Flowers 1–1.75 mm long, 1–2 mm wide, pedicels 0.5–1.5 mm; the pedicel and calyx densely covered with peltate scales which have a fimbriate margin. Staminal tube 0.5–1.2 mm long, 0.8–1.5 mm wide, cup-shaped or obovoid, anthers 5, inserted just inside the rim of tube and pointing to- wards the centre of the flower.

Aglaia speciosa usually has 7–11 leaflets, whereas A. korthalsii usually has 5 leaFl. ets. In Borneo some, but not all, leaves on a specimen may have fewer than 7 leaflets, but then the dense indumentum of small peltate scales, which have a distinctly dark centre and clearly defined pale margin which is closely adherent to the leaflet sur- face, distinguish it from A. korthalsii. The 12–15 pairs of veins together with the indu- mentum of peltate scales only, distinguish A. speciosa from A. odoratissima, which has 5–9(–11) pairs of veins and a mixture of peltate and stellate scales. The stigma is often longer and narrower than in A. korthalsii. The fruit is similar to, but larger than that of A. odoratissima, and contains one or two seeds.
