Taxonomic status:Accepted

Occurrence status:Present

Establishment means:Native

Erect perennial herb to 20 cm high with woody rootstock, sometimes rhizomatous and then sometimes forming extensive colonies; stems and branches closely cottony to sericeous. Leaves often clustered near base of plant, c. linear to narrow-spathulate, 2–6 cm long, 1–10 mm wide, acute to acuminate, apiculate, base attenuate, margins flat or recurved, surfaces cottony, sometimes more densely beneath. Capitula 3–many, congested, campanulate to obconical, 7–10 mm diam.; involucre c. 10-seriate, 4–5 mm long; outer bracts sessile, wholly golden-yellow or tinged brown, shortly ciliate; intermediate bracts longest, erect, long-clawed, c. as long as florets, ciliate, often minutely scabrid near apex. Female florets with 0–4(–5) pappus bristles; bristles shortly plumose in distal half, scabrid below.

This subspecies is a common inhabitant of basaltic grasslands and woodlands of the northern and western plains. The shape and indumentum of the involucral bracts is variable. The variants found in western Victoria grade into the local variant of Chrysocephalum apiculatum subsp. apiculatum, and to the north possibly into C. apiculatum subsp. racemosum (J.M.Black) Paul G.Wilson which has not reliably been recorded for Victoria.
