Potentilla tridentata, Sot. 
This species is recorded by Duranp, Pl. Kan., p. 191, from Rens. 
selaer Harbour, but as it is hardly found north of the Disco region, there 
has doubtless been some confusion of specimens and consequently it is 
not to be reckoned as a member of the flora of this region any more 
than is P. maculata, Pourr., which Natuorst has through some mis- 
take entered in his table (N. W. Gronl., p. 31) for Rensselaer Harbour. 
Duranp, however, does not record any such plant for that locality 
either in Pl. Kan., or in Enum. pl. Indeed he speaks of a “P. nivea 
B concolor”, which Lance, Consp. Fl. Groenl., p. 6, has thought to be 
P. maculata, but I cannot see any sufficient reason for his conjecture. 
Duranb, indeed, speaks of “two flowerless specimens”, but besides this 
he also describes the flower and gives three localities for it which shows 
that he has had more specimens before him than the sterile ones. Most 
probably the plant from Rensselaer Bay has been P. emarginata. 
Saxifragaceae.

This plant, presumably the most common of all arctic species, seems 
to be equally abundant in N. W. Greenland as in Ellesmereland in 
nearly every kind of vegetation. Still I will give a list of the places 
from whence it is noted.
