List of Species of Mosses which seldom or never fruit 
in the British Isles. 
-:o:- 
The list includes the commoner species, and is not exhaustive. Those 
unmarked very rarely fruit. Barren species, (in some cases flowers only have 
been found,) are marked b. Those which fruit more frequenty than the others 
are marked f. 
Fruiting specimens of any in this list may be sent to the Club, fewer of 
those marked f than of the others. 
In marking their Catalogues for Desiderata members may place the sign 
fr. before any species desired in fruit.
