Climbing shrubs or woody lianas. Inflorescences 1- or few-flowered clusters; peduncle recurved, woody, persistent, forming a hook. Flowers bisexual, often fragrant. Torus flat or concave. Sepals 3, valvate, connate at base. Petals 6, in 2 whorls, pale yellowish, subequal, with each whorl valvate, base concave, apex connivent. Stamens many, outermost series sometimes forming staminodes; connectives apically dilated, apex truncate. Carpels 4 to many; ovules 2 per carpel, basal; stigmas ovoid, oblong, or clavate. Fruit apocarpous; monocarps fasciculate, sessile or shortly stipitate, ellipsoid-obovoid or globose, fleshy and berrylike. Seeds 1 or 2 per monocarp, without an aril.
Seeds held vertically, collateral; aril absent
Monocarps indehiscent, cylindric or ellipsoid, mostly not stipitate, 1–2-seeded, usually fleshy
Carpels mostly numerous, free, ovoid or ellipsoid, with 2 basal ovules; styles linear-oblong, shorter than or equalling the ovary
Stamens numerous (sometimes the outer ones staminodes), linear-oblong or cuneiform; filaments very short or absent; anther-cells extrorse; connective-appendages dilated, truncate
Petals 6, in 2 whorls of 3, both valvate, subequal, free, usually concave at the base and connivent over the stamens and carpels
Climbing or erect shrubs, rarely small trees with an indumentum of simple hairs or glabrous
Flowers hermaphrodite, pedicellate, solitary or in extra-axillary cymes, rarely terminal, mostly borne on very characteristic thickened hooked peduncles; buds ovoid; bracts and bracteoles small, mostly numerous, usually deciduous
Sepals 3, valvate, free or ± united at the base, equalling or smaller than the petals
Sepals 3, valvate, equal to the petals or shorter.
Petals 6, free, in two equal or unequal whorls, both valvate, usually thick, erect or spreading, flat or ± subulate, usually ± concave at the base and enclosing the reproductive parts.
Flowers bisexual, solitary or in condensed cymes, extra-axillary (rarely terminal), pedicellate, on usually hooked and flattened peduncles.
Bracts and bracteoles small, often caducous.
Shrubs or rarely small trees, usually climbing or scrambling, with simple hairs.
Seeds vertical, collateral; aril absent.
Ripe carpels indehiscent, succulent, cylindric or ellipsoid, 1–2-seeded.
Carpels few (6) to numerous, free; ovary ovoid or ellipsoid, with 2 basal ovules; style as long as the ovary or shorter, cylindric or ± flattened, oblique; stigma small.
