Source-derived summary

Gahnia lanigera, also known as the black grass saw-sedge, desert saw-sedge or little saw-sedge, is a species of flowering plant in the sedge family that is found in southern Australia. The specific epithet lanigera means 'woolly'.

Description

The plant is a rhizomatous, tufted perennial sedge growing up to 45 cm high and 2 m wide, with stiff, narrow, sharp-pointed leaves. The flowers are brown. It is a favoured food plant of Antipodia atralba, the black and white skipper butterfly.

Distribution and habitat

The species occurs in arid parts of southern Western Australia, South Australia, north-western Victoria and western New South Wales where it is found on sandy soils in mallee woodland and heathland, as well as on clayey or granitic loams and coastal dunes.

Editorial summary

This brief starts where responsible research should: with the source description of “Gahnia lanigera” as species of plant. Everything that follows is an evidence route, not borrowed authority.

Editorial reviewA practical orientation to terminology and classification, particularly when read beside dated observations, specimens or technical literature. The current 124-word lead offers orientation but no explicit four-digit date, so chronology should not be assumed. The selected authority fields contribute no independent date. The account is most persuasive where Gahnia, lanigera and species can be independently traced.
Editorial analysis

Why this record matters

The subject matters to the science & nature register because the source frames it as species of plant. Its deeper value depends on whether names, dates, institutions and citations support that framing.

Evidence profile

Datasets, specimens, observations and peer-reviewed methods provide the appropriate test for the technical claims summarized here. The source revision retrieved here is dated Feb 18, 2026. The linked authority identifier is Q15591570. None of the 0 selected statements returned an explicit reference.

Critical limits

Scientific names, classifications and consensus can change while older terminology persists in catalogues and historical literature. The lead is largely declarative, so disagreement and counter-evidence require a deliberate search beyond the opening account. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.

How to read it

Check terminology, classification and the date of the cited evidence. Scientific names and technical consensus can change while older records retain historical value.
