Convolvulus angustissimus commonly known as Australian bindweed, is a flowering plant in the family Convolvulaceae. It is a twining perennial with pink or white flowers and grows in Tasmania and mainland states of Australia.

Description

Convolvulus angustissimus has slender, twisted, trailing branches with terete stems, hairy when young and grows to a height of 0.02 to 0.6 metres (0.07 to 1.97 ft). The leaf shape varies and grow along the length of the stems, basal leaves oblong to oval-shaped, margins toothed or slightly lobed and heart-shaped or squared. Upper leaves egg-shaped to triangular egg-shaped, 1–6.5 cm (0.39–2.56 in) long, 2–4 cm (0.79–1.57 in) wide, mostly acute at the apex and petiole 2–20 mm (0.079–0.787 in) long. Flowers usually borne singly in leaf axils, corolla pink or rarely white, 7–20 mm (0.28–0.79 in) long, 7–20 mm (0.28–0.79 in) in diameter, peduncle terete, 4–50 mm (0.16–1.97 in) long, flattened hairs. Flowering occurs between January and December and the fruit is globose shaped, 4–8 mm (0.16–0.31 in) long, 4–7 mm (0.16–0.28 in) in diameter and smooth.

Distribution

It is found on floodplains, along drainage lines and in winter wet depressions in areas along the coast of the South West, Great Southern and Goldfields-Esperance regions of Western Australia where it grows in calcareous sandy loam to sandy-clay soils over ironstone.
