sporogonium (sp.) has been produced by the female flower, the leaves of 
which now overtop those of the male inflorescence. An older specimen, 
bearing a nearly mature sporogonium, is shown in Fig. 3, in which the 
rhizoids have been entirely omitted. The only essential difference from 
the two preceding cases is that the insertion of the female branch is nearer 
the base of the male axis. 
We have so far relied on the external 
appearance for determining which is the 
parent axis, but naturally it was necessary to 
supplement this by other data. In sections 
cut through the two axes in the region of 
attachment, the structure gave evidence of the 
lateral origin of the female branch. The 
central conducting strand in the male stem 
has a straight or even course. That of the 
female branch, when traced downwards into 
the tuberous base, comes to consist of several 
large, and a few small elongated elements, 
which in the region of attachment run ob- 
liquely across towards the central strand of

the male axis, some of the elements terminating nearly, but not quite, 
in contact with it. A transverse section through the united axes is 
shown in Fig. 4. The female branch ( 9 ) is considerably the larger 
of the two, and its central strand is cut obliquely, as it is beginning 
to curve across towards the male axis. The free base of the female 
branch consists of large-celled parenchyma, and contains no conducting
