Pluchea is a genus of flowering plants in the stinkwort tribe within the sunflower family. Members of this genus might be known as camphorweeds, plucheas, or less uniquely fleabanes. Some, such as P. carolinensis and P. odorata, are called sourbushes. There are plants of many forms, from annual and perennial herbs to shrubs and trees, and there is variation in the morphology of leaves, flowers, and fruits. The genus was named for the French naturalist Abbé Noël-Antoine Pluche.
