Lepidosperma avium, commonly named the central Australian rapier-sedge and the desert rush, is a rare species of sedge found in the Everard Ranges of remote northern South Australia and neighbouring parts of the Northern Territory. [1] [2] [3]

Taxonomy

Lepidosperma avium was first scientifically described by Karen L. Wilson in 1994, from the Everard Ranges, which the species is believed to be endemic to. [4] [5]

L. avium shares the feature of having little, spiky branches and flattened flower clusters with several other species in the same genus: Lepidosperma clipeicola , Lepidosperma pauperum (from New Caledonia), Lepidosperma perteres , and Lepidosperma urophorum . [4]

The species epithet refers to the species' remoteness – avium, comes from the Latin avius, meaning isolated or out of the way. [4]

Specimens of the species are held in each of Australia's state herbariums, as well as in the Australian National Herbarium. [6]

Description

Lepidosperma avium forms clumps, between 1.2 and 2.4 metres (3.9 and 7.9 ft) tall. The stems are stiff, hairless, and smooth, less than a centimetre thick, with small lines and grooves all over the surface. [4] [3]

Ecology

L. avium occupies a "petrophilous (rock-loving)" ecological niche. [5] The sedges grow around rocky hills and boulders. The main threats to the species are bushfires. [3]

The Cyperaceae are a family of graminoid (grass-like), monocotyledonous flowering plants known as sedges. The family is large; botanists have described some 5,500 known species in about 90 genera – the largest being the "true sedges", with over 2,000 species.

<i>Rhynchospora</i> Genus of flowering plants in the sedge family Cyperaceae

Rhynchospora is a genus of about 400 species of sedges with a cosmopolitan distribution. The genus includes both annual and perennial species, mostly with erect 3-sided stems and 3-ranked leaves. The achenes bear a beak-like tubercule and are sometimes subtended by bristles. Many of the species are similar in vegetative appearance, and mature fruits are needed to make a positive identification.
