This most polymorphous species is a great trouble to the young collector, 

 and I used to think the opaque quadrate angular cells sufficient to settle it, but 

 in some forms or in old plants these become pellucid. Again the varieties differ 

 remarkably in size and habit, the leaves however are pretty uniform in structure 

 and afford the best means of identification.
