Habit | Herbs from slender, elongate woody taproot, usually producing filiform rhizomes at nodes, these producing subterranean flowers and 1-seeded fruits. | Herbs from elongate, cylindric, woody taproot. |
Stems | procumbent, not twining, proximally lignescent, moderately strigose, hairs loosely appressed, retrorse. |
procumbent or trailing, not twining, densely short-strigose, hairs closely antrorse-appressed, hairs 0.1–0.3 mm; internodes usually shorter, sometimes longer, than largest leaflet of adjacent node. |
Leaflets | 3, blades broadly oblong to oblong-obovate, oblong-elliptic, or suborbiculate, 11–35(–42) × 8–30(–35) mm, herbaceous, veins not raised, apex rounded to flat or shallowly retuse, surfaces blue-green glaucous and densely strigose abaxially, sparsely strigose adaxially with closely appressed hairs. |
3, blades elliptic, oblanceolate-elliptic, or oblong-elliptic, (7–)9–25(–30) × (4–)7–10(–18) mm, ± leathery, veins raised on both surfaces, apex rounded to slightly retuse, rarely acute, surfaces sparsely strigose abaxially and lighter colored but not glaucous, glabrous adaxially. |
Inflorescences | flowers 5–8 in pseudoracemes; axis 60–120 mm. |
flowers solitary and axillary or 2–4 in reduced pseudoracemes; axis (5–)10–20(–35) mm. |
Flowers | calyx 5–8 mm, hirsute to strigose-hirsute; corolla pink to pink-red or light purple, 9–11 mm. |
calyx 7–10 mm, strigose, lobes greenish yellow to tan on inner surface when dry; corolla not persisting after anthesis, pink, lighter when dry, 11–17 mm. |

Discussion | 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. (Discussion copyrighted by Flora of North America; reprinted with permission.) |
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.
