Aquilaria is a genus of fifteen[1] species of trees in the Thymelaeaceae, native to southeast Asia. They occur particularly in the rain forests of Indonesia, Thailand, Cambodia, Laos, Vietnam, Malaysia, Northern India, 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, especially Aquilaria malaccensis.[1][2] The depletion of wild trees from indiscriminate cutting for agarwood has resulted in the trees being listed and protected as an endangered species.[1][2][3] Projects are currently underway in some countries in southeast Asia to infect cultivated Aquilaria trees artificially to produce agarwood in a sustainable manner.[3] In Indonesia, for example, there have been proposals to encourage the planting of gahara, as it is known as locally, in eastern Indonesia, particularly in the province of Papua[4]
