is extinct in Vietnam and possibly in Sri Lanka and the Peninsular Malaysia.
It is the national tree of the Philippines.
