Carmichaelia (New Zealand brooms) is a genus of 24 plant species belonging to Fabaceae, the legume family. All but one species are native to New Zealand; the exception, Carmichaelia exsul, is native to Lord Howe Island and presumably dispersed there from New Zealand. Carmichaelia ranges in form from trees to prostrate species a few centimetres high. Mature plants are usually leafless, their leaves replaced by stipules which have fused into scales.
