Perennial; stems prostrate or twining, densely bristly pubescent.. Leaves ovate, 6.5–17 cm. long, 5–18 cm. wide, acute or acuminate at the apex, cordate at the base, entire or 3-lobed, with the mid-lobe elliptic, thin, green, but adpressedly pilose above, with dense to very sparse and almost nonexistent traces of white-cottony tomentum beneath; veins yellow-bristly beneath; petiole 6–25 cm. long.. Flowers few to many, in lax, rarely rather dense, cymes, very rarely solitary; peduncle up to 23 cm. long; secondary branches up to 9 cm., often forked several times; bracts deltoid, 5 mm. long, 2.5 mm. wide.. Sepals linear-lanceolate to lanceolate, 6–18 mm. long, 2–3 mm. wide, pilose with yellow-bristly hairs; margins glandular.. Corolla pink or mauve, broadly funnel-shaped; tube narrow below, (2.5–)4.5–5.3 cm. long.. Capsule ovoid, 6–9 mm. long, glabrous or pubescent.. Seeds compressed-globose, 3.5 mm. long, yellow-pubescent, also with a small tuft of white hairs 7–8 mm. long.
Perennial with tuberous root. Stems climbing, herbaceous to woody, up to 2.5 m long. Leaves ovate-cordate to suborbicular-reniform, 20-90 mm long, base cordate, sinus broad and shallow, apex acute, margins crenate, entire or 3-lobed, upper surface green, thinly hairy, lower surface softly white-hairy, glabrescent; petioles hairy, 10-50 mm long. Inflorescence lax, 1-many-flowered; peduncle pilose, 20-150 mm long; bracteoles hairy, linear-lanceolate, 7-11 mm long; pedicels up to 15 mm long. Sepals equal, hairy, 10-15 mm long, lanceolate. Corolla funnel-shaped, 40-60 mm long, pink to purple, glabrous or midpetaline areas hairy. Flowering time Nov.-June, mostly Mar.-May. Fruit an ovoid, glabrous capsule, 7-9 mm wide. Seeds ± globose, 3-4 mm long, yellow-pubescent, edges white-hairy.
Leaf lamina ovate-cordate to subcircular-reniform in outline, 2–6·5 × 1·5–5 cm., entire or 3-lobed, acute or acuminate at the apex, thin, green, appressed pilose above, with dense to very sparse and almost non exsistent traces of white cottony tomentum beneath; veins yellow-bristly beneath; mid-lobe elliptic and mucronulate, basal lobes rounded, all constricted at the base and more or less crenate; petiole 1·5–5 cm. long, slender, hairy as in the stems.
Flowers few-to many, in lax, rarely rather dense, cymes, very rarely solitary; peduncle up to 7 cm. long, slender, pilose like the stems and petioles; bracteoles linear-lanceolate, 5–11 mm. long, acuminate-aristate, pilose or hirsute as are the sepals; cyme branches usually short; pedicels 0–10 mm. long.
Corolla broadly funnel-shaped, pink or mauve, 4.5–5 cm. long, glabrous or with a few pilose hairs on the well-defined mid-petaline areas; the limb shallowly 5–lobes.
Thinly hairy, perennial climber to 2 m. Leaves 3-lobed, cobwebby beneath. Flowers pink to purple, sepals thickly hairy, acuminate.
Sepals linear-lanceolate to lanceolate, very acuminate, 6–18 mm. long, pilose with yellow-bristly hairs; margins glandular.
Seeds compressed-globose, yellow-pubescent, also with 2 tufts of long white hairs attached to edges near the apex.
Stems prostrate or twining, slender up to 2·5 m. long, densely bristly pubescent.
Capsule ovoid, glabrous or pubescent.
