Aquilaria
Aquilaria is a genus of fifteen species of trees, called lign aloes or lign-aloes trees, in the family Thymelaeaceae, native to southeast Asia. They occur particularly in the rainforests of Indonesia, Thailand, Cambodia, Laos, Vietnam, Malaysia, Northeast India, Bangladesh, the Philippines, Borneo and New Guinea. The trees grow to 6–20 m tall. The leaves are alternate, 5–11 cm long and 2–4 cm broad, with a short acuminate apex and an entire margin. The flowers are yellowish-green, produced in an umbel; the fruit is a woody capsule 2.5–3 cm long.

The genus is best known, together with "Gyrinops", as the principal producer of the resin-suffused agarwood used in aromatic incense production, especially "Aquilaria malaccensis". The depletion of wild trees from indiscriminate cutting for agarwood has resulted in the trees being listed and protected as an endangered species. Projects are currently underway in some countries in southeast Asia to infect cultivated "Aquilaria" trees artificially to produce agarwood in a sustainable manner. In Indonesia, for example, there have been proposals to encourage the planting of gahara, as it is known locally, in eastern Indonesia, particularly in the province of Papua.
