 ments often united at the base in 3 or 5 

 sets ; .styles 2 to 5 ; capsules membranace-

 filaments are often in groups, when they 

 are not united. (St. John's wort.) 



PiEo'NiA. Calyx 5-Ieaved; petals 5; 

 styles ; stigmas 2 or 3 ; capsules pod-like, 

 many-seeded. Remarkable for the multi-

 united at the base ; petals 5, deciduous, 

 equal ; stamens 9 to 15, polyadelphous-par- 

 cels alternating with glands ; styles 3, dis-

 celled.

 5, 3-cleft, within the corolla ; capsules 5,
