        According  with McVaugh (1984. Compositae.  in R. McVaugh, Flora
Novo-Galiciana. 13: 440-446) it is possible to find four species of
Galinsoga (G. mollis, G. parviflora, G. triradiata and G. quadriradiata).
All of them are weedy plants that grows almost in everywhere, 1100-2600 m.
No common names are reported for them.
