23. Dead horse arum lily
> Scientific name: Helicodiceros muscivorus
> Main habitat: Corsica, Mediterranean islands
The dead horse arum lily, found in Corsica and other Mediterranean islands, smells like rotting meat. The plant’s pungent scent is intended to draw in insects who are trapped the first night after the plant flowers. When the insects are released, they are covered in pollen. The plant is thermogenic, meaning it can produce its own heat, which accentuates the rotting meat smell.

> Scientific name: Dracaena cinnabari
> Main habitat: The island of Socotra, off the coast of Yemen in the Indian Ocean.
The Dragon’s blood tree, found on the island of Socotra, off the coast of Yemen, is related to the palm tree. Its leaves can grow up to 2 feet long. The tree with the distinctive umbrella shape derives its name from its dark resin. This resin, called “dragon’s blood,” has been used for medicine and dyes since ancient times. The tree is considered vulnerable by the International Union for Conservation of Nature because the island is drying out due to climate change.
25. Doll’s eye
> Scientific name: Actaea pachypoda
> Main habitat: Eastern North America
Doll’s eye, a 2-foot tall plant found in eastern North America, produces white berries that have black “pupils” that give the berries the appearance of a doll’s eyes. The deep pink stems provide a colorful contrast to the berries. Looks, however, can be deceiving. The plant, also called white baneberry, is poisonous, and this includes the leaves, stalk, and the berries. Botanists incorporated the word bane, a term used to refer to killer, into names of plants that are toxic.
