Asteraceae - Gnaphalieae - Anderbergia B.Nord.

Description:

  • Erect or diffuse shrublets without stolons, with greyish whitish tomentum
  • Leaves alternate, sessile, simple, entire, tomentose, eglandular, with revolute margins
  • Capitula disciform, small, in terminal dense corymbs
  • Involucral bracts dimorphic, ± tomentose, with undivided stereome; outer involucral bracts narrowly linear to oblong or spathulate with membranous brown distal portion; inner involucral bracts unguiculate with linear-oblong, ± tomentose claw and white opaque, glabrous, petaloid apical portion
  • Receptacle epaleate
  • Female florets (0)1 or 2; corolla white or yellowish, shortly lobed
  • Style bifurcate
  • Cypsela ellipsoid-oblong, glabrous or shortly hirsute with papilliform nonmyxogenic twin hairs, rarely also sparsely setose with longer narrower hairs
  • Ovary wall crystals prismatic (rectangular, hexa- or octagonal), homomorphic or heteromorphic
  • Pappus bristles uniseriate, basally shortly connate or nearly discrete, without patent cilia, barbellate throughout with usually short acute to obtuse teeth
  • Functionally male florets few (3-6); corolla white or yellow, tubular below, with campanulate 5-lobed limb; lobes erect to spreading, with marginal veins reaching lobe apex
  • Anthers with basal tails and apical flat ± ovate-triangular appendage; endothecium polarised; filament collar elongate, straight
  • Style sterile, simple with subclavate or truncate tip, sometimes minutely bifid, with obtuse, short sweeping hairs; stylophore distinct, broader than style
  • Ovary aborted, glabrous, 2-veined
  • Pappus bristles uniseriate, basally shortly connate or almost discrete, without patent cilia, barbellate throughout with acute to obtuse or subclavate teeth
