Annual or sometimes perennial herb with thick fusiform taproot. Stems twining, hairy to glabrescent, up to 3 m long. Leaves cordate-ovate, 20-100 x 15-75 mm, entire, apex attenuate-acuminate to obtuse, rounded basal lobes and sinus, thinly hairy on both surfaces; petiole pilose, 15-100 mm long. Inflorescence a few-to many-flowered involucrate head; peduncle pilose, 20-50 mm long; outer bracts connate into large, pubescent boat-shaped involucre 25-40 mm long with 2 cusps; inner bracts oblong or elliptic, obtuse, ±15 mm long. Sepals unequal, hairy; 3 outer ones oblong to oblong-spathulate, apex obtuse, ±10 mm long; inner ones much narrower, apex acute, 9 mm long. Corolla salver-shaped, pink or white with a darker centre or purple, tube slender, ±20 mm long; limb spreading, 15-30 mm wide; midpetaline areas sparsely pilose. Capsule ovoid, glabrous, 6 mm long. Seeds glabrous or thinly pubescent, ovoid, ±4 mm long, black.
Herbs annual, twining, with ± densely retrorse hispid-pilose axial parts. Stems 1-2 m. Petiole 1.5-6 cm; leaf blade cordate-ovate, 2.5-9 X 2.5-7.5 cm, pilose, more densely so abaxially, base cordate, margin entire, apex acuminate or attenuate. Inflorescences capitate, few to several flowered; peduncle 1.5-7 cm; involucral bracts navicular, tapered at both ends, 2.7-5.5 cm, outside densely pubescent, inside long hirtellous; bracteoles oblong-spatulate, much smaller, villous. Sepals subequal, 8-10 mm; outer 3 elliptic-spatulate; inner 2 narrower, lanceolate, villous, apex obtuse. Corolla pink or purple, salverform, 2.5-3 cm; tube cylindric; limb with deltate lobes, midpetaline bands pilose. Stamens inserted near middle of corolla tube. Ovary glabrous. Capsule ± globose, 5-6 mm in diam. Seeds dark brown, 3-4 mm, glabrous or short pubescent.
Annual, very similar to the last species.. Stems twining, pubescent up to 1 m. long.. Leaf-blade ovate, up to 9 cm. long and 7.4 cm. wide, acute or acuminate, cordate, pubescent; petiole 7 cm. long.. Inflorescence few to many-flowered, enclosed in a pubescent boat-shaped involucre, 2–5.5 cm. broad, the ends of which are blunter than in the last species; peduncle 1–5 cm. long; inner bracts ovate, very obtuse, up to 1.7 cm. long and 1.2 cm. wide, villous at the base.. Sepals ovate, usually very obtuse, about 1.5 cm. long and (l.5–)7 mm. wide, similarly villous.. Corolla pink or white, funnel-shaped; tube 2.5 cm. long, 1.5–2 mm. wide at the base; limb about 1 cm. long and 1.5 cm. wide.. Capsule ovoid, 6 mm. long, glabrous.. Seeds ovoid, subtrigonous, 3.5–4 mm. long, black, glabrous save for traces of pubescence around the hilum.
Twining annual or sometimes perennial herb. Leaves ovate, acute or acuminate, cordate. Inflorescence few-to many-flowered head enclosed in boat-shaped involucre, pedunculate. Outer sepals oblong-spathulate To oblong, obtuse; inner ones lanceolate with long and slender point. Corolla up to 25 mm long. Flowers pink or white with darker centre.
Inflorescence a pedunculate involucrate head, few to many-flowered, enclosed in a 2–5·5 (7) pubescent boat-shaped involucre, 2–5·5 (7) cm. long, originating from the outer bracts, connate, with two cusps; peduncle retrorsely pilose, 1–7 cm. long; inner bracts much smaller, ovate, very obtuse, up to 1·7 cm. long, vilous at the base.
An annual herb. It can have a thick tap-root. The stems are 1-2 m long. The leaf blades are oval and 12.5 cm long by 10 cm wide. The flowers are funnel shaped and white to pink are darker in the tube. Several flowers occur in a group. The fruit is a round capsule 5 mm across.
Sepals 3: outer ones oblong-spathulate to oblong, obtuse, more or less 10 mm. long; inner ones much narrower, lanceolate with a long and slender point, more or less 9 mm. long, all hairy outside.
Corolla funnel-shaped, pink or white with darker centre; tube up to 25 × 1·5–2 mm. at the base; limb about 10 × 15 mm., midpetaline areas sparsely pilose, mucronate.
Leaf lamina ovate, up to 12·5 × 10 cm., acute or acuminate, cordate, pubescent; petiole up to 15 cm. long.
Seeds ovoid, blackish, glabrous or shortly pubescent around the hilum and sometimes on the angles.
Annual or sometimes perennial with a fusiform thick taproot, very similar to I. involucrata.
In all parts more slender than No. 8 (Ipomoea involucrata).
