Other Comments: O. crassipes is "generally considered the world's most serious aquatic weed" (Rosatti 1987). Originally native to tropical South America, O. crassipes is now a widespread naturalized weed throughout the tropics and subtropics. In the northern part our area, water hyacinth is rare, probably not long persisting. Farther south, it can be an aggressive aquatic weed.
