M ARSILE ACE 



In the centre of this tongue which has a tendency to be fold- 

 ed, are two short rows of large cells gorged with fuscous 

 grume. 



Along the centre line of this, about equi-distant between the 

 base and apex, the cells are more grumous, and the lamina from 

 being folded about, here presents a special appearance ; pres- 

 sure shews that they belong to the lamina . 



The scale disappears first, for the male is evident even 

 when the leaves are 4 inches long.
