that the female axis was a branch of the male. We will return to these 
numbers later, after first describing two or three typical specimens. 
When a plant, consisting of a male and female axis, has been isolated, 
it is often the case that the rhizoids form such a dense weft on some 
portions of the stem that the relation of the two axes to one another 
cannot be determined until the greater number of the rhizoids have been 
dissected away. Fig. 1 is a drawing of a plant prepared in this way, 
several rhizoids being also omitted for the sake of clearness. The long 
straight stem is the male axis bearing a terminal discoid male flower (cH), 
in which the antheridia were found to be brown and withered. The branch 
on the right ends in the female flower ( 9 ), which contained one nearly 
mature archegonium, as well as two or three others with brown necks. In 
this specimen it is fairly evident that the female axis has been produced as 
a branch of the male stem. In many cases, especially in older plants, the 
main axis may become bent in such a way that the female branch appears 
at first sight to belong to the primary stem, and the male flower to be on 
a lateral branch, but the removal of the rhizoids makes the matter clear. 
The base of the female branch is usually tuberously swollen, and ends in. 
a short free downward prolongation bearing a large number of rhizoids. 
A plant somewhat older than the last specimen is shown in Fig. 2.
