Isotoma anethifolia is an upright, perennial herb with wiry stems to 40 cm (16 in) high and may have either smooth or short soft hairs. The narrow leaves are egg-shaped to elliptic, 6–10 cm (2.4–3.9 in) long, 6–50 mm (0.24–1.97 in) wide, leaf edges pinnatisect and the undivided sections 1–2 mm (0.039–0.079 in) wide, each lobe about 0.5–2 mm (0.020–0.079 in) wide. The star-shaped flowers are mostly white with a light shading of mauve or pink and single in leaf axils. The floral tube is 10–20 mm (0.39–0.79 in) long, lobes are lance to oblong shaped, pointed and occasionally toothed. The bracts shed early, peduncles 4–13 cm (1.6–5.1 in) long and calyx lobes 3–8 mm (0.12–0.31 in) long. The seed capsule is elliptic to cone shaped and 5–17 mm (0.20–0.67 in) long. Flowering occurs in spring and summer.[2][3]
This species was first formally described in 1932 by Victor Samuel Summerhayes and the description was published in the Bulletin of Miscellaneous Information, (Royal Botanic Gardens, Kew).[4][5] The specific epithet (anethifolia) is derived from the Latin anethum- meaning "anise" and -folius meaning "leaved".[6]
In New South Wales this species grows north of Ebor, in moist, rocky, humus rich soils usually on granite.[2]
