The life history of Griffithsia bornetiana
In this condition the tetrasporangium remains for a long time, increasing in size
and in vacuolization of the cytoplasm. The significance of this incomplete
separation of the spores probably lies in the fact that food material seems to pass
up ...

Cryptogams: Algae, Bryophyta and Pterldophyta
Only one pericentral cell of any transverse tier in a fruiting tetrasporophyte
produces a tetrasporangium. Usually, tetrasporangia develop in several
successive tiers. The fertile pericentral cell of a tier is smaller than the other
pericentral cells.
