Johnstone river-teak

Intsia bijuga, known as kwila, merbau, ipil or Johnstone River teak, is a large hardwood tree in the family Fabaceae, native to coastal areas from East Africa through India and Southeast Asia to northern Australia and the western Pacific. It commonly reaches 20 to 40 metres in height, with a buttressed trunk and a spreading crown. The leaves are pinnately compound, usually with two pairs of large, glossy, asymmetric leaflets (the epithet "bijuga" meaning two-paired). Showy flowers with a single conspicuous white to pink petal are borne in dense clusters, attractive to pollinators. The fruit is a thick, woody, flattened legume pod containing large hard seeds. The tree yields a heavy, durable, dark reddish-brown timber that is highly prized for flooring, furniture and boatbuilding, which has led to overexploitation in parts of its range. It often grows on beaches, tidal flats and coastal forest.
