sand sida

Sida ammophila is an upright or spreading, perennial shrub to about 80 cm (31 in) high with bluish-grey sometimes brownish branches densely covered in short, matted hairs. The leaves are arranged alternately along the stem, hairy, narrowly oblong or narrowly oval-shaped, 1–5 cm (0.39–1.97 in) long, 2–8 mm (0.079–0.315 in) wide and rounded or heart-shaped at the base. Both surfaces with star-shaped hairs and green-grey or bluish green above, lighter, less hairy below and minute teeth on the margins. Flowers mostly solitary, occasionally in racemes on a pedicel 1.5–25 mm (0.059–0.984 in) long, 5 petalled, pointed, yellow, and corolla 4–5 mm (0.16–0.20 in) long. Flowering may occur any time of the year and the fruit is a mericarp, 4–5 mm (0.16–0.20 in) in diameter, dark brown, wrinkled on lower surface, smooth on upper surface and occasional hairs.

Sand sida grows on sand dunes, sandy soils, sandy ridges in Western Australia, South Australia, Victoria, New South Wales, Queensland and the Northern Territory.
