This and the immediately preceding species of Jungermannia 
(J. squarrosa), though coming from very different parts of the 
world and from totally different climates, have nevertheless a 
very great affinity with each other in the mode of growth, colour, 
the svaly stalk, the texture, and the general form and direction of 
the leaves and stipules. The principal points of distinction be- 
tween them will be found to be the much smaller size of J. jfim- 
briata, and its having the leaves and stipules narrower and 
more deeply cleft, with their segments recurved and their margins 
most beautifully ciliated.
