Pterocarpus indicus (commonly known as Amboyna wood, Malay padauk, Papua New Guinea rosewood, Philippine mahogany, Andaman redwood, Burmese rosewood, narra[3] (from Tagalog[4]) and asana in the Philippines, angsana, or Pashu padauk) is a species of Pterocarpus of the Sweet Pea Family (Papilionaceae) native to southeastern Asia, northern Australasia, and the western Pacific Ocean islands, in Cambodia, southernmost China, East Timor, Indonesia, Malaysia,[5] Papua New Guinea, the Philippines, the Ryukyu Islands, the Solomon Islands, Thailand, and Vietnam.[6]
Pterocarpus indicus was one of two species (the other being Eysenhardtia polystachya) used as a source for the 16th- to 18th-century traditional diuretic known as lignum nephriticum.[7]
Many populations of Pterocarpus indicus are seriously threatened. It is extinct in Vietnam and possibly in Sri Lanka and Peninsular Malaysia.[1] It was declared the national tree of the Philippines in 1934 by Governor-General Frank Murphy of the Insular Government of the Philippine Islands through Proclamation No. 652.[8]
