About Convolvulus angustissimus R.Br.
Convolvulus angustissimus R.Br. (Australian bindweed) has slender, twisted, trailing branches with terete stems that are hairy when young. It grows to a height of 0.02 to 0.6 metres (0.07 to 1.97 ft). Its leaves vary in shape and grow along the full length of stems: basal leaves are oblong to oval, with toothed or slightly lobed margins, and have a heart-shaped or squared base. Upper leaves are ovate to ovate-triangular, 1–6.5 cm (0.39–2.56 in) long and 2–4 cm (0.79–1.57 in) wide, mostly with an acute apex, and petioles 2–20 mm (0.079–0.787 in) long. Flowers are usually borne singly in leaf axils. The corolla is pink, or rarely white, 7–20 mm (0.28–0.79 in) long and 7–20 mm (0.28–0.79 in) in diameter. The terete peduncle is 4–50 mm (0.16–1.97 in) long and covered in flattened hairs. Flowering occurs across all months from January to December. The fruit is globose, smooth, 4–8 mm (0.16–0.31 in) long, and 4–7 mm (0.16–0.28 in) in diameter. This species grows mostly on loamy or clay soils in woodlands or forests. It is found in all mainland states of Australia except the Northern Territory.
