Description:

  • Perennial herbs or shrublets, sprawling, ascending or erect, stout, closely leafy throughout
  • Leaves alternate, rigid, ascending, erect or appressed, imbricate, subulate to linear-lanceolate, often rounded abaxially, often long on vegetative shoots, short on flowering shoots, often bract-tipped below involucre, base broad, clasping, margins entire, strongly involute and hiding upper surface in long leaves, flat in short leaves, white-tomentose above (hair type B), glabrous and shining below
  • Capitula discoid or disciform, broadly campanulate, large, often solitary at branch tips, or rarely 2 to several
  • Involucral bracts in many rows, loosely imbricate, radiating, inner much exceeding florets, white, pink or yellow, outer sometimes pale dark brown; stereome divided
  • Receptacle flat, epaleate, fimbrilliferous
  • Flowers ± 85-315, 0-19 female; corolla of female flowers narrowly tubular or filiform; of bisexual flowers campanulate above, 5-lobed; all flowers glandular-hairy on backs of lobes
  • Anthers ecalcarate, caudate, tails ± equalling filament collar; with lanceolate apical appendage; endothecial tissue polarised; staminodes often present in female flowers
  • Style branches truncate and penicillate with obtuse sweeping hairs
  • Cypselas either terete with myxogenic duplex hairs, or (E. pinifolia) flattened, winged, glabrous
  • Pappus bristles shortly plumose above, barbellate below, fused at base in smooth ring, also cohering by small patent cilia
