Characteristics

Subshrub up to 1 m tall, stock with vegetative buds, stems many from the base forming rounded clumps, woody, brittle, virgate, forking above into the compound inflorescence, thinly silvery-grey appressed woolly, long red patent glandular hairs as well, closely leafy. Leaves mostly 35-60 x 11-20 mm, 20-40 x 6-15 mm on the inflorescence branches, smaller near the heads, lanceolate, acute to shortly acuminate, base more or less cordate-clasping, lower surface thickly silvery-grey appressed woolly, long red patent glandular hairs as well, upper surface generally appressed woolly, but wool sometimes wanting and then surface merely glandular-setose. Heads heterogamous, (10-)12-13 mm long, (20-)25-28 mm across the radiating bracts, depressed-globose, several in a very open terminal leafy corymbose panicle, or subsolitary on side branches. Involucral bracts in ±9 series, graded, imbricate, inner much exceeding the flowers, glossy, bright yellow, sometimes overlaid pale brown outside. Receptacle shortly honeycombed. Flowers ±750-950, 90-125 female, 640-850 homogamous. Achenes 1 mm long, glabrous. Pappus bristles many, equalling the corolla, tips subplumose, shaft scabrid, bases cohering by patent cilia.
