Synonyms: Olearia phlogopappa var. subrepanda (DC.) J.H.Willis APNI*

Description: Erect shrub up to 1 m high; branches densely stellate hairy.

Leaves alternate, sessile to subsessile; elliptic to obovate, 5.0–16.5 mm long, 2.0–6.5 mm wide; margin entire to crenate, flat; apex obtuse, base attenuate; upper surface greyish, moderately stellate-hairy, undersurface whitish-grey, sometimes yellowish when young, densely stellate-hairy, hairs tightly packed; hairs subsessile multiangular; venation finely reticulate, largely indistinct on lower surface.

Flowerheads terminal, solitary; sessile or on short peduncles, not exceeding the subtending leaves when in flower; involucre hemispherical, 7–14 mm diameter; involucral bracts bracts in 3 or 4 rows, gradulating green or cream, often mauve at base or margins, stellate hairy, apex ciliate. Ray florets white, 12–22, ligules 5–10 mm long; disc florets yellow, 14–30.

Achenes falttened cylindrical, obscurely ribbed, 2–3 mm long, sericeous; pappus bristles 4–6 mm long, white or cream, in 1 row with an outer row of shorter bristles.

Flowering: Flowers December to January.

Distribution and occurrence: Confined to alpine and higher subalpine areas of south-eastern Australia, occurring from Mount Gingera, Australian Capital Territory, through Kosciuszko National Park in New South Wales, to the Mount Cobberas area, and Bogong High Plains in Victoria, with isolated populations recorded on Mount Buffalo and Mount Hotham.

O. brevipedunculata is readily distinguished from O. phlogopappa by its short peduncles, nearly concolorous sessile leaves that remain moderately stellate-hairy on the adaxial surface. O. brevipedunculata is commonly found growing with O. phlogopappa subsp. flavescens, and in Mount Kosciuszko National Park these two taxa also occur with O. phlogopappa subsp. serrata.
