  • Shrubs or subshrubs
  • Leaves alternate, closely set, linear-filiform, ericoid, entire or lobed-pinnatipartite, sometimes with additional lobes from leaf base ('pseudostipules'), subterete-flattened, herbaceous-coriaceous, pubescent-glabrescent, with impressed glands in hollows or furrows
  • Capitula radiate, solitary, terminal, pedunculate
  • Involucre hemispherical-cup-shaped; involucral bracts imbricate, ovate-oblong-lanceolate or spathulate, coriaceous with brownish membranous margins and tips, glandular and floccose-woolly or glabrescent
  • Receptacle convex-hemispherical or subconical, epaleate
  • Ray florets female, fertile, 9-21, white-pinkish; tube somewhat compressed, glandular; lamina 4(5)-veined, apically 3-fid
  • Style branches oblong, truncate
  • Disc florets bisexual, many, yellow; corolla regular, with somewhat spongy glandular tube and narrow 5-lobed limb
  • Anthers ecalcarate and ecaudate, with ovate-oblong, obtuse-subtruncate apical appendage; filament collar oblong, of subequal cells
  • Style fertile with truncate branches; base not much swollen, partly immersed in short and sometimes indistinct nectary
  • Cypselas oblong, terete or angular, usually 5-ribbed, glandular with broad sessile glands, with myxogenic cell layers, especially abaxially
