Shrubs or small trees, unarmed, rather succulent, sometimes with stilt roots; young growth usually mucilaginous or resinous. Raphides presumably absent. Leaves opposite, decussate, without domatia, notably leathery, with petioles articulate; stipules persistent, united around stem, rounded to truncate, entire, enclosing well-developed colleters. Inflorescence axillary, congested-cymose with axes often articulate and regularly dichotomous, pedunculate, bracteate with bracts small and fused in pairs, apparently caducous. Flowers sessile or pedicellate, bisexual, monomorphic. Calyx limb cupuliform, subtruncate or (4 or)5-denticulate. Corolla white or pink, salverform with tube somewhat expanded in throat, pubescent inside; lobes (4 or)5, convolute in bud. Stamens (4 or)5, inserted in corolla just below throat, partially to fully exserted; filaments short; anthers dorsifixed, bifid at base. Ovary 2-celled, ovules 2 in each cell, axile and attached in middle of septum with 1 erect and 1 pendulous; stigmas 2, exserted. Fruit drupaceous (or indehiscent depending on interpretation), ellipsoid-oblong to ellipsoid, often weakly curved, fleshy becoming corky, (6-)8-ridged or-winged, with calyx limb persistent; pyrene 1, 2-celled, with 2 seeds in each cell, ellipsoid and longitudinally ridged or winged; seeds medium-sized, subcylindrical; testa membranous; endosperm reduced; cotyledons oblong; radicle long.
