Pterocarpus indicus (red sandalwood) | CABI Compendium (cabidigitallibrary.org)
Pterocarpus indicus (commonly known as Amboyna wood, Malay padauk, Papua New Guinea rosewood, Philippine mahogany, Andaman redwood, Burmese rosewood, narra (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, Papua New Guinea, the Philippines, the Ryukyu Islands, the Solomon Islands, Thailand, and Vietnam.
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.
Many populations of Pterocarpus indicus are seriously threatened. It is extinct in Vietnam and possibly in Sri Lanka and Peninsular Malaysia. 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.

It is a large deciduous tree growing to 30–40 m tall, with a trunk up to 2 m diameter. The leaves are 12–22 cm long, pinnate, with 5–11 leaflets, the girth is 12–34 m wide. Most Pterocarpus species prefer seasonal weather but P. indicus prefer rainforests.
The flowers are produced in panicles 6–13 cm long containing a few to numerous flowers; flowering is from February to May in the Philippines, Borneo and the Malay peninsula. They are slightly fragrant and have yellow or orange-yellow petals. The fruit is a semiorbicular pod 2–3 cm diameter, surrounded by a flat 4–6 cm diameter membranaceous wing (wing-like structure) which aids dispersal by the wind. It contains one or two seeds, and does not split open at maturity; it ripens within 4–6 years, and becomes purple when dry. The central part of the pod can be smooth (f. indica), bristly (f. echinatus (Pers.) Rojo) or intermediate.[9][10]
Note: Pterocarpus macrocarpus, a similar species native to Burma, is referred to as "Rosewood" throughout South East Asia. P. macrocarpus is usually harder than P. indicus. When in burl form both are referred to as Amboyna Burl.
