found in N. pilosa, so that their reference to N. rupestris is probably 
correct. It is to be regretted that no satisfactory specimens of N. 
pilosa were collected, although the cliff where F. G. Floyd found his 
material was visited. "This was very likely due to the fact that the 
plants were collected after they had passed their prime, so that it was 
difficult to distinguish between similar species in the field. It should 
be borne in mind, however, that N. pilosa and N. rupestris are very 
closely related species and that there is some possibility that they 
may not be distinct. Schiffner has already mentioned this possibility 
and describes a region in the Tirol where Neesiella carnica (Massal.) 
Schiffn., a species doubtfully distinct from N. pilosa, grows in company 
with plants which cannot be distinguished from N. rupestris and also 
with plants which seem to be intermediate between N. carnica and 
N. rupestris! He suggests two explanations: first, that the specimens 
of apparent N. rupestris may actually represent true N. rupestris, in 
which case N. carnica and N. rupestris would be synonymous; second, 
that they may simply represent individuals of N. carnica, so affected 
by deep shade and increased water-supply that they resemble N. 
rupestris in all respects. He hesitates to decide the question on the 
basis of what he found in a single locality but recommends it for the 
consideration of others who may be fortunate enough to make observa- 
tions upon these rare plants in the field. If it should ever be estab- 
lished that N. pilosa, N. rupestris, and N. carnica were synonyms, 
the species would have to bear the name N. pilosa on the ground 
of priority.

North America. In Europe the species is known from a few scattered 
localities in Norway, Sweden, Finland, Denmark, Germany, and 
Switzerland. The material from Vermont is destitute of sexual 
organs but bears gemmae in abundance. It agrees closely with the 
specimens distributed by Schiffner (as a new variety humilis) in his 
Hepaticae Europaeae, No. 116. At first glance the species bears some
