For the most part the inner integument suffers compression 
ofits elements and can be distinguished with difficulty. Of 
the nucellus nearly all the cells suffer absorption. An ex- 
ceptional region is seen at the base of the ovule. Here a 
considerable quantity of the compressed tissue remains, per-
