Description
editConostylis setosa is a rhizomatous, perennial grass-like plant or herb that has small tufts and short stems. The leaves are flat, 150–300 mm (5.9–11.8 in) long, 1.5–4.0 mm (0.059–0.157 in) wide, green with striations and glabrous apart from two ranks of hairs on the edges. The flowers are usually borne on up to four flowering stems 80–350 mm (3.1–13.8 in) long. The flowers are white or pinkish maroon to purple, 12–20 mm (0.47–0.79 in) long with lobes 6.0–10.5 mm (0.24–0.41 in) long. The anthers are 2–4 mm (0.079–0.157 in) long and the style is 8.4–12 mm (0.33–0.47 in) long. Flowering occurs from September to November.[2][3][4]
Taxonomy and naming
