Description

Raleigh Sedge is a small and inconspicuous perennial sedge that grows from underground stems (rhizomes) to 25 cm tall. Its leaves and stem are very thin and wiry. Up to five flowering spikes are clustered towards the ends of the stems, with a leaf-like process (bracts) extending well beyond them. It differs from the similar and associated Carex hebes in having narrower leaves (less than 1 mm, compared to 2.5 mm) and longer, narrower flower-stems (those of C. hebes are generally less than 20 cm long). Unlike C. hebes, its flower-spike is longer than broad.

Distribution

In NSW Raleigh Sedge is found only in areas above about 1000 metres on the Southern Tablelands. Most populations are in Kosciuzsko National Park (eg. Charlottes Pass area, Muellers Pass, Tantangara area and the upper Tooma and Tumut valleys). Also occurs in vicinity of Snowy Plain (private land and travelling stock reserve) and on the coastal escarpment at the headwaters of Tantawangalo Creek within South East Forests National Park.

Habitat and ecology

  • Grows in sphagnum bogs and high mountain wetlands, as well as damp grasslands and stream-edges of sub-alpine plains.
