Common Name: MORNING-GLORY
Habit: 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.
Etymology: (Greek: hiding calyx, by bracts of some) Note: 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.
