in the male filiform or spathulate, and consisting in the upper part 
of several rows of cells. Paraphyses are wanting in the closed bud- 
like flowers of Hypnum. 
The male organs, or Antheridia, consist of cellular sacs, contain- 
ing chlorophyll granules, and are of an elongated club shape, 
assuming, when ripe, a red or yellow colour, and opened by a slit 
across the apex, through which the antherozoids, still enclosed in 
their mother cells, are discharged as a thick jelly, which dissolves

in water which allows the antherozoids to escape and swim about 
free. Fig. 16. 
In the Sphagnacez the antheridia are nearly spherical, and open 
in the same manner as the Hepaticz, the escape of the mother 
cells being occasioned by the access of water and the falling away 
from one another of the cells of the wall. The careful investi- 
gations of Leitgeb show that the origin of the antheridia are very 
various.
