Characteristics

Stems herbaceous, slender, twining or prostrate, 1-2 m long, retrorsely to patently pilose. Leaves mostly lanceolate to oblong-or linear-lanceolate, 2½-6 by ½-1½ cm, sometimes ovate-lanceolate to ovate, 2½-9 by 1½-5½ cm, cordate at the base with rounded sinus and basal lobes, long-attenuate to acuminate towards the apex, with an acute or obtuse mucronulate point, sparsely pilose on both surfaces or more densely beneath; nerves 7-8 on either side of the midrib; petiole shorter than or as long as the blade, ¾-8 cm, pilose. Inflorescences axillary, sessile or with a short peduncle, much shorter than the petiole, cymosely 1-3-or sometimes more-flowered. Flowers sessile or pedicels very short, to 3 mm. Bracts pilose, linear or lanceolate, lower ones 3-8 mm, upper ones shorter. Sepals pilose, about equal in length, 7-8 mm, linear-acuminate from an ovate base, the inner ones slightly narrower than the outer. Corolla tubular to funnel-shaped, little exceeding the sepals, 7-9 mm long, pink or purple, darker inside, the tube and the pilose midpetaline bands paler without. Stamens and style included; stamens inserted near the corolla-base, filaments glabrous, the base excepted. Ovary hairy; style hairy at the base. Capsule broadly ovoid to globular, ca 5-6 mm diam., shorter than the sepals, hairy, crowned by the hairy style-base, 2-celled, 4-valved. Seeds 4, ca 2½ mm long, glabrous, minutely reticulate.
