Toxicodendron diversilobum is extremely variable in growth habit and leaf appearance. It grows as a dense 0.5–4 metres (1 + 1 ⁄ 2 –13 feet) tall shrub in open sunlight, a treelike vine 3–9 m (10–30 ft) and may be more than 30 m (100 ft) long with an 8–20 centimetres (3 + 1 ⁄ 4 – 7 + 3 ⁄ 4 inches) trunk, as dense thickets in shaded areas, or any form in between.
In terms of its potential to cause urushiol-induced contact dermatitis, poison sumac is far more virulent than other Toxicodendron species, even more virulent than poison ivy and poison oak. According to some botanists, T. vernix is the most toxic plant species in the United States (Frankel, 1991).
The differences in toxicity in poison ivy, poison oak, and poison sumac are due to differences in the side chains of the chemicals in these plants. In general, poison ivy has a C 15 side chain, poison oak has a C 17 side chain and poison sumac has a C 13 side chain. The dermatitis shows itself in painful and long continued swellings and ...
Unlike Toxicodendron radicans (eastern poison ivy), which often appears as a trailing or climbing vine, T. rydbergii is a shrub that can grow to 1 m (3 ft) tall, rarely up to 3 m (10 ft). The leaves are trifoliate and alternate. The leaflets are variable in size and shape, and are usually 15 cm (6 in) long, turning yellow or orange in autumn.
Toxic effects include vomiting, seizures, and an irregular heartbeat, and death can occur in as little as a few hours. This poison is known as "the poison that keeps on killing" because the toxin stays in the body after the animal dies, so if a predator eats the animal, the predator gets poisoned, and so on up the food chain.
Datura wrightii, commonly known as sacred datura, is a poisonous perennial plant species and ornamental flower of the family Solanaceae native to the Southwestern United States and northwestern Mexico. It is sometimes used as a hallucinogen due to its psychoactive alkaloids. D. wrightii is classified as an anticholinergic deliriant. [1]
