Description Gnephosis multiflora is an erect annual herb that typically grows to a height of . Its leaves are more or less elliptic or lance-shaped to egg-shaped with the narrower end towards the base, sometimes more or less linear, about long and wide. The pseudanthia are arranged in compound heads of 50 to 250, long and in diameter with 2 to 4 bracts long at base of the heads. The petals are yellow and form a tube long and there are three to five stamens. Flowering occurs in November, and the fruit is a purplish cypsela, long, but there is no pappus.
Taxonomy and naming This species was first formally described in 1983 by Philip Short who gave it the name Chrysocoryne multiflora in the journal Muelleria from specimens collected about "just east of Meckering" in 1978. In 1987, Short transferred the species to Gnephosis as G. multiflora in a later edition of Muelleria. The specific epithet (multiflora) means 'many-flowered'.
Distribution and habitat Gnephosis multiflora grows in sandy saline soils on river flats and the margins of salt lakes in the Avon Wheatbelt and Mallee bioregions of south-western Western Australia.
