Characteristics

Prostrate perennial mat-forming herb, profusely branched, densely tufted, branchlets ±10 mm tall, closely leafy. Leaves more or less patent, up to ±5-10 x 0.5 mm, linear, subacute or obtuse, base broad, clasping, margins revolute, both surfaces enveloped in silvery 'tissue-paper-like' indumentum breaking down to wool, rarely loosely woolly, dotted with orange glands. Heads homogamous, cylindric-turbinate, ±5 x 2 mm, solitary to several clustered at the branchlet tips. Involucral bracts in ±6 series, outermost short, pellucid, webbed together and to the surrounding leaves with wool, persistent, inner series subequal, tips opaque white or sometimes pale pink, slightly exceeding the flowers, minutely radiating, soon deciduous. Receptacle with flattened tubercles. Flowers 11-24, yellow, often tipped pink. Achenes 0.75 mm, elliptic, with myxogenic duplex hairs. Pappus bristles many, equalling corolla, scabrid, bases with minute patent cilia not cohering.
