cells. x 40. 
Fie. 4. Cuticle of upper epidermis showing papillae and slightly 
sinuous walls of cells. x 150. 
Fie. 5. Cuticle of lower epidermis showing stomata with thickened 
subsidiary cells. x 150. 
Puate VIL. #. Whitbiense. 
Fic. 6. Cuticle of lower epidermis. x 40. 
Fic. 7. Part of the same more highly magnified, showing stomata 
with surrounding subsidiary cells. x 150.
