Scaevola brooksiana is a species of flowering plant in the family Goodeniaceae and is endemic to a small area in the south-west of Western Australia. It is a glabrous, glaucous subshrub with sessile, toothed, circular to elliptic leaves, blue flowers, and wrinkled fruit.
Description Scaevola brooksiana is a glabrous, glaucous subshrub that typically grows to a height of up to and has glossy stems when mature. Its leaves are sessile, round to elliptic and toothed, up to long and wide, the upper leaves stem-clasping. The flowers are arranged in spikes on the ends of branches with leafy bracts and Δ-shaped bracteoles up to long. The petals are blue, about long, glabrous on the outside and bearded inside. Flowering occurs around December and the fruit is elliptic, about long and wrinkled.
This species of Scaevola is distinguished from all other species in the genus by its shrubby habit and glaucous, stem-clasping leaves.
Taxonomy Scaevola brooksiana was first formally described in 1884 by Ferdinand von Mueller in The Victorian Naturalist from specimens collected "in the vicinity of Israelite Bay, discovered by "Miss S.J.Brooke". Although Mueller initially described S. brookeana from specimens collected by "Miss S.J.Brooke", the collector was Sarah Brooks, and in 1889 von Mueller used the spelling S. brooksiana in the second edition of the Systematic Census of Australian Plants. The Australian Plant Census corrected the name following the rules of the Shenzhen Code 2018.
Distribution This species of Scaevola occurs only on Mount Ragged in the Cape Arid National Park, in the Mallee bioregion of south-western Western Australia.
Conservation status Scaevola brooksiana is listed as "Priority Two" by the Western Australian Government Department of Biodiversity, Conservation and Attractions, meaning that it is poorly known and from only one or a few locations.
