CHAPTER III 
GAMOPETAL (COROLLIFLOR/) 
N this group the flowers have both calyx and 
corolla, being dichlamydeous, and the petals are 
united. The petals bear the stamens and are connate, 
and united into a two or more lobed corolla. The 
group is also called Monopetale or Corolliflore. 
When the ovary is inferior the stamens are 
epipetalous, when superior the stamens are also 
epipetalous, and the corolla may be regular or irre- 
gular. 
In some Ericacez the petals, however, are free, as 
in Pyrola and Monotropa, and in Plumbaginez. 
There is no corolla in Oleacez, in Fraxinus, or in 
Glaux amongst Primulacez. 
Instead of being epipetalous the stamens are 
hypogynous in Ericaceze and Oleinez, in Fraxinus, 
in Littorella, in Plantaginez, and in Plumbaginez. 
There are twenty-three families in this group, of 
which we have included nine, and we have described 
twenty species in illustration of these families.
