Description
editCalotis dentex is an upright, perennial, multi-branched, understory shrub to 80 cm (31 in) high with smooth or slightly hairy, brown stems. The cauline leaves are lance to oblong-shaped, 2–9 cm (0.79–3.54 in) long, 4–11 mm (0.16–0.43 in) wide, margins variable, lobed, toothed, sometimes entire, sessile and with occasional hairs. The white, occasionally mauve flowers are borne on stalks up to 5 cm (2.0 in) long, 7–13 mm (0.28–0.51 in) in diameter, either singly or in a loose cyme from leaf axils and a yellow central disc 5–10 mm (0.20–0.39 in) in diameter. Flowering occurs from October to April and the fruit is a flattened, reddish brown cypsela with several spines 4–6 mm (0.16–0.24 in) long.[2][3]

The specific epithet "dentex" refers to the toothed edges of the leaves.[4][5]
