walls and the spermatogenous tissue are antheridial characters; several 
similar organs were found 
Fic. 41. A young normal antheridium; in mature antheridia distinct 
regions of spermatogenous tissue can be detected representing each of these 
primary cells. 
Fic. 42. A young archegonium with a cell cut from the lower part of 
central cell; whether the larger cell represents the ventral canal cell and the 
smaller one the egg could not be definitely determined. 
Fic. 43. A venter containing two eggs and two ventral canal cells; 
whether the upper cell is the lowest canal cell divided or the original ventral 
Ba cell divided could not be determined. 
44. A double venter with two eggs; all cross walls have disap- 
wae 
Figs. 45-46. Abnormal antheridia; in each case the mass of sperma- 
togenous tissue is separated by the primary walls into distinct regions charac- 
teristic of antheridia; each organ has an outlet of two axial rows which 
before reaching the apex becomes one row; in fg. 6 there are two masses 
of sperm tissue, each with its own axial outlet; the pedicels and necks are 
distinctly archegonial characters. 
- A modified archegonium with traces of two a rows, and a 
mass ab: sperm mother-cells developing in the elongated pedice 
FiG. 48, a—f. Cross-sections of an archegonium from the ae cell to 
the lower part of the pedicel; the middle cell and the three peripheral cells 
cut from it shown in J, the central cell and double wall of venter are shown 
in 7; and the quadrate character of the pedicel in # and o. 
_ 49, af. Cross-sections of an archegonium from terminal cell to 
base of pedicel; the massive character of pedicel shown in fz, the four 
basal al, not divided (f).
