'''''Gyrinops''''' is a genus of nine species of trees, called '''lign aloes''' or '''lign-aloes trees''', in the family Thymelaeaceae.<ref>[http://eol.org/pages/5469849/overview EOL - ''Gyrinops'']</ref> They are native to Southeast Asia, the Indian subcontinent, and New Guinea.<ref name = powo/>

The genus ''Gyrinops'' is closely related to ''Aquilaria'' and in the past all species were considered to belong to ''Aquilaria.''<ref>Blanchette, Robert A.

==Agarwood production== Together with ''Aquilaria'' the genus is best known as the principal producer of the resin-suffused agarwood.<ref name="Barden">Barden, Angela (2000) ''Heart of the Matter: Agarwood Use and Trade and CITES Implementation for Aquilaria malaccensis'' TRAFFIC International, Cambridge, {{ISBN|1-85850-177-6}}</ref><ref name="Ng">Ng, L.T., Chang Y.S. and Kadir, A.A.

(1995) "Agarwood harvesting in Vietnam" ''TRAFFIC Bulletin'' 15:96</ref><ref name="Ng"/><ref name="Barden"/>

Projects are currently underway in some countries in southeast Asia to infect cultivated trees artificially to produce agarwood in a sustainable manner.<ref name="Broad"/> 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.<ref>Theresia Sufa, '[http://www.thejakartapost.com/news/2010/02/02/gaharu-indonesia039s-endangered-fragrant-wood.html Gaharu: Indonesia's endangered fragrant wood'], ''The Jakarta Post'', 2 February 2010.</ref>
