Description

A tufted perennial herb 20-55 cm high, with a short rhizome. Leaves and culms are glabrous and almost silky smooth with a distinctive longitudinal channel on the leaves. This leaf character is very useful when checking plants that are not in flower. Leaves are also straight and slightly compressible, with minute striations and white markings, which further differentiates the species from others. The narrow, erect flower stem is oblong to ovate in outline, 3-10 cm long, and about 1 cm diameter. The spikelets are more or less numerous and densely clustered, 4-6 mm long.

Distribution

Currently known from wet cliff faces at Blackheath and Wentworth Falls, although due to the inaccessibility of its habitat, many more plants are likely to occur than have been recorded. All known sites occur within Blue Mountains National Park, although they are near the boundary of the reserve.

Habitat and ecology

  • Restricted to seepage areas on steep sandstone rock faces and cliffs in the upper Blue Mountains in New South Wales.
  • Occurs on south, east and west aspects, usually with high light levels and where there is permanent moisture. Plants appear to require little soil as they occur on cliff ledges and rockfaces where there is minimal soil substrate present.
  • It flowers in spring and summer.
