Pluchea is a genus of flowering plant in the Asteraceae family.
Members of this genus might be known as camphorweeds, plucheas, or
less uniquely "fleabanes". Some (like P. carolinensis and P. odorata)
are called sourbushes. There are at least 40 species in the genus.
They are native to tropical and warm temperate areas. Most take the
form of resinous, bushy shrubs. This genus was named for the French
naturalist NoŽl-Antoine Pluche.
