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]

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] 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]
