Tetragonia fruticosa, or kinkelbossie, is an endemic Southern African coastal perennial shrub or scrambler, well-suited to dune sand stabilisation and often browsed by livestock and game.

It is found from sea-level to about 1100 metres.

[1] The fruits are unusual for Aizoaceae being four-winged, single-seeded and indehiscent.

The wings are green and succulent at first, drying and becoming papery and brown, aiding in dispersal of the seed by wind.

[2] The flowers are a rich source of pollen and nectar for honeybees.
