  • Erect or dwarf shrubs, somewhat ericoid, dense or lax, often glandular
  • Leaves alternate, crowded, linear or linear-lanceolate, sessile, apex mucronate or with curved mucro, with revolute or thickened margins, glandular-hairy or woolly (hair type B)
  • Capitula radiate, solitary, rarely clustered, terminal, sessile or pedunculate
  • Involucre campanulate or turbinate; bracts in 5-7 rows, glandular or hairy on back; stereome undivided
  • Receptacle flat, smooth or sometimes honeycombed, epaleate
  • Ray florets female, in 1 row, deep yellow, fertile; corolla tubular below, with narrowly elliptic 3-toothed lamina
  • Style branches linear, obtuse at apex; stigmatic papillae confined to marginal bands on inner faces and confluent at branch tips
  • Disc florets bisexual, fertile or rarely functionally male; corolla deep yellow, glandular-hairy, cylindric below, abruptly campanulate or more gradually widened above, 5-lobed
  • Anthers ecalcarate, caudate; with deltoid or oblong-obtuse apical appendage; endothecial tissue polarised
  • Style branches (when fertile) oblong, slightly branched at obtuse tips, minute pollen-sweeping papillae on outer faces; stigmatic bands marginal on inner surfaces, not meeting at tip
  • Cypselas cylindric or fusiform, 10-15-ribbed, glabrous or hairy
