viii. 96 (1912).— The plant which is passing in America as Arenaria 
laricifolia is more western and northern than A. obtusiloba, occurring 
from Yukon and Alaska to northwestern Wyoming, Nevada and 
Oregon. There is doubt as to just what Linnaeus had as Ar. larici- 
folia and a further doubt as to whether our American plant is identical 
with the European. The material seen by the writer is all frag- 
mentary and until it is better known may pass as A. laricifolia. It 
is highly important to secure abundant flowering and fruiting speci- 
mens for critical study. The following specimens are tentatively 
referred here. YuxKon: Yukon River, August 15, 1887, Dawson;
