This Jungermannia is one of the most striking in point of 
size, and the most singular in structure, of any in the rich Men- 
ziesian collection, It is full as large as the J. nobilis (already 
figured), to which it bears at first sight no inconsiderable resem- 
blance. But here the leaves have the lesser lobe, not a conti- 
nuation or expansion of the margin of the larger one, as in that 
species, in J. memorosa and many others ; but it actually grows 
out (if 1 may use the expression) of its superior surface; =i age 
larger lobe itself, particularly towards the extremity, is cut into 
segments so deeply and regularly as to be almost pinnated,
