Galactia canescens
Galactia joselyniae
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.

Galactia joselyniae is similar to G. wrightii in its mostly trailing stems and densely hairy leaves but different in its cauline vestiture with hairs either antrorse or retrorse, smaller, broadly oblong to suborbiculate leaves, and smaller and fewer flowers. It is known from Texas populations in Brewster County (Dead Horse Mountains, near the Rio Grande within side drainages of Boquillas Canyon) and Jeff Davis County (Wild Rose Pass) and from one collection in central Coahuila about 300 km south of the Brewster County sites. Plants in Brewster County have loosely strigose stems with antrorse hairs; those in Jeff Davis County and in Coahuila have strigose stems with retrorse hairs.
