Inflorescences usually axillary and occurring in several leaf axils along the branches or branchlets, sometimes also terminal or on the top of a reduced or very short branchlet with bract-like reduced leaves, 1-5-flowered; peduncle very short to 1.5 cm, appressed-pu-berulous. Flowers 10-13 mm long, yellowish, or cream (fide CLEMENS 20980), subsessile. Floral tube scattered-puberulous outside, glabrescent. Calyx lobes ovate-oblong, 2-3 mm long. Stamens with c. 0.5 mm space between the two whorls, those of the upper series sessile or sometimes some of them shortly filamentous, those of the lower series always shortly filamentous; anthers linear, 1-1½ mm long, acute or slightly apiculate.

Uses. According to BOORSMA ( BOORSMA Bull. Dep. Agric. I.N. n. 1 1907 19 ) it provides a scented wood which is used only occasionally. The wood is harder than that of Aquilaria and scentless, but when burned it gives forth a fragrance similar to that of Aloe-wood. In Banka the bark is used for making ropes.
