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.

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, tomentose or hairs densely spreading. Stem: decumbent to ascending, 10–100 cm, ± climbing or not. Leaf: < 6 cm, < 9 cm wide (generally much smaller), narrowly triangular to ± reniform; lobes 1–2-tipped; margin generally not wavy; tip acute to acuminate or notched. Inflorescence: peduncle 6–9 cm, < or > subtending leaf; bracts generally ± hiding calyx, 7–20 mm, 5–15 mm wide, entire, lanceolate to widely ovate, generally acute. Flower: sepals 9–15 mm, ± densely hairy; corolla 20–45 mm, white. [Online Interchange]
Plant hairs ± gray (± brown). Leaf: 3–4.5 cm, 3–4 cm wide, ± narrowly triangular; lobes generally 1-tipped; tip ± obtuse to acute. Inflorescence: peduncle 6–9 cm, often > subtending leaf.
