Acrothamnus hookeri, commonly known as the mountain beardheath,[2] is a flowering plant in the family Ericaceae and grows in subalpine regions of southeastern Australia.

Acrothamnus hookeri is an upright, occasionally bushy shrub about 50 cm (20 in) high with branchlets that are rough.

Flowering occurs from October to January and the fruit is a fleshy, pink drupe, red when ripe, smooth and 2.2–2.6 mm (0.087–0.102 in) long.

[3][4] Acrothamnus hookeri was first formally described in 2005 by Christopher John Quinn and the description was published in Australian Systematic Botany.

[5] Mountain beardheath grows in montane forest, in heath on wet rocky soils and woodland in New South Wales, Australian Capital Territory and Victoria.
