the nodes in two ranks
Sedges - ----Correct answer---Have solid stems, often
triangular, and leaves in three ranks
Rushes - ----Correct answer---Have solid round stems and
flowers that have two rings of small, brown scale-like
structures similar to petals
What are the aquatic plant growth habits? - ----Correct
answer--- Submersed plants, emersed plants, floating plants
and floating leaf plants
Water fern ( Salvinia minima) - ----Correct answer---
Nonnative floating plant with paired rounded fronds that
have stiff, branched hairs on the upper surface, ¾ inch
across and thin root-like fronds hang beneath
,Giant water fern ( Salvinia molesta) - ----Correct answer---
Nonnative floating plant with thin root-like fronds that hang
beneath the water , hairs on the upper leaf surfaces are fused
at the top compared to being spread open on water fern
Mosquito fern (Azolla caroliniana) - ----Correct answer---native
small flowering plant composed of tiny, closely overlapping
fronds , may be green, brownish-red or red, entire plant is
less than 1/2 inch across and roots hang beneath
Torpedograss (Panicum repens) - ----Correct answer---
invasive emersed, perennial grass, grows extensive rhizomes,
leaves rolled and have fine hairs on upper surface, ring of
fine hairs at the base of leaf, seedheads are branched
sharply upwards and flowers are attached individually along
branches, inflorescence open
Maidencane (Panicum hemitomon) - ----Correct answer---
native emersed perennial grass forms extensive rhizomes,
submersed joints of rhizomes produce feathery roots, leaves
flat, wide and smooth, seedheads narrow, spike-like branches
pressed upwards along central stalk creating tightly enclosed
inflorescence
Para grass (Urochloa mutica) - ----Correct answer---Invasive
forms stems recline and root at the nodes , leaves are flat
and have very fine hairs on upper leaf surface, presence of
dense hairs at nodes and stiff hairs along collar where leaf
sheath joins leaf blades
, Southern watergrass (Luziola fluitans) - ----Correct answer---
Native floating on water surface or emersed , up to 1 ft tall,
on shorelines and moist soils, leaf blades thin and flat , flap
of thin white tissue 1/6in long at top of leaf sheath

- ----Correct answer---native emersed, leafless, spongy,
rounded , 3-angled stems 3-10 ft tall arise from thick
runners, flower cluster occurs at tend of stem 1/2-3 inch,
bristles occur on soft stem bulrush
Slender spike rush or road-grass ( Eleocharis baldwinii) - ----
Correct answer---native has two growth forms, occurs on
moist soils at edge of ponds, erect and leafless stems 1-4 in
tall, stems long and proliferate throughout water column,
leaves occur bladeless sheaths at stem bases, seeds
germinate on mother plant and form daughter plants
Soft rush ( Juncus effusus) - ----Correct answer---native occurs
as shoreline emergent plant, stems are leafless, cylindrical ,
hollow, 2-4ft tall, flowers occur at end of stem and bract ,
basal chestnut colored sheaths at base of each stem
Pickerelweed ( Pontederia cordata) - ----Correct answer---
native emergent shoreline perennial plant with creeping roots,
about 3ft tall reach 6 ft tall, leaves tend to be clusters and
have long stalks, blades narrow or broad heart-shaped, each
stem has leaf and spike numerous violet-blue flowers
