Conostylis pauciflora is a much-branched, rhizomatous, perennial, grass-like plant or herb with stolons up to 150 mm (5.9 in) long.

[2][3][4] Conostylis pauciflora was first formally described in 1978 by Stephen Hopper in the journal Nuytsia, from specimens he collected 20 km (12 mi) south of Mandurah, overlooking the Harvey Estuary in 1976.

[6] Hopper described 2 subspecies of C. pauciflora in the Flora of Australia and the names are accepted by the Australian Plant Census: Subspecies euryrhipis is common in heath on sand dunes between Cervantes and Yanchep[11][10] and subsp.

pauciflora is found in the Yalgorup-Dawesville area in the Swan Coastal Plain bioregion in the south-western Western Australia.

[12][10] Conostylis pauciflorus is listed as "not threatened",[2] but both subspecies are listed as "Priority Four" by the Government of Western Australia Department of Biodiversity, Conservation and Attractions,[11][12] meaning that they are rare or near threatened.
