gradually larger and closer towards the summit; disti- 

 chous, spreading, of an ovate outline, entire, acute, the 

 apex somewhat incurved ; the body of the leaf may be 

 either considered as formed of two equal lobes, or as a 

 single leaf deeply concave, and carinate in a remarkable 

 manner at the back, with a foliaceous process, especially 

 towards the apex, and disappearing towards the base. It 

 appears to me more natural to view the leaf in this light, 

 and it may be said to bear a striking resemblance to a 

 boat divided transversely in the middle. Fructification 

 unknown. 



The varieties of form in the leaves of the Jungermannuc 

 seem to be really endless. The leaf of the present indi- 

 vidual resembles that of no other species I am acquainted 

 with ; but /. Thouarsii, of Hooker, forms the nearest ap- 

 proach towards it, though widely different in every other 

 respect.

Plant densely tufted, scarcely an inch high, of a dull green 

 colour. Stems erect, very pale, thick for the size of the 

 plant, remarkably tough*, naked for one-half of its length, 

 set towards the summit with a few branches in an alter- 

 nately pinnate manner, the lower ones about two-eighths of 

 an inch in length, and bearing at most three or four minute 

 ramuli. The whole of the upper half of the stem is much
