Description

Brachyscome basaltica is a perennial herb with slender, tufted branches 30–60 cm (12–24 in) long. The leaves are borne either along the aerial stems in clusters at the base of the stems. The branches are smooth or with glandular hairs less than 0.1 mm (0.0039 in) long. The leaves lance, egg-shaped or narrower, sessile, 30–50 mm (1.2–2.0 in) long, 3–14 mm (0.12–0.55 in) wide, tapering at the base. They are more or less sharply pointed at the apex, margins smooth, sometimes with a wavy appearance. The cluster of 10-22 overlapping bracts 3.5–5 mm (0.14–0.20 in) in diameter, individual bracts 2.5–4 mm (0.098–0.157 in) long, 1.1–2 mm (0.043–0.079 in) wide. The bracts soft, dry edges and the outer surface smooth or with a few glandular hairs. The flowers consist of 24-42 white or mauve petals, each petal about 4–6 mm (0.16–0.24 in) long. The one-seeded dry fruit initially flattened becoming more or less swollen at maturity, 1.5–2 mm (0.059–0.079 in) long with small warty protuberances on the surface.[2][3][4]
