Stems monopodial, initially leafy, later becoming leafless, with transverse linear leaf-scars following leaf shedding. Leaves alternate or in pseudo-rosette at the apex of stems, simple, sessile or petiolate, with semi-amplexicaul leaf sheath, venation eucamptodromous, margin flat. Capitula fused in a syncephalium (secondary order inflorescence) surrounded by secondary leafy bracts and organized in loose axillary spikes or frequently in a panicle of spikes (rarely a cyme); flowering branch inconspicuously sulcate, flexuose, persistent. Capitula homogamous, discoid, sessile, surrounded by 16 spatulate subinvolucral bracts; phyllaries 56-seriate, apex slightly acute or obtuse, usually shortly mucronate, brown or green, tomentose; receptacle flat, glabrous. Florets bisexual, fertile; corollae actinomorphic, deeply 5-lobed; apical anther appendages lanceolate, acute, anther base sagittate; style shaft glabrous throughout except for pubescence beneath style-arms, style-arms apex acute, pubescent outside, hairs acute, style-base glabrous, lacking basal node. Cypsela cylindrical or obconic, angled, 10-ribbed, carpopodium annuliform, inconspicuous; pappus biseriate, outer series smaller than inner series, paleaceous, persistent, apex acute, erose, base somewhat enlarged, inner series sub-paleacous, caducous or deciduous.</paragraph>
