The mature archegonium is shown in fig. 3z. There arestl 
vacuoles present towards the base, and a mass of kinoplas 
completely surrounds the egg nucleus. In the center is anothe 
smaller dense area, and at the base a third appears. When ti: 
vacuole is nearer the center of the archegonium, only two kine 
plasmic masses are present, one above and one below. # 
upper one does not always completely surround the nucleus, 
is often only in contact with it at the side. As I have aese 
these masses in some detail in Taxodium, and as they 
almost identical in the two genera, they need not detain us: 
At the tip of the egg cell just under the neck a collection ® 
plastic material is figured, It stains red in saffranin and 0
