It is a twining perennial with pink or white flowers and grows in Tasmania and mainland states of Australia.

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.

[3] Convolvulus angustissimus was first formally described by Robert Brown in 1810 and the description was published in Prodromus Florae Novae Hollandiae.

[4] Australian bindweed grows mostly on loamy or clay soils in woodlands or forests in all mainland states of Australia with the exception of the Northern Territory.
