Characteristics

A much-branched, woody, grey or green shrub, usually up to 1 m, occasionally reaching 1.5 m. Branches erect or divaricate, more or less woolly, densely or sparsely leafy. Leaves on main stems in fascicles; subtending leaves patent, slender, subulate, ovate to triangular, straight or very slightly twisted, involute, minute or up to 3 mm long; densely woolly above, cobwebby or almost glabrous below; pungent, acuminate or obtuse, frequently with short mucro which occasionally develops into a spine-like tip; leaves on brachyblasts usually about half the length of the subtending leaves, obtuse or shortly mucronate. Capitula grouped in small clusters in the axils of leaves, terminal on main shoots; sometimes forming a spike-like inflorescence, but more often a panicle. Receptacle stalk-like. Involucral bracts in several rows; outermost small and leaf-like; innermost brown, scarious, sharply acute, a little longer than the corolla. Disc florets bisexual, up to 2 mm long, purple or brown; corolla lobes small erect, triangular. Anthers 5, apical appendages lanceolate, basally tailed. Style branches far exserted from the corolla at maturity. Nectaries absent. Cypselas 5-ribbed, scabrid. Pappus setae 12, slightly joined at the base, as long as or a little shorter than the corolla.
