Description
Brachyscome basaltica is a perennial herb with slender, tufted branches 30-60 cm 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 long. The leaves lance, egg-shaped or narrower, sessile, 30-50 mm long, 3-14 mm 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 in diameter, individual bracts 2.5-4 mm long, 1.1-2 mm 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 long. The one-seeded dry fruit initially flattened becoming more or less swollen at maturity, 1.5-2 mm long with small warty protuberances on the surface.

Brachyscome basaltica was first formally described by Ferdinand von Mueller in 1858 and the description was published in Fragmenta Phytographiae Australiae.
