Type.
Herb. Linn. No. 219.3 (LINN), designated by Wijnands (1983: 88).
Description.
Annual herb, stems glabrous except on nodes. Leaves petiolate, entire, 5-8 × 3-5.5 cm, ovate to coarsely dentate, acute and mucronate, cordate, usually sagittate with dentate auricles, glabrous except on the veins beneath; petioles 2.5-5.5 cm. Inflorescence of lax, few-flowered cymes; peduncles 1-13 cm; bracteoles 1-3 mm, broadly lanceolate; pedicels 5-15 mm, eventually becoming reflexed in fruit; sepals unequal, outer 3 mm, oblong to elliptic, rounded to obtuse, smooth, the mucro 2-6 mm, the inner c. 5 mm long, oblong, the mucro 2-5 mm; corolla tube 2-2.5 cm long, lobes 0.5-1 cm, virtually undivided, red or red or variegated with yellow, glabrous, stamens exserted. Capsules broadly ovate, muticous or shortly rostrate, c. 7 mm, glabrous; seeds uniformly tomentose.
Distribution.
Endemic to southeastern USA, where it grows on waste ground, roadsides, stream sides and in ditches, apparently with a preference for seasonally moist habitats.

Notes.
The name Ipomoea coccinea is still commonly but erroneously used for many different species in this clade.
Some specimens from outside the eastern United States may be correctly named Ipomoea coccinea , for example Martínez 31473 (BM) from Campeche, Mexico. These merit further investigation.
• Species 328-334 form another well-defined small clade characterised by their palmately (sometimes pedately) lobed leaves and mucronate sepals. Most species are annuals. It is centred on Mexico and, following House (1908b) can be referred to as the Pedatisecta Clade
