Neoastelia spectabilis

Neoastelia spectabilis is a tufted herb with more or less linear leaves 600–1,650 mm (24–65 in) long and 25–60 mm (0.98–2.36 in) wide with drooping ends, and silvery white on the lower surface. The flowers are arranged in panicles 240–700 mm (9.4–27.6 in) long on a thick peduncle 180–400 mm (7.1–15.7 in) long. Each panicle consists of smaller, many-flowered racemes with a spathe at the base, the individual flowers whitish and 15–18 mm (0.59–0.71 in) wide on a pedicel 4–17 mm (0.16–0.67 in) long. 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.

Silver sword lily grows in rocks crevices near waterfalls and on wet rocks in the New England National Park in Antarctic beech (Nothofagus moorei) forest, at altitudes between 900 and 1,150 m (2,950 and 3,770 ft).
