Galinsoga quadriradiata is a species of flowering plant in the daisy family which is known by several common names, including shaggy soldier, hairy galinsoga, and fringed quickweed. It is found throughout most of the temperate world, but apparently its native home is Mexico. In Portuguese-speaking countries where it is widely naturalized - e.g. in Brazil - it is known as botão-de-ouro. As an agricultural weed it can reduce crop yields by up to 50%.
