Tasmannia glaucifolia, commonly known as fragrant pepperbush,[2] is a species of flowering plant in the family Winteraceae, and is endemic to New South Wales.

[2][3][4] Tasmannia glaucifolia was first formally described in 1988 by John Beaumont Williams in the Australian Journal of Botany, from specimens he collected near Point Lookout in 1979.

[6] Fragrant pepperbush occurs in 3 separate areas – the Gloucester Tops and Barrington Tops area, Ben Halls Gap National Park and near Point Lookout in the New England National Park.

It usually grows in soils derived from basalt, sometimes granite, near watercourses in cool temperate rainforest, at altitudes between 1,200 and 1,530 m (3,940 and 5,020 ft).

[3][4] Tasmannia glaucifolia is listed as "vulnerable" under the Australian Government Environment Protection and Biodiversity Conservation Act 1999, and the New South Wales Government Biodiversity Conservation Act 2016 (NSW).
