Regarding the vertical dist ibekaacine of the species in ee 
P. calycina appears to be confined to the low ground. I have seen 
epiphylla at 2500 ft. on the west coast of Siiiahd, and it Eebasls 
reaches considerably higher. As Neesiana attains a higher altitude 
and latitude in Norway than epiphylla does, it is to be expected that 
it should be found on our hills. On lo oking for it this year up to 
2000 ft., all the plants hitch I saw in fruit were epiphylla. The 
lat tter, however, fruits much more freely than the dioicous species. 
Specimens of P. Neesiana from Moidart have been confirmed by 
Mr. Pearson and Herr Kaalaas. Jungermania endiviefolia Dicks. is 
the same plant as J. calycina Tayl. according to Lindberg; and 
this being so, Dickson’s specific name has priority over Taylor’s for 
our calycina.
