Galactia pinetorum
Galactia canescens
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.

Galactia canescens is characterized by its prostrate, strigose stems rooting at the nodes, slender rhizomes often bearing subterranean flowers and fruits, and broadly oblong to suborbiculate leaflets with glaucous and densely strigose abaxial surfaces. It is found in more than 20 counties in Texas.
