The female strobilus of Cupressus stands terminal on 
short shoots. In the lower part on the axis of these shoots, 
six pairs of decussate ordinary leaves are borne, whereas 
the four pairs of uppermost leaves form the strobilus and 
have the function of sporophylls. Sometimes the vegetative 
leaves are continued above the fertile ones. 
The sporophylls are peltate and in ripe condition their 
rhombic outer surfaces close together and form a berry- 
like structure, which however is not fleshy as is the case 
in Juniperus. Each fertile bract bears in its axil or onits 
uppersurface a different number of flat ovules. 
The outer layer of the integument, a thin sarcotesta 
forms on both sides a small wing lying in the plane of 
greatest dimension of the seed. 
The sclerotesta too is very thin and protrudes in the 
base of the wings, as two sharp ridges. 
À soft endotesta forms the innermost layer. Within the 
integument the nucellus stands entirely free and points 
with the beak ofthe pollen-chamber into the micropylar tube. 
À curious fact has been observed and described by 
Sperk (140), the integument in Cupressus Knightiana ori- 
ginating as two different papillate protrusions, between
