Helichrysum calvertianum (F.Muell.) F.Muell. APNI*
Description: Twiggy subshrub to 30 cm high, much-branched; stems glabrescent with sparse woolly and minute glandular hairs, the lower leaves caducous leaving prominent scars.
Leaves crowded, linear, 3–8 mm long, 0.5–0.8 mm wide, margins revolute and concealing the lower surface, surfaces green and glabrous, viscid.
Heads terminal and solitary on branches, hemispherical, 0.7–1 cm long, 1–1.5 cm diam.; involucral bracts with margins woolly-ciliate towards base, laminas reflexed at maturity; intermediate bracts longest with white papery laminas often tinged pink towards the apex, outermost bracts golden and hyaline, innermost with long claws and with small white papery laminas. Florets numerous, all bisexual.
Achenes oblong, terete, minutely glandular; pappus of many barbellate bristles, subplumose at the tip.
Distribution and occurrence:
Grows on or near rock outcrops and platforms (mainly Hawkesbury Sandstone) in dry sclerophyll forest and associated mallee and heath. Restricted to the Southern Highlands region between Joadja, Belanglo, Canyonleigh, Penrose, Fitzroy Falls, Mt Gibraltar, and Berrima. The Mt Gibraltar population was at one stage thought to be extinct but its continued presence is supported by a 2004 collection held at NSW and recent observations. Note added by K.L. Gibbons, 5 July 2021.
