RANUNCULACEÆ (CROWFOOT FAMILY).
* Aconitum napellus.—Aconite (monkshood; wolfsbane) is very commonly cultivated in gardens, and is therefore capable of doing great damage to stock. Horses and cattle have frequently been poisoned by eating the leaves and flowering tops.
* Aconitum columbianum.—The Western aconite, or monkshood, is native in the north-western portion of America, where it sometimes poisons sheep.
Anemone quinquefolia.—The common wind flower, which grows throughout most of the United States, is extremely acrid and poisonous. Cattle seldom touch it. The plant loses most of its poison in drying.
