Above the level of separation of the stony coat and 
the endotesta, the latter be- 
comes free from the nucellus, 
which in its turn points with 
its sharp apical portion into 
the cavity formed by the 
innermost layer. In this way 
three cavities are formed one 
above the other, respecti- 
vely by the cupule, the 
sclerotesta and the endotesta,

À very peculiar behaviour, characteristic of Torreya, 
is what we may call the ,,rumination of the nucellus, a 
very irregular invasion of the endotesta by the nucellar 
tissue. For a more detailed treatment of this progress, I 
may refer to (52) or (53). 
At the base of the seed two vascular bundles enter the 
arillus, running upwards close to the woody integument. 
The orientation of xylem and phloem is normal, the xylem 
lying at the innerside, the phloem outside. They often 
divide but then the different branches always reunite at 
the level of separation of the integument and cupule.
