Muhlenbergia uniflora — bog muhly

Characteristics

• Flowers

  Anther length

  0.6–0.9 mm

  Anther number

  3

  Awn on glume

  the glume has an 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 arrangement

  the spikelets are uniform

  Inflorescence axis orientation

  the inflorescence axis is straight

  Inflorescence branches

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

  Inflorescence crowding

  the panicle is somewhat to very spread out, with clearly-evident branches

  Inflorescence length

  20–200 mm

  Inflorescence type (general)

  the spikelets are borne on stalks or on branches

  Inflorescence type (specific)

  the inflorescence is branched, and the branches do NOT both 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 base hairs

  the lemma is hairless or feels just a tiny bit rough at the base

  Lemma cross-section

  the lemma is flat or rounded if you cut across the midpoint

  Lemma surface

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

  Lemma vein number

  3

  One or more florets

  there is one floret per spikelet

  Palea relative length

  • palea is longer than lemma
  • palea is one half to fully as long as lemma

  Spikelet axis tip

  there is no extension of the spikelet axis beyond the tip of the spikelet

  Spikelet length

  1.3–2.1 mm

  Spikelet pedicel

  the spikelets have pedicels

  Spikelet pedicel length

  0.2–7 mm

  Spikelets spiny

  the spikelets do not appear spiny

  Upper glume shape

  the upper glume is widest at or below the middle

• Leaves

  Leaf auricles

  the leaves do not have auricles

  Leaf blade width

  0.8–2 mm

  Leaf ligule length

  0.5–1.5 mm

  Leaf ligule type

  the leaf ligule is in the form of a membrane

  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

  wetlands

  New England state

  • Connecticut
  • Maine
  • Massachusetts
  • New Hampshire
  • Rhode Island
  • Vermont

  Specific habitat

  • bogs
  • fens (calcium-rich wetlands)
  • man-made or disturbed habitats
  • meadows or fields
  • shores of rivers or lakes

• Stem, shoot, branch

  Stem spacing

  the stems grow close together in compact clusters or tufts

Wetland status

Occurs only in wetlands. (Wetland indicator code: OBL)
