Perennials. Stems usually de­cumbent to procumbent or trail­ing, rarely twining-climbing, to 10+ dm, densely to sparsely hairy. Leaf blades ± elliptic to triangular-lanceolate or linear and proximally lobed, 10–70 × 2–40 mm, length 1.7–5+ times width, base simple or palmately 2–6-lobed, margins entire or toothed, surfaces densely to sparsely hairy. Inflorescences: flowers 1(–3) per peduncle; bracts lance-linear to lanceolate, 1–3 mm. Flowers: sepals elliptic, oblong, or ovate, 6–12 mm; corolla pink or white, center sometimes purplish to reddish, campanulate to ± rotate, (15–)25–30 mm, limb 5-angled. Seeds granulate or smooth. 2n = 24.


Phenology: Flowering year-round.
Habitat: Grasslands, hills, plains.
Elevation: 0–2000 m.

Distribution

Ala., Ariz., Ark., Colo., Kans., Nebr., N.Mex., Okla., Tex., Utah, Mexico.

Discussion

In the flora area, Convolvulus hermanniae L’Héritier and C. incanus Vahl were long misapplied to C. equitans, and plants of C. crenatifolius were formerly identified as C. equitans.

B. L. Turner (2009) indicated that Convolvulus carrii differs from C. equitans by having herbage more densely silvery-hairy, leaf blades thicker and with veins more pronounced, peduncles longer, seeds smoother, and habitat restricted to fine sands in southern Texas, but these differences are not regarded here as significant.
