Distinguishing Features

  • a tussock-forming, long-lived grass with very fine and highly inrolled leaves (less than 0.5 mm wide).
  • the margins of these leaves are very finely toothed, hence the common name 'serrated tussock'.
  • stems and leaves are upright at first (20-70 cm tall), but become drooping or trailing in nature as they age.
  • the seed-head is an open branched panicle (8-25 cm long) with many flower spikelets that are borne singly.
  • these flower spikelets are elongated in shape (4-9 mm long) and topped with an awn (15-35 mm long).
  • the mature 'seed' has an obscure ring of tiny hairs where the bent and twisted awn attaches to the top of the seed.
