Characteristics

Perennial, forming much-branched erect to decumbent, annual stems from a woody root-stock. Stems several from base, densely brownish, greyish or sericeo-tomentose, more rarely white-pubescent, up to ±600 mm long, occasionally climbing at ends. Leaves varying from linear-oblong with hastate or sagittate base, with or without basal auricles, to palmately 5-fid, 9-30 x 2-8 mm; covered (as are all vegetative parts, calyx and midpetaline zones) with the same brownish or greyish tomentum as the stems; petiole up to 5 mm long. Peduncles 0-10 mm long, 1-or rarely 2-flowered; bracteoles linear to subulate, 3-5 mm long, sometimes minute. Calyx 6-10 mm long; sepals ovate to oblong, acute to acuminate, occasionally obtuse; outer ones completely covered with tomentum on outside; inner ones with a median hairy zone. Corolla white or pink to pale mauve, with a dark purple centre, widely funnel-shaped, 12-20 mm long, 12-25 mm wide. Capsule globose to ovoid-conical, shortly apiculate, apex glabrous or hairy. Seeds dark brown, glabrous.
More
Perennial herb, up to ± 0.6 m high, covered with brownish or greyish hairs. Stems erect to decumbent. Leaves with blade linear to linear-oblong, base hastate or sagittate to palmately 5-fid, 9-30 x 2-8 mm, thick, margins revolute. Flowers: peduncles 1-or 2-flowered; calyx lobes ovate to oblong, apices acute to acuminate, densely tomentose; corolla 12-20 mm long, lobes distinctly acute, white or pink, with dark reddish purple centre; Oct.-Apr. Fruit a globose to ovoid-conical capsule with apex glabrous or hairy.
Leaf lamina linear to linear-oblong, rhomboidal, ovate-oblong or palmately 5-fid, sometimes emarginate or sagittate with basal auricles, often bifid, subtruncate or cuneate, usually acute, 9–35 × 1–25 mm., nearly sessile, thick, with stout midrib and the lateral nerves impressed above and prominent below, covered (as are peduncles, bracts, pedicels, calyx and midpetaline zones) with same brownish or greyish tomentum as the stems (often bullate or plicate in var. ornatus).
Peduncles up to 5 mm. long, 1 (2) flowered, shorter than the leaves and up to about 30 mm. long; bracteoles small, linear or subulate, about 3 mm. long; pediclels usually longer than the peduncles and up to about 15 mm. long.
