Gunniopsis calcarea

The shrub has an erect and spreading habit typically growing to a height of 0.1 to 0.3 metres (0.3 to 1.0 ft).

[3] The leaves are bright green with a lanceolate shape and are covered in peltate scales as are the stems.

It is found in tight colonies[1] along roadsides and in depressions in coastal areas of the Goldfields-Esperance region of Western Australia where it grows in sandy, loam or clay soils often over limestone.

[2] The species was first formally described as Aizoon zygophylloides by the botanist Ferdinand von Mueller in 1871 in the work Fragmenta Phytographiae Australiae .

It was reclassified again by Robert Chinnock in 1983 in the article The Australian genus Gunniopsis Pax (Aizoaceae) in the Journal of the Adelaide Botanic Gardens.
