    Small trees or shrubs. Flowers small, axillary, sometimes produced on the older, leafless branches; pedicels bracteolate. Sepals thin, valvate in bud, free or sometimes connate at first and irregularly splitting, often deciduous. Petals valvate, all rather alike, but the inner mostly a little smaller and thicker, all, or only the inner, keeled on the inner surface above the middle. Stamens several, the innermost often sterile; connective of the fertile stamens not forming a disk above the pollen sacs, elongated into a ligule, sometimes very short. Carpels several; ovules 2, erect, produced from the basal part of ovary cavity. Monocarps free, dry, stipitate, club- shaped, opening along the inner sides. Seeds 2, very smooth and lustrous, appressed against each other and therefore plane on one side side and convex on the other.
