Shrubs and small trees, unarmed, terrestrial, without raphides in the tissues, sometimes with copious exudate covering vegetative and reproductive growth. Leaves opposite, petiolate, entire, with the higher-order venation not lineolate, without domatia, with well developed submarginal vein; stipules interpetiolar or shortly united around stem, triangular, keeled and cuspidate, erect and perhaps imbricated or valvate in bud, persistent after leaves fall. Inflorescences axillary at 1 node well below stem apex, spiciform with flowers in congested cymes or subcapitate groups, pedunculate, bracteate. Flowers bisexual, homostylous, apparently protandrous, perhaps fragrant and/or diurnal; hypanthium ellipsoid, flattened; calyx limb developed, deeply 5-lobed, without calycophylls; corolla at anthesis salverform, white to pale yellow or perhaps cream, somewhat small (0.6-0.8 cm), apparently glabrous inside, lobes 5, narrowly ligulate, in bud thinly imbricated with apparently two lobes internal two external, tightly reflexed and coiled at anthesis; stamens 5, inserted at base of corolla tube, filaments thickened and perhaps fused or coherent at base, anthers narrowly oblong, elongated, dorsifixed near base, dehiscent by linear slits, exserted, without appendages; ovary 2-locular, with ovules solitary and pendulous in each locule, stigma 1, slenderly cylindrical, with stigmatic lines twisted along sides, exserted. Fruit capsular, ellipsoid and flattened, loculidally and septicidally dehiscent from apex, septicidally fully deshicent into 2 valves 2, these partially loculicidal, rather small (ca. 5 mm long), chartaceous to woody, smooth, without lenticels, with calyx limb persistent; seeds 1 per locule, ellipsoid, compressed, small (ca. 2.5 mm), entire, densely verrucose to pilosulous.
