Richardia stellaris plant2

Introduced warm-season perennial, hairless to hairy herb. Stems are prostrate and less than 15 cm long. Leaves are opposite, ovate, 0.7-2.5 cm long and 0.2-0.5 cm wide. Flowerheads are heads of a few to many, small (2-4 mm long), white flowers, with 4 petals and 4-5 sepals. Leaf-like bracts surrounding the flowerheads are nearly hairless on the upper surface. Flowering is from late winter to autumn. A native of South America, it is a weed of disturbed places, such as river flats, stockyards and roadsides. It is only abundant in hard conditions (sandy soils with low water holding capacity) where there is low ground cover or where there has been disturbance from ploughing or flooding. An indicator of disturbance and poor ground cover. Of little importance to livestock grazing, as it usually occurs in low abundance, is very low growing and produces little bulk. Control is rarely required, as abundance is suppressed with healthy vigorous pastures. Herbicides are registered for its control.
