About

Amaryllis is the only genus in the subtribe Amaryllidinae. It is a small genus of flowering bulbs, with two species. The better known of the two, Amaryllis belladonna, is a native of the Western Cape region of South Africa, particularly the rocky southwest area between the Olifants River Valley and Knysna.

How this plant poisons

Amaryllis belladonna is toxic to humans and to domestic animals, including dogs, cats, and horses. In animals, poisoning usually follows ingestion of the plant, particularly the bulbs. The toxic effects are associated with alkaloids, especially lycorine; several phenanthridine alkaloids have been identified in its leaves, stems, and bulbs, with the bulbs consistently described as the most hazardous part of the plant. In humans, ingestion is reported to cause vomiting, diarrhea, abdominal pain, hypersalivation, and tremors. In animals, reported signs include vomiting, excessive salivation, diarrhea, abdominal pain, respiratory difficulty, ataxia, seizures, and hypotension after larger exposures.
