Scaevola collaris is a shrub in the family Goodeniaceae[1] and its native range is five mainland states/territories of Australia: the Northern Territory, New South Wales, South Australia, Queensland and Western Australia.[4]
It is an endangered species in New South Wales.[5]
Scaevola collaris is an erect shrub, growing to 0.5 m.[4][6][7] The stems are erect and smooth.[4][6] The leaves are sessile (i.e., have no stalk), succulent and smooth, and 1-8.5 cm long by 1–9 mm wide.[4][6] The flowers occur in terminal spikes or are solitary or clustered in the axils.[4][6]
The sepals are ovate to triangular, smooth and almost free.[4][6] The corolla is 6-17mm long, smooth on the outside with short hairs on the inside, and yellow to cream or mauve.[4][6] The anthers are free.[7] The ovary is inferior[7] and from 5–20 mm long, is two-celled and usually has a beak and a foot.[6]
It flowers mostly from May to November.[4]
It is found on saline soils in the arid parts of the south of Western Australia, the south of the Northern Territory, South Australia, western Queensland and north-western New South Wales.[4]
It was first described in 1859 by Ferdinand von Mueller,[1][2] and the specific epithet, collaris, comes from the Latin, collaris (having a collar).[8] It was transferred to the genus, Goodenia, in 2020 by Kelly Anne Shepherd and others.[9] Goodenia collaris is the name accepted by the WA herbarium.[10]
