Taxonomy

Dichondra repens was originally described by German naturalists Johann Reinhold Forster and Georg Forster, its specific epithet the Latin adjective repens, meaning "creeping".
Description

The plant is a perennial herb that has a creeping habit, with roots forming at the nodes. The leaves are kidney-shaped to circular and measure 0.5 to 2.5 cm (0.2-1 in) long. The base of the leaf is heart-shaped (cordate) and its apex emarginated or rounded. The upper and undersurface of the leaf are covered in fine hair. The tiny yellowish-green flowers can appear at any time of the year, more profusely from September to February and most so in November. The fruit is a hairy, two-lobed capsule.
Distribution and habitat
Dichondra repens occurs in South Africa. It is found in all mainland Australian states and Tasmania. Within New South Wales it is widespread across eastern and central parts of the state.

It grows on clay or clay-based soils that are medium to high in nutrients in flat places in forested areas. Associated species in New South Wales are river peppermint (Eucalyptus elata), thin-leaved stringybark (E. eugenioides),woollybutt (E. longifolia) and snow-in-summer (Melaleuca linariifolia).
Ecology
The native Pacific black duck (Anas superciliosa) eats the seeds.
Cultivation

This species is cultivated as an ornamental plant, and can be used as a lawn substitute or groundcover in gardens.
