 bright scarlet, with a leathery top-shaped calyx divided at the top into 5 or 7 valvate 

 lobes; petals as many as the divisions of the calyx and alternating with them, or 

 in double-flowered varieties numerous; stamens many, inserted around the mouth

 globose, bearing the persistent calyx, many-celled, containing very many angular 

 seeds, with coriaceous testa and watery outer coat containing a pelucid red juice of a
