    Inflorescence arrangement
    the plant has two types of spikelets with different reproductive structures
    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
    • there are no branch points between the base of the inflorescence axis and the flowers, or they are not obvious
    Inflorescence type (general)
    • the inflorescence is a spike, or is spike-like, lacking obvious branches
    • the spikelets are borne on stalks or on branches
    Inflorescence type (specific)
    the inflorescence has pairs (or trios) of spikelets, but with one always either missing a stalk or on a shorter stalk than the other
    Lemma awn base
    • NA
    • the awn is attached right at the tip of the lemma
    Lemma awn length
    0–20 mm
    Lemma awn number
    • the lemma has no awn
    • the lemma has one awn on it
    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 tip
    the lemma tip is split into two or more points
    Lemma vein number
    • 1
    • 3
    One or more florets
    there is one floret per spikelet
    Spikelet axis tip
    there is no extension of the spikelet axis beyond the tip of the spikelet
    Spikelet disintegration
    the spikelet breaks off below the glumes
    Spikelet length
    1.5–10 mm
    Spikelets spiny
    the spikelets do not appear spiny

    Leaf auricles
    the leaves do not have auricles
    Leaf blade width
    3.5–6.5 mm
    Leaf ligule length
    1.5–2 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
    terrestrial
    New England state
    Connecticut
    Specific habitat
    • dunes
    • sea beaches
  • Stem, shoot, branch
    Stem orientation
    the stems trail at the base, but turn upwards at the tips
    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)
