Scaevola filifolia is an erect or ascending perennial shrub that typically grows to a height of 50–80 cm (20–31 in) and 30–60 cm (12–24 in) wide. The leaves are linear, thick, sometimes toothed, up to 40 cm (16 in) long and 0.5–2 mm (0.020–0.079 in) wide, light green and fleshy. Abundant white or pink flowers are borne from October to February on a peduncle 10–30 mm (0.39–1.18 in) long, with leaf-like bracts and linear bracteoles 10–20 mm (0.39–0.79 in) long. The sepals are triangular, 1–2 mm (0.039–0.079 in) long, the petals 9–16 mm (0.35–0.63 in) long with lobes up to 14 mm (0.55 in) long and rounded wings up to 3 mm (0.12 in) long. The fruit is elliptic, 3–4 mm (0.12–0.16 in) long.[3][4]
Taxonomy and naming
This species was first formally described in 1810 by Robert Brown who gave it the name Diaspasis filifolia in his Prodromus Florae Novae Hollandiae.[5][6] In 2020, Kelly Anne Shepherd transferred the species to Scaevola as S. filifolia, and the change is accpted by the Australian Plant Census.[1][7] The specific epithet (filifolia) means 'thread-leaved'.[8]
