Characteristics

A well-branched shrub, branches either prostrate or erect to ±600 mm, branchlets silky grey-felted, closely leafy. Leaves erect or spreading, imbricate, ±5-20 x 1-2(-3) mm, linear, acute or subacute, mucronate, slightly hooked, base half-clasping, slightly decurrent, margins revolute, both surfaces enveloped in silvery tissue-paper-like indumentum that hides dense coarse hairs below. Heads homogamous, campanulate, 4-6(-7) x 3-6(-7) mm, solitary or 2-3-±20 in very compact corymbose clusters, often webbed to surrounding reduced leaves, at the branchlet tips. Involucral bracts in 4-5 series, outermost shorter, inner subequal, loosely imbricate, slightly exceeding flowers, scarcely radiating, tips obtuse or acute, tawny, glossy. Receptacle with fimbrils equalling the ovaries. Flowers 15-44. Achenes not seen, ovaries, glabrous. Pappus bristles many, scabrid, about equalling corolla, bases cohering by patent cilia. Flowers can be found in any month, but the main season seems to be between April and September.
