Characteristics

Trees to 40 m tall, dioecious, monoecious, andro-dioecious, or hermaphroditic. Petiole short or absent; leaf blade venation arcuately looped near margin. Inflorescences on young branches [rarely on trunks], rhipidial, solitary or in clusters; peduncle short [or long]; sympodial rachis internodes short [or long]. Flowers unisexual [or bisexual], pendent. Pedicel short or long, with submedian bracteoles. Sepals 3, valvate, free or basally connate, membranous. Petals 6, in 2 whorls, free, with each whorl valvate; outer petals generally shorter than inner petals, generally without basal claw, membranous; inner petals sometimes with adaxial glands, base generally clawed, apically connivent to form a mitriform dome. Male flowers: stamens [7-]46-56[-153], cuneate, extrorse, often with a ring of staminodes; connectives apically truncate. Female flowers: staminodes [0-]7-9[-20]; carpels [1-]7-14[-30], free; ovules [1-]5 or 6[-20] per carpel, in [1 or]2 series. Fruit apocarpous; monocarps shortly stipitate [or sessile], generally globose [or ellipsoid], mostly with longitudinal groove, [smooth or] rugose. Seeds smooth or rugose.

More

Trees or shrubs, unarmed, with simple hairs. Flowers unisexual, plants dioecious or (not usually in Australia)monoecious, axillary, cauline or ramal, solitary or many in fascicles or contracted cymes, mostly on slender pedicels, with basal and suprabasal bracts. Sepals valvate in bud, connate at base. Petals 6, valvate, in 2 strongly dissimilar series; outer petals spreading; inner petals coherent at anthesis by the margins of a rhombic or trowel-shaped blade above a narrow claw and forming a vaulted cap or dome. Male flowers: stamens c. 60 (in Australia), wedge-shaped; connective flat-topped, concealing anthers; pollen in tetrads; carpels absent. Female flowers: staminodes 6–18 (in Australia); carpels numerous; ovules few; stigma sessile, depressed-capitate with adaxial radial slit. Apocarps sessile (in Australia), indehiscent. Seeds 1-few, transverse, ellipsoidal with a medial groove.
