Pectis is a genus of flowering plants in the family Asteraceae described as a genus by Linnaeus in 1759.[4][5][6]

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.[7] Members of the genus are known generally as cinchweeds (current usage) or chinchweeds (older name).[8]

They are native to the Americas, including the West Indies.[9][10][11][12][13]
