BRITISH JUNGERMANNIiE. 
I am far from considering it as certain that the above characters are sufficient to distinguish 
this plant specifically from J. furcata; since I can discover no difference but in the hairs, which in 
J. pubescens cover the whole plant, whilst in J. furcata they are either confined to the margin, or, 
at most, to that and the under side. Yet this difference appears to be very constant, and I have 
followed Mohr and Schrader in keeping the two separate.
