ROSETTE CINQUEFOIL 



Potentilla uniflora Ledebour 



Rosette cinquefoil is a plant seldom seen by the traveler, for it loves 

 rocky places at high altitudes, to which it is hard to climb. It grows 

 in tufts or bunches from a mass of stout, woody, interlaced under- 

 ground stems. Its rich yellow flowers, so large in proportion to the size 

 of the plant, remind one of a small yellow rose. The leaves of this 

 species have three leaflets instead of the five or more possessed by 

 most Potentillas. It belongs to the Rose Family. 



Rosette cinquefoil ranges from Colorado northward through the 

 Rockies to the Arctic regions and westward to Oregon. It grows also 

 in Greenland and Asia. 



The specimen sketched was obtained on the rocky slopes above 

 the source of Ranger Brook in the Sawback Range, fifteen miles west 

 of Banff, Alberta, Canada, at an altitude of 7,500 feet.
