Discussion

Galactia striata is known from the southern half of Florida.

A. Burkart (1971) recognized three varieties within Galactia striata: var. striata and var. tenuiflora (Klein ex Willdenow) Burkart, both widespread and widely sympatric, and var. crassirachis Burkart, endemic to Argentina. At least seven other varieties have been recognized, as well as various synonyms at specific rank, and this variable complex needs study before evolutionary morpho-geographic patterns are clearly evident. Galactia tenuiflora Klein ex Willdenow is treated as a distinct species in many accounts and is widely distributed.

Galactia striata and G. spiciformis sometimes have both been recognized in Florida and in the West Indies; distinctions observed between them have varied. Most Florida botanists (as well as D. Isely 1998) have treated G. striata more broadly, treating G. spiciformis as a synonym.
