Petals usually small, mostly obovate. Stamens di- morphic, the epipetalous series smaller or in some species imperfect. Anthers obovoid to subulate; connective in the episepalous series prolonged below the thecae, bearing at base two rounded to linear, anterior appendages; that of the epipetalous stamens shorter or not prolonged, with two short or tuberculiform appendages. Ovary free, usually subglobose, 2- to 4-celled; style slender; stigma punctiform or truncate. Capsule 2- to 4-valved; seeds ovoid or oblong, more or less cochleate, minutely foveolate.
