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 soutce of Ranger Brook in the Sawback Range, fifteen miles west 
of Banff, Alberta, Canada, at an altitude of 7,500 feet. —
