L. spicata Desv. were by no means rare. The sand and 
gravel bars at the mouth of the river were covered with 
Chrysanthemum arcticum LL. and Matricaria inodora L. The 
only ferns growing in this locality were Botrychium Lunarta 
Swartz, B. fernutwm Swartz and Aspidium spinulosum Swartz, 
var. dlatatum Hornm. : : 
out sixty miles southwest of the mouth of Big river lie 
two islands, ‘*‘ The Twins” (between lat. 53° 5’ and 53° 20’), 
each about thirty miles in circumference. These islands are 
quite barren, with the exception of a few stunted spruce trees. 
On the northern island there are perhaps not more than a 
score of these, and none of them are above six feet in 
lected. Potamogeton pectinatus L, was common in all ponds, 
and about ecimens in all of the rare P. rutius 
olfg. were secured, one or two ata time. The usual form 
of Epilobium latifolium L. is quite common all around the

Arabis humifusa var. pubescens Wat. and Stellaria longepes
