Characteristics

Dense twiggy shrublet up to 600 mm tall and as much across, or sometimes lax, branches very leafy, both they and the leaves enveloped in closely woven silvery grey indumentum with 'tissue-paper' surface, becoming woolly when old, somewhat viscid. Leaves very variable in size and shape, mostly 6-30 x 1-3(-6) mm, spathulate, narrowly obovate, oblong or linear, often folded lengthwise, apex sub-acute, mucronate, often recurved, base very shortly decurrent. Heads heterogamous, or rarely homogamous on the same plant, cylindric, ±3-4 x 1.5(-2.5) mm, many in clusters crowded in terminal corymbose panicles. Involucral bracts in 4 series, graded, inner equalling flowers, imbricate, ovate-lanceolate, acute, pellucid, glossy, pale lemon-yellow, not radiating. Receptacle smooth. Flowers 3-5(-8), (0-)1(-2) female, 2-4(-7) homogamous, bright yellow. Achenes less than 1 mm long, glabrous. Pappus bristles 2-4, scabrid, nearly equalling corolla, or occasionally wanting. Flowering in any month.
