Cynodon dactylon — Bermuda grass

Characteristics

• Flowers

  Anther number

  3

  Awn on glume

  the glume has no awn

  Floret lower bract texture

  the lemma is thin and flexible

  Glume relative length

  neither glume is quite as long as all of the florets

  Glume veins

  • 1
  • 3

  Inflorescence axis orientation

  • the inflorescence axis is arched or curved outward
  • the inflorescence axis is straight

  Inflorescence branches

  the flowers are attached to branches rather than to the main axis of the inflorescence

  Inflorescence length

  Up to 60 mm

  Inflorescence type (general)

  the spikelets are borne on stalks or on branches

  Inflorescence type (specific)

  the inflorescence is branched and the branches all grow from the same side of the plant and look like spikes

  Lemma awn base

  NA

  Lemma awn length

  0 mm

  Lemma awn number

  the lemma has no awn

  Lemma cross-section

  the lemma is V-shaped if you cut across the midpoint

  Lemma surface

  the surface of the lemma is relatively smooth (not counting any longitudinal veins or hairs)

  Lemma tip

  the lemma tip is a simple point, with or without an awn (long narrow extension ending in a point)

  Lemma vein number

  • 1
  • 3

  One or more florets

  there is one floret per spikelet

  Palea relative length

  palea is one half to fully as long as lemma

  Spikelet length

  2–3.2 mm

  Spikelets spiny

  the spikelets do not appear spiny

• Growth form

  Horizontal rooting stem

  yes

  Rhizomes

  • no
  • yes

• Leaves

  Leaf auricles

  the leaves do not have auricles

  Leaf blade width

  1–5 mm

  Leaf ligule length

  0.2–0.6 mm

  Leaf ligule type

  the leaf ligule is in the form of a membrane with fine hairs

  Leaf sheath closed around stem

  the margins of the leaf sheath are overlapping and not fused together except in the basal half (or less)

  Leaf sheath hairs

  • there are hairs on the surface of the leaf sheath
  • there are no hairs on the surface of the leaf sheath

• Place

  Habitat

  terrestrial

  New England state

  • Connecticut
  • Massachusetts

  Specific habitat

  • man-made or disturbed habitats
  • meadows or fields

• Stem, shoot, branch

  Stem spacing

  • the stems grow close together in compact clusters or tufts
  • the stems grow singly or a few together (they may form diffuse colonies)

Wetland status

Usually occurs in non-wetlands, but occasionally in wetlands. (Wetland indicator code: FACU)
