''Heritage Trees of Penang''. Penang: Areca Books. ISBN 978-967-57190-6-6〕 Papua New Guinea, the Philippines, the Ryukyu Islands, the Solomon Islands, Thailand, and Vietnam.〔International Legume Database & Information Service: (''Pterocarpus indicus'' )〕 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. ==Description== 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. 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.〔Danida Seed Leaflet: (''Pterocarpus indicus'' (pdf file) )〕〔Purdue University New Crops: (''Pterocarpus indicus'' )〕 Most ''Pterocarpus'' species prefer seasonal weather but ''P. indicus'' prefer rainforests. 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. 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Pterocarpus indicus」の詳細全文を読む スポンサード リンク
