markable featuré in this little plant 1s the dense covering of starry 
pubescence or tomentum, which gives the appearance of some 
Jungermannia of the tomentella-group, and the colour is, in all 
the specimens I have yet seen, ferruginous or tawny-brown on 
one side and pale grey on the other—a circumstance I can only 
account for by supposing it to grow in masses, of which one sur- 
face is exposed to a strong light, while the other side is bleached 
by the absence of light. The involucres are all at the apex of 
the branches, which seem to be swollen and hollowed out for 
the reception of the columella and capsules.
