Genus Coronidium Family Asteraceae

Description: Perennial herbs.

Heads predominantly homogamous, discoid. Receptacle ± flat. Involucral bracts in many rows, scarious, spreading when mature; claw of intermediate and inner bracts semi-terete to linear or narrowly oblong, cartilaginous, nerve solitary and extending into the lamina, stereome undivided. Florets bisexual or rarely some outer florets female; corolla narrowly cylindrical, broadened above, lobes short, ovate, nerves extending to base or to apex of lobes; anther tails slender, equal to or exceeding collar, appendage ovate, outwardly concave; style arms slender; style apex truncate, rounded, ovate, triangular or attenuate, strongly papillose.

Achenes cylindrical or oblongoid; pericarp two-veined, either crustaceous, opaque and brown to fawn, or very thin and transparent, smooth, glabrous. Pappus bristles filiform, denticulate, smooth towards base where united in a persistent ring and breaking a short distance above it, or free and persistent, or deciduous as a whole.


Distribution and occurrence: A genus of 17 species endemic to eastern Australia except for two that are also found in south-eastern South Australia of which one extends into Tasmania. 8 species in NSW.

Derived from the Greek words korone a crown, and the diminutive -idion, with reference to the short pappus crown that in the C. oxylepis group of species remains on the achene after the pappus bristles have broken near their base and fallen away.
