Hypanthium almost flat. Bractlets, sepals and petals normally 5. Petals yellow, 

 oblong-cuneate, truncate or rarely slightly emarginate; sepals ovate, acuminate, about 

 equalling the petals; bractlets large, 3-5-toothed, generally exceeding both petals and 

 sepals. Stamens 20-25, rather short, closely surrounding the receptacle ; anthers opening, 

 by a longitudinal slit. Receptacle hemispheric, bearing numerous pistils, in fruit becom- 

 ing fleshy and red, but insipid in taste. Style filiform, attached to the middle of the 

 ovary, scarcely deciduous. Seeds ascending and amphitropous. 



The genus consists of two species, natives of India, but one is introduced into most 

 parts of the tropical and warmer temperate zones. The flowers are borne on long pedi- 

 cels from the axils of the leaves of the long flagelliform and often rooting branches.
