Other: The genus name, “Cercocarpus”, is from the Greek “kerkos” meaning “tail” and “carpos” meaning “fruit” and refers to the long feathery tails of the fruits. The species name, “intricatus”, means “entangled”.

The family is large and complex and some botanists think it should be divided into more than 1 family. The family is held together by the presence of the hypanthium (a cup-shaped structure on which the calyx, corolla, and often the stamens are inserted).
