Stem through all its Branches, breaks out

is to enclofe and protect the other Parts. It 
has received different Appellations, accord- 
ing to the Circumftances with which it is 
attended, v/z. 
PERIANTHIUM, a Flower-cup, when 
its Station is clofe to the Frudtification. If 
it includes the Stamina, and not the Germen, 
it is the Perianthium of the Flower; if the 
Germen, but not the Stamina, the Perian- 
thium of the Fruit ; but if it includes both, 
it is the Perianthium of the Fru@tification.
