It grows to a height of 0.01 to 0.5 m, and its white-cream/white-blue flowers may be seen from August to November or January.

[4] Scaevola humifusa is a shrub which sprawls along the ground, and is densely covered in short, weak, soft hairs.

The fruit is obovoid, 2–4 mm long, sometimes ribbed, almost without any covering of hairs or scales and is 1-seeded.

[5] It is found in the IBRA Regions of the Avon Wheatbelt, Coolgardie biogeographic region, the Esperance Plains, the Geraldton Sandplains, the Mallee biogeographic region, and the Swan Coastal Plain, growing on sandy and clayey soils, on saline flats,[4] in open heath and mallee.

[5] It was first described and named by Willem Hendrik de Vriese in 1810,[1][2] and its specific epithet, humifusa, is a botanical Latin adjective derived from the Latin, humus (meaning "ground") and fusus (meaning "fell down"), thereby giving an adjective which describes the plant as "spreading over the ground",[6] or "lying on the ground".
