The heads Snow-on-the-Mountain’s white flowers are small and contain only disk flowers of 3 to 4 mm long; The heads are known to contain 10 to 30 flowers. The leaves are opposite each other and thin, evidently petioled, sharply serrate, acuminate, the larger ones 6 (to 18) x 3 (to 12) cm long. The stems are 1.5 dm, from a shallow mat of fibrous, perennating roots.

Distribution:
Native from Minnesota to Colorado and Texas

Conditions of Poisoning:
Ingestion, Skin contact

Toxic Principle:
Due to an unstable, fat-soluble alcohol called tremetol, which has a phenyl nucleus and an incompletely characterized resin acid poisoning is possible. Tremetol is an aromatic, oily, straw-colored latex liquid. The principal ketone, tremetone, is also suspected to be toxic.

Clinical Symptoms:
Trembling, especially of the flank and hind legs; slow, lethargic or sluggish behavior (“the slows”); stiffness in movement or ataxia; coma; and death. Horses seem less prone to trembling. Livestock may exhibit constipation, nausea, vomiting, slobbering, loss of appetite, or labored or rapid breathing. An acetone odor on the breath may result from ketosis in severely poisoned animals. Postmortem: gross and histological lesions: fatty degenerative changes in liver and kidney; heart and gastrointestinal hemorrhages. One leaf can kill a child.
