climbing-twining, proximally lignescent, hirsute-strigose to strigose, hairs loosely appressed, retrorse.
procumbent, sometimes weakly twining distally, herbaceous or proximally lignescent, loosely strigose, hairs antrorse or retrorse.
3, blades elliptic to broadly elliptic or oblong-elliptic, (15–)20–42 × 10–25(–32) mm, herbaceous, veins raised or not on both surfaces, apex obtuse to rounded or shallowly retuse, surfaces not glaucous, sparsely strigose with closely appressed hairs to softly hirsute with ascending hairs abaxially, glabrous to sparsely strigose adaxially.
3(rarely 5), blades usually broadly oblong-elliptic to suborbiculate, sometimes broadly oblong to broadly oblong-oblanceolate, (9–)11–29(–37) × 6–24(–34) mm, herbaceous, veins strongly raised on abaxial surface but not adaxially, apex rounded to truncate or retuse, surfaces light green to glaucous (beneath vestiture), densely hirsute-strigose to loosely strigose-sericeous, sometimes more densely so along abaxial veins.

Galactia texana
Galactia joselyniae
In Texas, Galactia texana is known from east-central counties southwestward to the Big Bend region.
Galactia texana is characterized by its twining stems, relatively short, few-flowered inflorescences, and falcate fruits.

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.
