During the past two years many inquiries have been received regarding the possible injurious nature of various plants. In many cases such poisonous plants as "rattlebox," and the “loco weeds" have been sent, while in many others, perfectly harmless plants have been sent to us with assurances of their injurious nature. With a view to calling attention to a few plants that are quite certainly injurious the present bulletin has been issued. It will serve as a preliminary step towards a full investigation of all PLANTS INJURIOUS to STOCK found in our state. It is hoped that stockmen and farmers throughout the state will aid in the work by reporting cases of certain or possible injury done by plants and by sending specimens of plants suspected.
