Characteristics

Extremely variable perennial, forming several annual stems from a long thin perennial taproot. Stems usually branched only from base, slender, prostrate or occasionally in some forms climbing, usually hairy, usually shorter than 600 mm, but in some forms attaining 1-2 m. Leaves varying from linear or linear-sagittate to hastate-sagittate or oblong with truncate base, usually entire except the often bifid basal lobes, usually somewhat hairy, sometimes densely so or nearly to quite glabrous; petiole usually very short and often hairy. Peduncles 1-flowered or in some forms few-flowered, usually terete, slender, up to 45 mm long, often hairy; bracteoles small; pedicels short or occasionally up to 30 mm long. Calyx usually hairy; sepals varying from lanceolate to orbicular, acute to obtuse, sometimes mucronate or ciliate, 5-9 mm long. Corolla funnel-shaped, white, pale pink or mauve-pink, sometimes with darker pink to reddish purple centre; midpetaline areas hairy near tips, 8-25 mm long. Capsule subglobose, 6-7 mm long, glabrous. Seeds usually 4, dark brown or black, glabrous when ripe, somewhat tuberculate-rugose, 3.5 x 2.5 mm. Flowering time throughout the year, mostly September to May.
