You are in dense, single, axillary coiling, which are supported by a sheet-like or reduced bract and showy, crescent Brakteolen. Her three sepals are free or fused together at their base. The three petals are free or united with the bases of the stamens and then form a short tube. Of the same six stamens all fertile. Their stamens are bearded and often swollen subterminal usually. The connectives are narrow. The ovary is dreifächrig. Each compartment contains two ovules.
