Capsule to 26 mm long, 8 mm wide, ellipsoid, opening by lenticellate valves. Seeds 4–7 per locule, winged at both ends.
NB Naming of plant confused. A large spreading tree. It loses its leaves. It grows 15-25 m high. The trunk is thick. The bark is dark grey and rough. It cracks into squares. The leaves are large and compound. They can be 90 cm long and have 10-14 pairs of narrow leaflets. These are 15 cm long. They have unequal sides. They taper to the tip. The edges are wavy. The veins are light green. The flowers are bell shaped. They are small and white. They occur in long sprays. The fruit are brown capsules. They split open in a star shape. The seeds have wings.
Tree up to 25 m. tall.. Leaflets 10–24, entire, lanceolate or lanceolate-elliptic, up to 15 × 5 cm., gradually tapering from near the base to the long, narrow, attenuate-acuminate apex; proximal lateral nerves on lower surface with minute deltate axillary pockets (domatia) with minute apical hairs.. Inflorescence up to 35 cm. long.. Capsule delicate, 1.5–2 cm. long, valves without conspicuous lenticels.. Fig. 13/7–12.
