Presentation transcript:

Mountain Mahogany (Cercocarpus montanus) Three varieties of mountain mahogany grow in Texas. Members of the rose family. Toxic agent contains concentrations of cyanogenic glycosides and under certain conditions may develop hydrocyanic acid (HCN)

Chokeberry, Wild Plum, Wild Cherry (Prunus spp.) Shrubs or small trees with alternate or bunched, simple leaves belonging to the rose family. Several species of Prunus produce hydrocyanic acid (HCN) under certain conditions.

Dutchman’s Breeches (Thamnosma texana) Perennial weed that is a member of the citrus family. Toxic properties can be attributed to the presence of photosensitizing linear furocoumarins (psoralens) in the plant.

Jimsonweeds, Thornapples (Datura spp.) Several species of jimsonweeds grow in West Texas. Toxicity results from a high content of tropane alkaloids (atropine, scopolamine, hyoscyamine) Livestock and people can be poisoned by eating an part of the plant.

Silverleaf Nightshade (Solanum eleagnifolium) An upright, prickly perennial in the potato family, usually 1-3’ tall. This plant has reportedly poisoned horses, sheep, goats, cattle and people. However, sheep and goats resist it more than cattle. Toxic agent is solanine.
