« Calyx 5-parted to near the base, the lobes foliaceous. 



8. ATROPA. Calyx with ovate divisions, in fruit enlarging and spreading under 



the globose purple berry. Corolla between bell-shaped and funnel-form, witli 

 B triangulai^ovate lobes. Stamens and style somewhat declined, slender. 



9. PETUNIA. Calyx with narrow somewhat spatulate lobes much longer than 



the tube. Corolla funnel-form or somewhat salvei^shaped, the 5-lobed border

 2-celled, 2-valved. 



« * * Calyx liibidar, prismatic, or bell-shaped, 



.*- Covering the dry pod or nearly so .' corolla salver-shaped or fiinnel-form, the lobes
