5. Potentilla emarginata Pursh. 
Lge. Consp. Fl. Groenl. p. 8 & 235. 
Found only in one place, Kakasuak at Kingorsuak, 66° 8’ lat. 
N. 2 small sterile specimens. 
6. Potentilla nivea L. 
Lge. Consp. F. Groenl. p. 8 & 235. 
Found only in one place: 
The west side of Kingorsuak, 66° 8’ lat. N., on a humid, shady 
rocky wall. 
In the above named locality two 20 ctm. high flowering spe- 
cimens, belonging to the main species, were found on the 27* of 
July. In spite of zealous searchings I did not succeed in finding 
the species anywhere else, so that it must at least be very rare 
here, though in West Greenland it grows far more towards the south. 
7. Potentilla tridentata Soland. 
Lge. Consp. Fl. Groenl. p. 10 & 236. 
In table-land, on rocks, on herby slopes, rather rare, between 
66° and 67°5’ lat. N. 
Kingorsuak, Ikerasausak, Akiliarisek. 
The species prefers the interior of the country and thrives 
especially in cracks of the rocks where there is very dry some time 
of the year, but it has also been found on the outer coast in a 
few places. It is rather rare, but grows gregariously where it 
appears. Flowers in the latter half of July; fruit ripens in August; 
old fructifications are common, 
8. Sibbaldia procumbens L. 
Lge. Consp. Fl. Groenl. p. 1! & 236, Berlin Karlvaxter p. 34. 
Hartz Fanerog. p. 391. 
Common on herby slopes and rocks of the table-land above 
the slopes. Flowers from the 20 of June—the 1%* of Aug.; sets 
abundant fruit that remains throughout the winter; old empty fructi- 
fications are common. Forms often dense plantations of a height 
of abt. 5 ctm. |
