Petals 6, almost equal, imbricate, the upper one with its margins overlapped. Stamens 13–41, arranged round the base of the ovary, free or almost so; anthers basifixed, dehiscing by longitudinal slits; connective not glandular. Ovary sessile or nearly so, 2–5-ovuled, tapering upwards into a subulate style which is bent in its upper part and bears a minute capitate stigma.
