Scientific name: Scaevola collaris
Profile last updated:
01 Nov 2022
Description
Hairless erect perennial subshrub to 50 cm high. Leaves are succulent, grey, straight or wider at the tip, 1-8.5 cm long and 1-9 mm wide. The margins of the leaves are smooth, or toothed. The flowers occur at the base of the leaves, 6-17mm long, cream to mauve. The fruit is elliptical, 8-26 mm long, hairless, with a beak to 6 mm long, ribbed.
Distribution
In NSW the species has only been recorded from the Yandama Creek track on the Callabonna-Frome outflow, in the far north west. It is not clear whether the specimen was collected in NSW or SA. However the habitat is similar so the species is likely to occur in NSW. A sample collected in 1979 for the Australian National Herbarium in Canberra was taken from Pimpara Lake on Packsaddle Creek approximately 40km west of the Silver City Highway. This represents the only confirmed NSW record of the species.
Habitat and ecology
- Grows in arid areas, usually on saline soils around salt lakes, and on sand and gypsum dunes and dry creek beds. No herbarium records were found from NSW, however interstate specimens are all from salt lake, floodplain and claypan habitats.
- Associated species include Nitraria billardierei, Acacia salicina, Acacia ligulata, Acacia victoriae subsp. arida, Calandrinia remota, Myriocephalus stuartii, Zygophyllum and Sclerostegia species and other samphires.
- Flowers chiefly from May to November or year-round. Nectar observed to attract flies and beetles in one population.
- Usually recorded as common to abundant in populations.
- An Australian National Herbarium record was taken from the sandy rim bordering Pimpara Lake on Packsaddle Creek. The only habitat note with the specimen was that the species grew with Samphire (Tecticornia) species.
