“Too much cannot be said in praise of the 120 pages of flower paintings contributed by Miss Mary E. Eaton, of the New York Botanical Garden. Those best qualified to judge regard Miss Eaton the greatest of living wild-flower painters. She has not only painted the likeness of the flowers with   the highest botanical accuracy, but she has been able also to put the very  soul of the plants into her paintings.”

William Joseph Showalter, Washington, D.C. 1924 in the Foreword to the National Geographic Society, The Book of Wildflowers.
