  Upper glume length

  3.5–6.5 mm

  Upper glume relative length

  the upper glume is more than one half as long as the lowest lemma

  Upper glume shape

  the upper glume is widest at or below the middle

  Horizontal rooting stem

  yes

  Lifespan

  the plant lives more than two years

• Leaves

  Basal leaves

  the plant has large or prominent tufts of leaves at the base of the flowering stem

  Leaf auricles

  the leaves do not have auricles

  Leaf basal lobe hairy

  • NA
  • the lobes at the base of the leaf blades are hairless

  Leaf blade base

  the leaf is tapered gradually to the base

  Leaf blade cross-section

  the leaf blade is clearly folded or rolled inwards

  Leaf blade hairs

  • the leaf blade is hairless, but it may have tiny prickles that give it a sand-papery feel
  • the leaf blade is hairy

  Leaf blade texture

  • the leaf blade is rough and sandpapery
  • the leaf blade is smooth, or it may have soft hairs

  Leaf blade width

  0.3–1 mm
