Poison Ivy

Poison ivy

Poison ivy is a type of allergenic plant in the genus Toxicodendron which is native to East Asia and North America. Formerly considered a single species, Toxicodendron radicans, poison ivies are now generally treated as a complex of three separate species: T. radicans, T. rydbergii, and T. orientale. They are variable in appearance and habit, and despite its common name, poison ivy is not an ivy, but rather a member of the cashew and pistachio family (Anacardiaceae).

Poison Ivy (character)

Poison Ivy is a character appearing in American comic books published by DC Comics. Created by artist Carmine Infantino and writers Sheldon Moldoff and Robert Kanigher, she debuted in Batman #181 and has become one of the superhero Batman's most enduring enemies belonging to the collective of adversaries that make up his rogues gallery.

Poison

In science, a poison is any chemical substance that is harmful or lethal to a living organism. The term of poison is used in a wide range of scientific fields and industries, where it is often specifically defined. It may also be applied colloquially or figuratively, with a broad sense.

Hedera

Hedera, commonly called ivy, is a genus of 12–15 species of evergreen climbing or ground-creeping woody plants in the family Araliaceae, native to Western Europe, Central Europe, Southern Europe, Macaronesia, northwestern Africa and across central-southern Asia east to Japan and Taiwan. Several species are cultivated as climbing ornamentals, and the name ivy especially denotes common ivy, known in North America as "English ivy", which is frequently planted to clothe brick walls.
