#azioaceae

"Three-angled Four-Angle", refering to the way the fruit usually contains three seeds, instead of the four common in the rest of the genus.

Synonyms include Tetragonia expansa var. strongylocarpa, Tetragonia strongylocarpa and Tetragonia implexicoma var. chathamica.

Native to Lord Howe and Norfolk Islands, and New Zealand. Despite the common name, not just known from coastal areas, although it's certainly most common there. Sometimes in farmland where it grows in hedges or on alkaline outcrops in otherwise dense forest.

Edible, if used like spinach or kale.

Another Ice Plant well-adapted to survive Western Australia's scorching summers and droughts. Unlike the sandfig previously, this one is actually native to the Mediterranean region, and has become an invasive weed in South Africa, Australia, the SW US and Mexico, and other places with similar climates.

The genus Cleretum was established by English succulent expert Nicholas Edward Brown in 1925. He based the diagnosis on a herbarium sheet that was later discovered to contain parts belonging to plants in different genera, and without designating a holotype. To say that this caused later headaches in an understatement.

An Ice Plant native to South Africa, that unfortunately finds the climate and appalling soils of the Western Wheatbelt entirely to its liking. The fruit and leaves are edible, both as as a snack and for their flavour, but is apparently toxic to live stock, probably because they eat much more of it.
