Convolvulus multifidus Thunb.

Perennial forming annual stems from a woody rootstock. Stems few to many, suberect to prostrate, herbaceous but firm, suffruticose at base, slender, terete, covered (like all young vegetative parts, pedicels, bracteoles and calyx) with a dense villous, tomentose to somewhat silky pubescence, 150-750 mm long. Leaves palmately 5-fid with at least the central lobe irregularly pinnatifid or pinnatisect and basal lobes hastate and bifid, ovate or oblong in outline, 5-35 mm long; ultimate segments always narrow, usually narrower than 2 mm, often with revolute edges or ± concave; upper surface glabrescent, lower surface persistently densely hairy, tomentose or villous; petiole short, up to ±10 mm long in largest leaves. Peduncles 1-flowered, up to 20 mm long, sometimes absent; bracteoles small, linear-subulate; pedicels longer than peduncles, up to 15 mm. Sepals broadly ovate; outer ones 5.5-7.0 mm long, often somewhat thinner and crisped along edges, obtuse or acute; inner ones usually shorter, relatively broader, membranous-coriaceous, glabrous or nearly so except at apex, innermost mucronate to apiculate. Corolla funnel-shaped, very pale pink or white, 10-12 mm long, 12-15 mm wide; lobes rounded to obtuse; midpetaline areas densely silky. Capsule subglobose or ovoid-globose, apiculate, glabrous, ±5 mm wide. Seeds very dark brown or black, glabrous, somewhat longitudinally rugose on back, verrucose-muriculate on angles.
