Herbaceous perennial. Stems many, long, slender, weak, climbing or prostrate and usualÂly branched, pubescent or farinose-puberulous, younger shoots often silvery. Leaves usually cordate-deltoid or sagittate, acute with terminal mucro, rarely obtuse, subentire to irregularly and shallowly crenate, herbaceous drying memÂbranous, glabrous above except when young, glabrous or somewhat pubescent beneath, disÂtinctly net-veined; basal sinus broad, basal auriÂcles rounded or pointed, sometimes with a few teeth; very rarely leaves with additional trianguÂlar lobes above basal auricles; blade 40-120 mm x 30-90 mm; petiole up to 65 mm long, finely and densely pubescent. Peduncles as long as, or longer than subtending petiole, finely pubescent, subumbellately 1-6-flowered; bracts minute, linear or lanceolate, pubescent; pedicels short. Sepals unequal, oblong or elliptic (outer ones) to suborbicular (inner ones), much imbriÂcate, acute or obtuse with terminal mucro, 6-8 mm long; 2 outer ones somewhat pubescent; 3 inner ones less pubescent to almost glabrous and wider. Corolla funnel-shaped, white, very pale pink or very pale pinkish mauve, 12-15 mm long; lobes short, tube rather narrow; mid-petaline areas hairy towards obtuse, mucronate tips of lobes. Stamens bearing short thick laterÂal papillae in their dilated basal portions; anthers dirty purple. Ovary glabrous. Capsule subglobose, shortly apiculate, glabrous, 5-8 mm wide, pale brown. Seeds usually 4, sub-trigonous, 3.5-4.0 mm long, black, scabridulous-rugose. Flowering time throughout the year.
