(1948) Gunniopsis papillata, commonly known as the twin-leaved pigface,[2] is a species of succulent plant in the iceplant family, Aizoaceae and is endemic to inland areas of Australia.

It is an annual herb with pimply, spatula-shaped to egg-shaped leaves and flowers with white or yellow petals.

Gunniopsis papillata is an annual herb that typically grows to a height of 20 cm (7.9 in) with cylindrical branchlets.

[2][3][4][5] Gunniopsis papillata was first formally described in 1983 by Robert Chinnock from specimens collected near Curdamurka (west of Lake Eyre) by Joseph Zvonko Weber in 1978.

[4][6] Twin-leaved pigface is found long ephemeral creek beds, swales and in depressions on gibber flats in saline areas, mainly through central and northern parts of South Australia where it grows in loam or clay soils.
