LECTURE III. 
Inveftigation of different Genera of the Gaffes One-houft 
and Two-houfes* Of Ferns, 
However extraordinary the flructure of 
the genera juft now confidered may appear, 
there is yet another genus of the clafs Gynan- 
dria which, in the curious mode of it's fructi- 
fication, furpaffes them all ; this is the arum, 
of which the britim plant known by the 
common name of wake-robin, is a fpecies* 
This plant is fubject to great variety in it's 
colours. The part called by children the 
tongue varies from a yellow T ifh green to a 
deep purple ; the leaves and heads differ in 
fometimes being beautifully fpotted with 
black, at others plain green ; the leaves alfo 
are found of different lhapes. This is a won- 
derful flower, and feems intended by nature 
to lhow us, that Ihe is not confined to any one 
method of renewing her productions. Here 
are berries produced with perfect feeds, which 
germinate
