a storage place for the pollengrains, the former is a large 
cavity into which the pollen passes and where the sper- 
matozoids are developed. Later on the upper pollenchamber 
becomes hard and shrivelled. 
The vascular system consists of a sarcotestal complex, 
seven to nine bundles, which branch seldom, running 
from the base to the micropyle and an inner complex 
consisting of twelve to fourteen bundles at the base of 
the seed and branching within the endotesta, till at the 
level of separation of testa and nucellus the number is 
about forty. According to Kershaw (80) these bundles 
would continue their way within the nucellus in contrast 
with the other cycadean-seedbs.

The strobilus and ovules resemble in general form those 
of the genera of the Cycads already described, except Cycas, 
so that Ï shall not repeat the diagnose for Stangeria. 
Lang (84) has examined the development of the young 
ovule and he compares it with the microsporangium of 
Stangeria. 
In the youngest ovules the nucellus is to be seen as a 
free projecting point within the annular wall, the testa or 
integument. The nucellus is marked off from the testa by 
a layer of flattened cells ,which can be traced down from 
the place of separation of the free portions of the integu- 
ment and nucellus” (p. 283). Later on the testa grows in 
its apical region and closes over the nucellus, forming 
the micropylar tube. In a more advanced stage, when 
the testa has considerably thickened, the -micropyle 
forms a long passage, with a narrow external opening, 
widening at its base.
