Rauvolfia (sometimes spelled Rauwolfia) is a genus of evergreen trees and shrubs, commonly known as devil peppers, in the family Apocynaceae.

The genus can mainly be found in tropical regions of Africa, Asia, Latin America, and various oceanic islands.

[3][4] The International Code of Nomenclature for algae, fungi, and plants stipulates that the genus name was established by Carl Linnaeus in his 1753 book Species Plantarum,[5][6] which cites his earlier description[7] which states in Botanical Latin that the name is dedicated "to Leonhard Rauwolf": "Leon.

[12] Rauvolfia vomitoria is a highly invasive species in Hawaiʻi, and is capable of establishing dense monotypic stands.
