Description Flowers 4- to 5-merous. Hypanthium urceolate or subglobose to campanulate or nearly tubular. Calyx- tube often conspicuously prolonged; sepals minute or obsolete; exterior teeth varying from minute tubercles to long subulate appendages often simulating a sepal. Petals small, lanceolate to ovate, acute or acuminate, usually with an infra-apical exterior tooth. Stamens isomorphic, erect; filaments slender; anthers linear to oblong; connective simple or very briefly prolonged below the thecae and in a few species continued below the filament into a minute dorsal appendage. Ovary inferior, 3- to 5-celled; style filiform; stigma punctiform or capitellate. Fruit a many-seeded berry, often terminated by the enlarged calyx- tube. Small trees or shrubs with white flowers in fascicles or paniculiform cymes in the axils of existing leaves.
