occur in separate plants, fruit is never produced on the so-called 
male plants, and never on the so-called female unless the males 
occur in the wicinity; several examples are cited in the work of 
Schimper above referred to; when the sexes occur alone, the in- 
erease of the plant is wholly dependent on the propagation by 
gemme or innovations, 
- By the discovery of the antheridia and pistillidia in the other 
higher Cry ptogams, the arguments from analogy greatly strengthen 
the hypothesis of the sexuality of mosses. 
Further observation is required, then, for the direct proof of 
the occurrenct of a ,process of fertilization in the mosses; but 
the facts now before us all tend to prove their sexuality if we 
argue from analogy, and the probabilities deduced from the nega- 
tive evidence above referred to in regard to the dicecious species. 
from some of the cells, some elongating into secondary filaments, 
others at once undergoing a more active development, and by the 
multiplication of their cells, assuming the condition of coni 
forms of moss leaves may soon 
be detected; these cellular masses becoming buds from which 
the regular leafy stems arise.
