Schulz cites a specimen from Niles, Michigan, collected by Wm. 
Boott as belonging here. The plant, however, has the basal leaves 
and the white petals of var. palustris and is apparently an unusually 
small-leaved extreme of that. "Var. angustifolia has either white or 
purplish petals, Professor John Macoun making the statement that 
“All the arctic specimens have purple flowers" (Cat. Can. Pl. i. 
486).
