Small tree up to 5 m, with a broad irregular crown. Bark pale brown. Leaves impari- pinnate, 14–27 cm long, 10–27 cm wide; petiole 10–25 mm, petiole, rachis and petio- lules with few to numerous scales like those on the twigs. Petals 5. Staminal tube 1/2–1/3 the length of the corolla, cup- shaped with the apical margin slightly incurved and shallowly lobed; anthers 5, about 1/3 the length of the tube, broadly ovate, inserted just below the margin of the tube, protruding through the aperture and pointing towards the centre of the flower. Fruits up to 2 cm long and wide, orange–brown or orange-red, ellipsoid or sub– globose, densely covered with stellate scales like those on the twigs; inner surface of pericarp pink.

The Semang of the neighbourhood of Kuala Lipis pound the leaves in cold water and use the preparation for washing the body after child-birth . The arils are edible.

Notes

A rheophyte with leaflets which resemble the leaves of Salix viminalis L., hence the name of the synonym A. salicifolia. This species grows on river banks with the branches projecting horizontally over the water. It is most easily found by swimming near the bank until the strong citronella perfume emitted by the male flowers is detected. Several trees are usually found growing together, the female often bearing all reproductive stages from flower buds to ripe fruits. Aglaia yzermannii is found mainly in the Malay Peninsula where it seems to be restricted to the banks of relatively deep stretches of otherwise stony, fast flowing rivers. There is only one gathering known from Sumatra: the type specimen of A. yzer- mannii. The simple-leaved species, A. rivularis is found in Sabah and NE Kalimantan. The leaves of that species are almost identical to the leaflets of A. yzermannii, differing only in the presence of scales scattered on the lamina as well as on the midrib. Both spe- cies are rheophytes.
