Description Coronidium waddelliae is an erect, multi-stemmed annual or perennial herb that typically grows to a height of about , its stems covered with glandular hairs. Its leaves are sessile, linear, up to long, mostly wide with a few soft, glandular hairs on the upper surface and white, woolly hairs on the lower surface. The flowers are borne in heads in diameter, with several linear bracts at the base and white involucral bracts, the outer bracts sessile and the intermediate bracts narrowly elliptic, long. Flowering occurs from November to May and the cypselas are pale brown, about long with a thread-like pappus.
Taxonomy This species was first formally described in 1945 by James Hamlyn Willis who gave it the name Helichrysum adenophorum var. waddelliae in the Victorian Naturalist from specimens he collected at on Mount Speculation in 1945. In 2008, Paul Graham Wilson transferred the species to Coronidium and raised the variety to species status as C. waddelliae. The specific epithet (waddelliae) honours "Miss Winifred Wadell, who urged Willis "to collect and examine specimens, if fortune should ever bring [him] near the rocky fastness".
Distribution and habitat This species of everlasting occurs in eastern Victoria and eastern New South Wales, where it grows in alpine and subalpine snow gum woodland and heathland, often in rather dry, rocky sites.
Conservation status Coronidium waddelliae is listed as 'vulnerable' under the Victorian Government Flora and Fauna Guarantee Act 1988.
