Calyx of many sepals, united below into a fleshy inversely .conical cup (with 

 some leaf-like bractlets growing from it) ; the lobes lanceolate, mostly colored 

 like the petals, which are similar, in many rows, thickish, inserted on the top 

 of the closed calyx-tube. Stamens numerous, inserted just within the petals, 

 short ; some of the inner ones sterile (destitute of anthers). Pistils several or 

 many, inclosed in the calyx-tube, inserted on its base and inner face. Aromatic
