Description

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]

Distribution

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]

Naming

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]
