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, 1โ6.5 cm (0.39โ2.56 in) long and 2โ4 cm (0.79โ1.57 in) wide, mostly with an acute apex, and petioles 2โ20 mm (0.079โ0.787 in) long. Flowers are usually borne singly in leaf axils. The corolla is pink, or rarely white, 7โ20 mm (0.28โ0.79 in) long and 7โ20 mm (0.28โ0.79 in) in diameter. The terete peduncle is 4โ50 mm (0.16โ1.97 in) long and covered in flattened hairs. Flowering occurs across all months from January to December. The fruit is globose, smooth, 4โ8 mm (0.16โ0.31 in) long, and 4โ7 mm (0.16โ0.28 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.
