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.)

Key to Convolvulaceae

Perennial, 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, swollen.
Fruit: ± spheric, ± inflated.
Seed: generally ± 4.
± 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. Lf blade length measured along midrib.

Perennial from rhizome, generally glabrous.
Stem: decumbent to ± erect, 10–50 cm.
Leaf: blade generally 2–4 cm, generally triangular- hastate to reniform; lobes not clearly defined, directed ± laterally, truncate to wedge-shaped or widely rounded, occasionally with shallow sinus.
Inflorescence: peduncle < 5 cm, generally < subtending leaf; bracts not fully hiding calyx, 8–12 mm, 3–9 mm wide, ± cordate-elliptic, entire, ± obtuse.
Flower: sepals 10–15 mm; corolla 30–45 mm, white (pink-tinged).
Dry, rocky places in open forest, chaparral; 600–1200 m. Klamath Ranges, High Cascade Range, San Francisco Bay Area.
