ARCTIC MOSSES. 
Elizabeth G. Britton. 
The American Museum of Natural History sent to the New York 
Botanical Garden for determination, the plants collected by Lieutenant 
Peary in Grant Land 8i° 40' in 1902, and by Dr. L. J. Wolf at Wrangle Bay, 
Lincoln Bay and Grant Land 82° 27 ' in 1906. 
The mosses were sent to Dr. Bryhn, a specialist on Arctic mosses who 
has also determined the mosses of the Amundsen Expedition of 1903-1906 
and published the combined results in Christiana, Norway, under the title of 
Bryophytorum Arcticorum.* 
The Peary collection included 62 bryophytes of which 57 were mosses 
and 5 hepatics. Of the mosses one species and two varieties were new, 
Bryum Pearyanum being dedicated to the commander of the expedition. 
Some of the species are peculiar to arctic regions, all are depauperate 
and much mixed, and are remarkable as growing further north than those 
of any previous collection. 
Only four of the mosses were fruiting, Tetraplodon mnioides , Voitia 
hyperborea, Bryum pendulum and Polytrichum alpinum. The sterile 
species were; Dichodontium pellucidum, Dicranum spadiceum obtusum n.
