Neoastelia is a genus of plants in the family Asteliaceae containing the single species Neoastelia spectabilis, commonly known as the silver sword lily,[3] that is endemic to a small area on the Northern Tablelands of New South Wales, Australia.

It is a species of herb with long, linear leaves and large groups of whitish flowers, followed by spherical, pale green berries.

Flowering occurs from November to December and the fruit is an oval to spherical, pale green berry 11–15 mm (0.43–0.59 in) long containing between 70 and 150 small black seeds.

[3][4][5] Neoastelia spectabilis was first formally described in 1987 by J.B. Williams in Flora of Australia from specimens he collected in 1978.

The main threats to the species include trampling by walkers, illegal collection and its small population size.
