Poaceae - Chloridoideae - Eragrostideae - Uniolinae - Fingerhuthia Nees

Description:

  • Perennial, rarely annual in desert areas, tufted, rhizomatous
  • Leaf blade long-linear, expanded or folded; ligule a fringe of long hairs
  • Inflorescence a compact, cylindric, spike-like panicle, usually oblong in outline, central axis terete; spikelets solitary, pedicelled, pedicels remaining after spikelets have fallen
  • Spikelet 4-6 mm long, strongly laterally compressed, disarticulating with glumes; glumes ± equal, longer than spikelet, similar, membranous, lanceolate, 1-nerved, sparsely to densely hairy on keels, shortly awned or mucronate
  • Florets 2-4; lowest floret bisexual; remaining florets male, sterile or reduced; lower lemma lanceolate or linear-oblong, similar to firmer in texture to glumes, membranous, glabrous or hairy, (3)-5-7-nerved, keeled, entire, apex rounded or acuminate, shortly awned or mucronate; uppermost lemma smaller; palea slightly shorter than lemma, ovate-lanceolate, membranous
  • Lodicules 2, cuneate
  • Stamens 3
  • Ovary slightly constricted below apex, glabrous; styles distinct, finely plumose
  • Caryopsis ellipsoid
  • x = 10 (polyploidy)
