None of the North American or other species of this genus are 
like it, as far as I have been able to find out. 
I have submitted specimens to Herr F. Stephani, who writes: 
“The Hu- saawies areas is certainly a very good species, the 
perianth not bei te.”” 
I have ee pleasure in ee it we Mr. Macvicar, the 
discoverer of it, who has made more important additions to our 
knowledge of the aeotabaiion of the British Hepatice than any 
other botanist for many years.
