Acrotriche halmaturina, commonly known as Kangaroo Island ground-berry,[2] is a flowering plant in the family Ericaceae.

It is a shrub with egg-shaped leaves, curved flowers near ground level with tube-shaped petals, and spherical fruit.

Acrotriche halmaturina is a shrub that typically grows a height of 15–30 cm (5.9–11.8 in) and has the base of stems below the ground, the young stems with reddish-brown hairs.

The flowers are curved with clusters of 8 to 12 on the stem at ground level with narrow bracteoles about 2 mm (0.079 in) long and 1 mm (0.039 in) wide at the base of the sepals.

[2][3] Acrotriche halmaturina was first formally described in 1960 by Betsy Rivers Paterson from specimens she collected near the Western Highway on Kangaroo Island in 1958.
