Lomandra banksii, commonly known as tropical mat rush, is a species of plant in the asparagus family Asparagaceae. It is native to New Guinea, New Caledonia and the state of Queensland, Australia.

Description

Stem and foliage

Lomandra banksii is a shrub up to 2 m (6 ft 7 in) tall, beginning to flower when about one metre tall. Leaves are long and narrow, up to 30 cm (12 in) long by 8 mm (0.31 in) wide, arranged in tight whorls around the stem. They have numerous longitudinal veins and very fine serrations on the edges; the leaf tip is blunt with one to three indistinct teeth. The leaves separate from the stem close to the leaf base, and the base remains attached to the stem for some time.[4][5]

Flowers

The inflorescence is terminal and about 35 cm (14 in) long, with successive whorls of flower-carrying branches more than 2 cm (0.79 in) apart. This species is dioecious, meaning that pistillate (functionally female) and staminate (functionally male) flowers are borne on separate plants. All flowers are sessile (without a stem) and have six tepals in two whorls of three; male tepals measure up to 3 mm (0.12 in) long and female tepals are up to 5 mm (0.20 in) long.[4][5]

Fruit

The fruit is a capsule about 9 mm (0.35 in) long by 7 mm (0.28 in) wide, with the tepals remaining attached at the base and a sharp point at the apex. They have three segments, each containing a single seed coated in a red aril.[4][5]

Conservation

This species is listed as least concern under the Queensland Government's Nature Conservation Act.[1] As of October 2025, it has not been assessed by the International Union for Conservation of Nature (IUCN).
