(type of S. paludosa papillosa). 
The present species was based on Alaska material collected at 
Columbia Fiord by Coville and Kearney, while members of the 
Harriman Expedition (No. 1383). In the writer’s account of the 
Hepaticae of this expedition these specimens were referred to 
S. undulata, a species then understood in a much broader sense 
than at the present time (3, p. 365). In proposing S. cordifolia 
as a new species Miiller spoke of the great diversity which he 
found between sterile plants and those bearing perianths, and he 
emphasized the fact that the fertile plants were scarcely distinct 
from S. dentata, a species not definitely known from America at 
that time but since then reported from numerous scattered local- 
ities. The writer now finds, upon examining Coville and Kearney’s 
material again, that some of the perianth-bearing plants agree 
fully with the sterile plants of Miiller’s description, and that the 
discrepancies between sterile and fertile plants which he em-
