All of the illustrations above are from Wicked Plants: The Weed that Killed Lincoln's Mother & Other Botanical Atrocities. The introduction is rather poignant. Stewart writes, "I didn't write this book to scare people away from the outdoors. Quite the opposite is true. I think that we all benefit from spending more time in nature--but we should also understand its power." It has tons of good information and stunning illustrations.
