Habit | Herbs from slender, elongate woody taproot, usually producing filiform rhizomes at nodes, these producing subterranean flowers and 1-seeded fruits. | Herbs: taproot slender and fusiform, producing long, white rhizomes that at intervals produce shoots as well as slender, adventitious, fusiform roots. |
Stems | procumbent, not twining, proximally lignescent, moderately strigose, hairs loosely appressed, retrorse. |
procumbent and trailing at least proximally, often climbing-twining distally, strigose, hairs loosely appressed. |
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. |
(5 or)7(or 9), blades elliptic to oblong-elliptic, oblong-lanceolate, or elliptic-oblanceolate, 17–39 × 6–21 mm, herbaceous, veins not raised, apex obtuse to rounded or shallowly retuse, surfaces lighter abaxially but not glaucous, dark adaxially, sparsely strigose abaxially, sparsely strigose to scabrous adaxially. |
Inflorescences | flowers 5–8 in pseudoracemes; axis 60–120 mm. |
flowers 3–11, on distal 1/5–1/2 of axis, sometimes in fascicles; axis 50–150 mm. |
Flowers | calyx 5–8 mm, hirsute to strigose-hirsute; corolla pink to pink-red or light purple, 9–11 mm. |
calyx 7–9 mm, loosely strigose; corolla white, 11–14 mm. |
Legumes | straight or slightly curved, 30–50 × 6–9 mm, densely strigose-sericeous. |
straight, 30–45 × 10–14 mm, loosely strigose to strigose-hirsute. |
Seeds | 1–5. |

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 elliottii is distinct in its pinnate leaves (leaflets 5–9) with coriaceous, dark-drying leaflets, broad fruits, and relatively large white flowers clustered distally on the inflorescence axis. Galactia elliottii is known from scattered areas of Florida plus coastal areas of Georgia and South Carolina. (Discussion copyrighted by Flora of North America; reprinted with permission.) |
