chromatophores, are seen bear-

different age. Probably they 
may sometimes bear more than 
two, and the production of an-

January to March, and in May I have still found spe- 
cimens with white antheridial branches containing numerous spermatia (no. 5793,

The carpogonia appear atthe end of the summer, and in August young goni- 
moblasts may already be met 
with. The carpogonial bran- 
ches arise in the inner cortex 
or at the limit between the 
cortex and the central tissue; 
they are frequently placed in 
small groups, and two or three 
of them may be given off from 
one of the large storage cells. 
They are almost always two- 
or three-celled. The inferior 
cells of the carpogonial bran- 
ches are globular or ovate, they 
contain one or two nuclei, small 
chromatophores and numerous 
small starch grains. The car- 
‘pogonium is much narrowed
