Às in Cephalotaxus and Torreya the endotesta becomes 
free in its upperpart from the stony layer and covers 
the nucellus, without being fused with it. 
The nucellus itself is bordered by a well differentiated 
epidermis. The embryosak within enlarges very rapidly 
after fertilisation, so that when the seed is mature, 
the nucellar tissue is only represented by a thin mem- 
brane. 
The micropyle after pollination ,,becomes closed by the 
centripetal radial growth of a portion of the inner epi- 
dermis of two sides” (56). 
At the base two to four vascular bundles enter the 
ovule at opposite sides, running through the integument 
almost to the micropyle. Their course corresponds to the 
ridges on the testa, sometimes the number being three or 
four. The two vascular bundles are formed by fusion out 
of four bundles in the axis, beneath the base of the seed,
