Description

It is a succulent, erect to decumbent herb, flowering from September to November with white-pink flowers. It grows on sandy and gravelly soils on granite outcrops and slopes.[3] The flowers are on pedicels (stems) which are 0.5–2 mm long and erect when in fruit. The bracts are alternate. The sepals are deciduous and 1.5–3 mm long. There are 5-7 petals, 5-10 stamens and 3 stigmas. The black capsule is almost spherical with three short valves which open at the apex only. The numerous, red-brown, shiny seeds are about 0.5 mm long and 0.4 mm wide.[5] For an illustration of the colliculate seeds, see PlantNet.

Taxonomy

The species was first described as Calandrinia granulifera by George Bentham in 1863.[2][6] The genus Calandrinia was discovered to be paraphyletic, and the Australasian species were moved to genus Rumicastrum in 2020.[1][7]
