Fruit a pendulous elongate woody septifragal capsule, cigar-shaped, fusiform, cylindric or claviform, opening by 5 valves from the apex or base or from the apex and base simultaneously; columella extending to the apex of the capsule, 5-angled or 5-ridged, softly woody, deeply indented with the imprints of seeds; seed-scars conspicuous or inconspicuous; seeds 3–8 per loculus, attached by the seed-end to the distal part of the columella, and winged towards the base of the capsule.
Ovary 5-locular, each loculus with 4–12 pendulous anatropous ovules in 2 rows; style short; style-head discoid with 5 radiating (?) stigmatic grooves on the upper surface, not completely blocking the entrance to the Staminal tube.
Disk (in our area) cushion-shaped, enveloping the base of the ovary and connected to the Staminal tube by 10 short ridges.
Staminal tube cup-shaped (in our area), margin entire with 10 anthers borne on very short filaments.
Calyx lobed in upper half or almost to base, lobes 5, aestivation open.
Petals 5, free, much longer than the calyx in bud, contorted.
Flowers (? always) monoecious, borne in panicles.
Leaves paripinnate, leaflets entire.
Trees, usually of large size.
