X. — Epidermal cells deeper and larger 

 in surface extent; outer wall and cuticle 

 heavier; cuticle more strongly ridged; 

 side walls less wavy; more conductive 



X.— Two vessels larger, but not so 

 many small ones; cortex more collen- 

 chymatous; pith cells with thicker walls, 

 pith packed with starch grains and 



and mechanical tissues, but walls thinner. crystals. 

 The mesophyll shows the usual monocot 

 variation, no differentiation into palisade 

 and sponge.
