Lechenaultia subcymosa, commonly known as wide-branching leschenaultia,[2] is a species of flowering plant in the family Goodeniaceae and is endemic to the far west of south-western Western Australia.

It is an ascending herb or subshrub with only a few widely spreading branches, narrow, rigid leaves crowded on short, leafy stems, and creamy-white to pale mauve flowers.

Flowering occurs sporadically in response to rainfall, and the fruit is 19–33 mm (0.75–1.30 in) long.

[6] Wide-branching leschenaultia grows in shallow soil over limestone in low shrubland in near-coastal areas on the North West Cape and on islands in Shark Bay, in the Carnarvon, Geraldton Sandplains and Yalgoo biogeographic regions of far western Western Australia.

[2][3] This leschenaultia is listed as "not threatened" by the Government of Western Australia Department of Biodiversity, Conservation and Attractions.
