The Loco-Weed Disease

Revised edition. "Loco weeds are poisonous plants that have caused heavy losses of horses, cattle, and sheep in some parts of the West and Southwest. Three plants are known definitely to be locoes, a few others are probably injurious, and some suspected ones are harmless. The loco plants, their distribution, characteristics, and effects upon animals eating them, are described in this bulletin. Illustrations of the plants and of poisoned animals accompany the descriptions." -- p. i
