Carpobrotus glaucescens, commonly known as pigface or iceplant, is a species of flowering plant in the family Aizoaceae and is endemic to eastern Australia. It is a succulent, prostrate plant with stems up to 2 m (6 ft 7 in) long, glaucous leaves, daisy-like flowers with 100 to 150 light purple to deep pinkish-purple, petal-like staminodes and red to purple fruit. It usually only grows very close to the sea.

Description

Carpobrotus glaucescens is a prostrate plant with stems up to 2 m (6 ft 7 in) long and glaucous leaves that are triangular in cross-section, straight or slightly curved, 35–100 mm (1.4–3.9 in) long and 9–15 mm (0.35–0.59 in) wide. The flowers are superficially daisy-like, more or less sessile, 40–60 mm (1.6–2.4 in) in diameter with 100 to 150 light purple to deep pinkish-purple staminodes arranged in three or four rows and white near the base. There are about 300 to 400 stamens in five or six rows and seven to ten styles. The fruit is red to purple, more or less cylindrical, 20–30 mm (0.79–1.18 in) long and 16–24 mm (0.63–0.94 in) wide.

Taxonomy

Pigface was first formally described in 1812 by Adrian Hardy Haworth who gave it the name Mesembryanthemum glaucescens in his book Synopsis Plantarum Succulentarum, but in 1928, Martin Schwantes changed the name to Carpobrotus glaucescens.

Distribution and habitat

Carpobrotus glaucescens occurs in near-coastal areas of Queensland south from near Mackay to New South Wales and the far east of Victoria where it has been confused with C. rossii. It is also found on Norfolk Island and Lord Howe Island. There is a population on the Coromandel Peninsula in New Zealand but it may be an introduced species there.

Uses

The fruit of C. glaucescens was used by Aboriginal peoples as a food source. The flesh of the fruit is said to have a taste similar to salty apples. Early European explorers used the plant as an anti-scurvy treatment. The juice of the leaves can also be used to relieve pain from biting midges and from Portuguese man o' war (Physalia physalis).
