About Acrotriche affinis DC.
Acrotriche affinis (common name ridged ground-berry) is an erect, heavily branched shrub. It typically reaches a height of around 30 cm (12 in), and has branchlets covered in soft hairs. Its leaves are broadly lance-shaped, measuring 3–11 mm (0.12–0.43 in) long and 1.3–2.5 mm (0.051–0.098 in) wide. The leaves have 5 to 9 roughly parallel veins separated by deep grooves. Flowers are arranged in spikes of 4 to 10 individual flowers, with the entire spike measuring about 2–7 mm (0.079–0.276 in) long. Bracteoles 1.0–1.6 mm (0.039–0.063 in) long grow at the base of the sepals. Sepals themselves are 1.6–2.5 mm (0.063–0.098 in) long. The petals are joined at the base to form a greenish tube 2–4 mm (0.079–0.157 in) long, which is sometimes tinged with maroon, and petal lobes are 1.5–2.0 mm (0.059–0.079 in) long. Flowering takes place from June to October. The fruit is a white, spherical drupe around 3–4 mm (0.12–0.16 in) in diameter. This species grows in coastal areas between the Eyre Peninsula in South Australia and Wilsons Promontory in Victoria, and extends inland as far as the Big Desert.
