918 Evans: THE HEPATICAE OF THE BAHAMA ISLANDS 
somewhat aberrant, as Spruce has already pointed out. In 
most of the species which have been referred to this genus the 
female branch is repeatedly floriferous by innovations and thus 
gives rise to a sympodial cluster, which bears a series of flowers 
or perianths along its upper side. In T. obtwsangula there is no 
approach to such acondition. The innovation is frequently com- 
pletely sterile, and even when it is floriferous there is so much space 
between the two flowers that there is no question of a cluster. 
The absence of this particular character indicates an approach 
to the genus Lejeunea, but the other characters of the species seem 
to warrant its retention in Taxilejeunea, especially since other 
species of this genus have been described in which there are no 
distinct clusters or in which such clusters are only occasionally 
developed.
