Acrothamnus hookeri, commonly known as the mountain beardheath,[1] is a flowering plant in the family Ericaceae and grows in subalpine regions of southeastern Australia. It is a small upright shrub with oblong-shaped leaves and white flowers.
Acrothamnus hookeri is an upright, occasionally bushy shrub about high with branchlets that are rough. The leaves are oblong-shaped, long, wide, edges mostly smooth but finely toothed toward the apex, upper surface flat to curved outward, lower surface sometimes with a whitish covering and 3 middle more or less parallel veins, and a petiole long. The white flowers are borne in groups of 1–10 in spikes up to long, more or less crowded, at the end of branches or upper leaf nodes, bracteoles broadly oval-shaped, long and the sepals long. The male corolla tube is long, female tubes long, lobes about long and bearded on the inside. Flowering occurs from October to January and the fruit is a fleshy, pink drupe, red when ripe, smooth and long.[2]
Acrothamnus hookeri was first formally described in 2005 by Christopher John Quinn and the description was published in Australian Systematic Botany.[3]
Mountain beardheath grows in montane forest, in heath on wet rocky soils and woodland in New South Wales, Australian Capital Territory and Victoria.[1]
