Discussion

In Texas, Galactia longifolia is known from a cluster of five coastal counties in the south: Aransas, Brazoria, Calhoun, Jackson, and Victoria. The irregularly scattered distribution of this species (Florida, Texas, Caribbean, French Guiana, and southern South America) suggests that it may not be monophyletic.
