Discussion

The geographic distribution of Bigelowia nuttallii is discontinuous, skipping from its area of greatest abundance in Texas and central Louisiana to scattered sites in northeastern Alabama, Georgia, and Florida (where partially sympatric with B. nudata var. nudata). Polyploids are known in populations in Georgia and Florida and are morphologically indistinguishable from the diploids.
