Acrotriche rigida is a low growing shrub in the family Ericaceae which grows in "intricately branched and matted clumps"[1] and is endemic to New South Wales.[3]

Description

Acrotriche rigida is a robust, densely branched shrub, which grows up to 1.5 m high with a corresponding diameter.[2]

The leaves are stiffly spreading and lanceolate (6–11 mm long, 1–1.6 mm wide) and have strongly recurved margins. The leaf itself is whitish, with marked veins (3-5) deeply grooved on the lower surface; petiole 0.8–1 mm long.[2]

The green flowers are usually 4–7 per spike, and have bracteoles which are about 1–1.5 mm long. The sepals 1.4–2.8 mm long and the corolla tube is 2.5–3.5 mm long with lobes 1–1.8 mm long. The plant flowers from July to September.[2]

The ovary has 4-5 compartments and the creamy green fruits are depressed-globose, with a flat top, are about 2.5–3 mm diameter, and are covered in short white hairs, creamy-green.[2]

It is found in dry sclerophyll forest or in scrub on sandstone or granite slopes.[2]
