Some wildflowers of Minnesota – this is a PDF of a booklet of wildflower drawings created in 1954 under the direction of Harold Hansen. “The purpose of this booklet is to aid students in the identification of some of the native flowering plants which at one time were very common in this region but which have been forced out by civilization into remote, uncultivated places.” Harold Hansen
