Description

[edit]

Conostylis drummondii is a rhizomatous, tufted perennial, grass-like plant or herb that forms tufts up to 20 cm (7.9 in) in diameter. Its leaves are more or less round in cross-section, 100–300 mm (3.9–11.8 in) long and 0.5–1.5 mm (0.020–0.059 in) wide and densely covered with fine, woolly, feather-like hairs pressed against the surface. The flowers are arranged in small groups on a hairy flowering stalk 50–80 mm (2.0–3.1 in) long with woolly-hairy bracts. The perianth is pale lemon-yellow, 6–9 mm (0.24–0.35 in) long with lobes 4.0–5.5 mm (0.16–0.22 in) long. The anthers are 2–4 mm (0.079–0.157 in) long and the style 5–7 mm (0.20–0.28 in) long. Flowering occurs in late October and November.[2][3]
