Annual, perennial herb, subshrub, generally twining or trailing. Leaf: 0 or alternate. Inflorescence: cyme or flowers 1 in axils; bracts subtending flowers 0 or 2. Flower: bisexual, radial; sepals (4)5, ± free, overlapping, persistent, often unequal; corolla generally showy, generally bell-shaped, ± shallowly 5-lobed, generally pleated and twisted in bud; stamens 5, epipetalous; pistil 1, ovary superior, chambers generally 2, each generally 2-ovuled, styles 1–2. Fruit: generally capsule. Seed: 1–4(6).
55–60 genera, 1600–1700 species: warm temperate to tropics; some cultivated for food or as ornamental (Ipomoea). [Stefanovic et al. 2003 Syst Bot 28:791–806] Monophyletic only if Cuscutaceae included, as treated here. Ipomoea cairica (L.) Sweet, Ipomoea hederacea Jacq. [Ipomoea nil L., misappl.], Ipomoea indica (Burm.) Merr. (including Ipomoea mutabilis Ker Gawl.), Ipomoea purpurea (L.) Roth, Ipomoea triloba L., all included in TJM (1993), not naturalized. —Scientific Editor: Thomas J. Rosatti.

Key to Convolvulaceae
Perennial herb, subshrub from caudex or rhizome, glabrous to tomentose. Stem: short to high-climbing, generally twisting, twining. Leaf: generally > 1 cm, linear to reniform or sagittate to hastate (deeply divided). Inflorescence: peduncle generally 1-flowered; bracts generally ± opposite, lobed or not, > 1 mm below calyx, not hiding it, small, to < 1 mm below calyx, hiding it or ± so, large. Flower: generally showy; corolla glabrous, white or yellow to pink or purple; ovary chamber 1, style 1, stigma lobes 2, oblong, tips obtuse. Fruit: ± spheric, ± inflated. Seed: generally ± 4.Key to Calystegia
± 25 species: temperate, worldwide. (Greek: hiding calyx, by bracts of some) [Brummitt 2002 Madroño 49:130–131] Intermediates common, often difficult to identify. Molecular evidence indicates close relationship with Convolvulus (Carine et al. 2004 Amer J Bot 91:1070–1085). Bracts qualify as bractlets by some definitions. Leaf blade length measured along midrib.

Perennial herb from rhizome, glabrous to hairy. Stem: climbing, < 4 m. Leaf: blade generally 4–8 cm, lobed. Inflorescence: peduncle < subtending leaf; bracts ± hiding calyx, entire, flat or keeled. Flower: sepals generally 10–18 mm; corolla 30–58 mm, white or pink.
2n=22. Highly variable, many geographic subspecies; other subspecies in temperate regions worldwide. [Online Interchange]
Plant glabrous (densely hairy). Leaf: lobes ± abruptly spreading; sinus rounded to square; tip acute. Inflorescence: bracts 13–28 mm, generally > sepals, 8–18 mm wide, narrowly ovate, flat or keeled. Flower: corolla 30–58 mm, white or pink-tinged.
Marshes, riverbanks; < 500 m. Deltaic Great Central Valley, San Francisco Bay Area, South Coast Ranges, Transverse Ranges, e Mojave Desert (Amargosa River, 500 m); to eastern United States, northern Mexico. Intergrades with Calystegia peirsonii. May–Jul [Online Interchange]
