Habit	Suberect or decumbent, spreading, or mat-forming soft shrubs; shoots slender, purple, subherbaceous, eventually becoming woody, hispidulous, often nearly leafless toward apex when flowering, lower portions usually enveloped by dead leaves.
Leaves	Leaves persistent, alternate, erect and rather densely tufted to widely spaced and spreading or even reflexed, narrowly linear to linear-elliptic or linear-oblong to linear-lanceolate, 1-9 cm long, 0.8-8 mm wide, 1-nerved or very rarely in the broadest forms 3-nerved, both surfaces usually scabrous or occasionally smooth, margins entire or more often remotely 1-3(4)-denticulate apically, scabrid-ciliate or spinulose-ciliate, usually revolute, apex rather abruptly to attenuately acute, base usually truncate, sessile.
Flowers	Heads usually 6-100(-140), usually cymosely arranged in strongly exserted, compound, corymbose inflorescences usually 2-18 cm long, 2-22 cm wide, peduncles purplish, hispidulous, ultimate ones very slender, usually 2-15(-30) mm long; receptacle flat, false involucre consisting of a single series of 5-6(-8) peripheral, connate (often separating upon drying) receptacular bracts usually 5-6.5 mm long, purplish or purple-veined, hispidulous; florets 5-7(-9) per head, corollas white, usually 3.5-4 mm long, glabrous, eglandular; pappus of 15-22 very narrowly linear, ascending-setose bristles 3-5 mm long.
