The name is derived from the Latin word pecten, meaning "comb." It refers to the marginally-bristled leaves or the pappus form. These plants vary in appearance but they usually bear yellow daisy-like flower heads. Members of the genus are known generally as cinchweeds (current usage) or chinchweeds (older name).
They are native to the Americas, including the West Indies.Keil, D. J. 1975. Revision of Pectis sect. Heteropectis (Compositae: Tageteae). Madroño 23: 181–191.Keil, D. J. 1977.
