Discussion

Some treatments of Gouania treated G. polygama (Jacquin) Urban as a synonym of G. lupuloides, but A. Pool (2014) considered them to be distinct species and identified all Gouania in the flora area as G. lupuloides. In the flora area, G. lupuloides is known from Brevard, Indian River, Manatee, Martin, Miami-Dade, and Monroe counties. Gouania polygama occurs in Mexico, the West Indies, Central America, and South America.
