94 WILD FLOWER FAMILIES 
is widely distributed over the Northern States and 
Canada. 
The Rough or Norway Cinquefoil is a third 
abundant species, though it is to be ranked as a 
weed rather than a wild flower. It is a robust, ° 
erect plant, having a coarse appearance that at 
once distinguishes it from either of the above 
named species. There are three leaflets to each 
leaf. The styles are glandular and thickened 
below, and there are about twenty stamens in 
each flower. 
The Barren or Dry Strawberry of the genus 
Waldsteinia has a habit of growth similar to that 
of the Common Cinquefoil, but is at once dis- 
tinguished by its three leaflets. It is widely dis- 
tributed in sparse woods and uncultivated fields 
as far west as Minnesota and as far south as 
Georgia.
