Notes

Perennial herb with trailing and twining branches to at least 0.4 m long, but commonly short. Stems cylindrical, moderately to densely hairy in the younger parts, becoming sparser with age. Leaves alternating along the stems, 0.5–6.5 cm long, 2–50 mm wide, variable in shape from the base of the stem to the tip, often 3-5 lobed, surfaces moderately hairy to almost hairless, bases squared off to cordate, margins often scalloped to toothed. Flowers pink with a paler throat, rarely white, funnel-shaped with 5 lobes, 7–25 mm long, 7–25 mm in diameter. Sepals free from each other, 4-7 mm long, inner sepals smaller. Flowers single, rarely paired or arranged as two pairs. Flowering: Spring to Autumn.

Previously included in Convolvulus erubescens, which occurs only in the Sydney area and north from there.

 In a recent review of the Convolvulus, Convolvulus angustissimus is treated as a single variable species without recognised subspecies. However, the subspecies are still recognised by the Council of Heads of Australasian Herbaria (accessed 30 April 2021)
