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 Staking out first St. Olaf greenhouse
