Hairy Galinsoga is a species of flowering plant in the aster family originating in central Mexico, although it has become naturalized in many other places such as North and South America, Europe, Japan, Philippines, and Northern India. Hairy galinsoga is considered a weed throughout its native and introduced range. As an agricultural weed, hairy galinsoga can reduce crop yields by up to 50%. The genus name commemorates Spanish physician and botanist Mariano Martinez de Galinsoga (1766-1797). The species name comes from the Latin words quadri, "square" and radiatus, "with shining rays".
