Galactia minor
Galactia pinetorum
Galactia minor is known from the Florida panhandle and southern Mississippi and from scattered counties in the other named states.
Galactia minor is distinguished by procumbent, antrorsely strigulose stems, relatively small, congested leaves with glabrous adaxial surfaces and raised venation, few flowers on a short inflorescence axis, and relatively large corollas.

Galactia pinetorum is distinctive in its prostrate (non-twining) stems usually with retrorse hairs, very narrow leaflets with raised venation, and relatively large flowers. Stems of Moldenke collections have antrorsely oriented hairs; this variation is analogous to that seen also in G. brachypoda, G. joselyniae, G. microphylla, and G. smallii. Galactia pinetorum is known only from Brevard, Miami-Dade, and Monroe counties. The other linear-leaflet species of southern Florida, G. grisebachii, has twining stems with consistently antrorse hairs, leaflets without prominently raised venation, and smaller flowers.
