Potentilla, tridentata, SOL. 



This species is recorded by DURAND, PI. 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 NATHORST has through some mis- 

 take entered in his table (N. W. Gronl., p. 31) for Rensselaer Harbour. 

 DURAND, however, does not record any such plant for that locality 

 either in PI. Kan., or in Enum. pi. Indeed he speaks of a "P. nivea 

 /? concolor", which LANGE, Gonsp. Fl. Groenl., p. 6, has thought to be 

 P, maculata, but I cannot see any sufficient reason for his conjecture. 

 DURAND, 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.
