It is a prostrate or erect annual herb with narrow lance-shaped to egg-shaped leaves with the narrower end towards the base, and racemes of yellow flowers with brownish or whitish lobes.

Description

Goodenia psammophila is a prostrate or erect annual herb that typically grows to a height of with multiple stems. The leaves at the base of the plant are narrow lance-shaped to egg-shaped leaves with the narrower end towards the base, long and wide, sometimes with toothed or pinnatisect edges.

Taxonomy and naming

Goodenia psammophila was first formally described in 2001 by Leigh William Sage and Matthew David Barrett in the journal Nuytsia from material collected by Barrett east of Mount Agnes in the West Kimberley region in 1998. The specific epithet means "sand-loving", referring to the usual habitat of this species.
In the same journal, Sage and Barrett described two subspecies and the names are accepted by the Australian Plant Census:Goodenia psammophila subsp. hiddinsiana L.W.Sage & M.D.Barrett, usually an erect plant with dark-headed glandular hairs on the flower parts;Goodenia psammophila L.W.Sage & M.D.Barrett subsp. psammophila, usually a prostrate plant with simple hairs.
The subspecies name honours Major Les Hiddins.

Distribution and habitat

This goodenia grows in sandy soil on flats, ridges and near creeks in the Northern Kimberley biogeographic region in Western Australia.
