Characteristics

Bushy perennial herb up to ±450 mm high, stems woody, young parts thinly appressed greyish-white woolly, very leafy, primary leaves often subtending very dwarf lateral shoots, making the leaves look fascicled. Leaves mostly 10-40 x 1-5 mm, those on the dwarf shoots sometimes smaller and usually very narrow, linear, linear-lanceolate or oblong-lanceolate, apex acute, base half-clasping, very shortly decurrent, margins more or less revolute, upper surface thinly cobwebby, soon glabrescent, lower surface thinly white tomentose. Heads heterogamous, oblong-campanulate, ±4 x 3 mm, few to many in compact corymbose panicles, terminating the branches. Involucral bracts in 5-6 series, graded, loosely imbricate, tips subacute, opaque white in the inner series, crisped, innermost about equalling the flowers, scarcely radiating. Receptacle shortly honeycombed. Flowers 16-30, 6-13 female, 8-17 homogamous. Achenes 0.75 mm long, with myxogenic duplex hairs. Pappus bristles many, equalling corolla, scabrid, bases cohering by patent cilia.
