Flowers often appearing before leaves, solitary or in 2-20-flowered, congested, fascicle-like cymes, borne on older shoots; peduncles and cyme branches very short; bracts minute; pedicel up to 20 mm long, thickening upwards. Sepals 9-15 mm long, accrescent in fruit, glabrous, oblong-lanceolate to ovate, apex acute, mucronate, unequal; inner ones larger. Corolla funnel-shaped, white, mauve to purple, 35-55 mm long, limb as wide, glabrous; mid-petaline areas conspicuous. Capsule elongate-ovoid, glabrous, up to 20 mm long, style base persistent, 10 mm long. Seeds ±12 mm long, elongate-oval, with brownish silky hairs up to 12 m.
Twining perennial shrub, up to 7.5 m high. Leaves ovate to circular or narrowly triangular, abruptly acute or acuminate and minutely apiculate at apex, truncate or cordate at base, entire. Flowers appearing before leaves on older shoots, in fascicle-like cymes. Sepals oblong-lanceolate, acute and apiculate. Corolla 35-60 mm long. Flowers white or purple.
A woody climber. It keeps growing from year to year. It grows 3 m tall. The leaves appear after flowering. The leaves are in groups on new shoots. They are heart shaped and 8 cm long by 5 cm wide. The flowers are in dense clusters om older shoots. The flowers are trumpet shaped and white with a reddish centre. The fruit is an oval capsule.
Leaves borne on the new shoots, more or less fasciculate, deciduous; leaf lamina ovate to circular or narrowly triangular, 3·5–8·5 × 1·3–5·5 cm., abruptly acute or acuminate and minutely apiculate at the apex, truncate or cordate at the base, entire, glabrous or more or less pubescent; petiole 3 cm. long.
Sepals unequal, oblong-lanceolate, acute and apiculate, membranaceous, glabrous, the inner ones larger, 9–14 mm. long, corolla funnel-shaped, white or purple, 3·5–6 cm. long and with the tube constricted at the base, glabrous.
Flowers appearing before the leaves on the older shoots, few to many, congested in fascicle-like cymes; peduncle 0–0·5 cm. long; pedicels 10–20 mm. long, thickening upwards from a slender base; bracts minute.
Stems glabrous or sometimes pubescent when young, firm and woody with greyish or yellowish bark and raised longitudinal ridges when old, oozing sap when cut.
