Flutterby™! :

I don't check in on Marylaine's Neat New Stuff nearly often enough, 'cause it always turns up a gem, like the Colorado State School of Veterinary Medicine and Biological Sciences online Guide To Poisonous Plants. The Poisonous Plant Guide is constructed to enable location of a plant by either knowing the common or botanical name of the plant. Alternatively if the plant is not known, but the disease symptom is, it is possible to search by the presenting clinical sign eg: Abortion, Sudden death, photosensitization.
