Plants
• Agrostis gigantea; Synonyms:
Agrostis alba; Red Top; Introduced
(Europe); Very common in forests, fields, prairies, roadsides
and moist disturbed areas throughout the Refuge. The closely related A.
stolonifera (Creeping Bent Grass), not yet reported, should be
looked for in the Refuge. It can be identified by the presence of
stolons (instead of rhizomes) and a narrow (rather than spreading)
inflorescence. Photos

Plants
• Andropogon gerardii; Big Bluestem;
Native; This symbol of the tallgrass prairie is locally common in fields
and prairies throughout the Refuge. An impressive, stately grass. Photos
Phytoimages; USDA
Plants
• Andropogon gyrans; Synonyms: Andropogon elliotii;
Elliott's Broom Sedge; Native; Locally common in roadsides and fields,
e.g., along Stringtown Road. The plant can often be recognized from a
distance by its rusty-red color. Photos
Phytoimages; USDA
Plants
• Andropogon virginicus; Broom-Sedge; Native; Common in
roadsides and fields throughout the Refuge. This plant has naturalized
in Australia. Its common name is a misnomer, as the plant is not a
sedge. A familiar sight in late fall. Photos
Phytoimages; USDA
Plants
• Aristida dichotoma; Churchmouse Three-Awn; Native;
Uncommon. It occurs on glades along the east side of Devil's Kitchen
Lake. The plant is also called "Poverty Grass." Churchmice are said to
be very poor. Hence the common name. Photos
Phytoimages; USDA
Plants
• Aristida longespica; Slimspike Three-Awn; Native;
Occasional to rare. It occurs at the southern boundary of the Refuge,
e.g. along the Touch of Nature line. Photos
Phytoimages; USDA
Plants
• Aristida oligantha; Plains Three-awn; Native; Locally
common in dry, disturbed areas and glades. Can be recognized by its very
long awns (up to 7 cm long). A large patch of this species grows between
the parking area and the shore near the Spillway Crab Orchard Lake boat
ramp. Photos
Phytoimages; USDA
Plants
• Arundinaria gigantea; Giant Cane; Native; Uncommon in
moist areas and low ground. A tall plant -- up to 5 meter or more.
It is actually a kind of bamboo. Photos
Phytoimages; USDA
Plants
• Avena sativa; Oats; Introduced (Eurasia); An
uncommon weedy species. In disturbed areas, e.g., along the parking lot
at Wolf Creek Causeway. Jones (2005) and Mohlenbrock (2014)
recognize A. sativa as a distinct species. Yatskievych (1999)
considers it to be a variety of A. fatua. Photos
Phytoimages; USDA
Plants
• Brachyelytrum erectum; Long-awned Wood
Grass; Native; Uncommon. This interesting lanky grass occurs in upland
forests. It can be found along Rocky Bluff Trail as well as in the
Prison RNA. Photos
Phytoimages; USDA
Plants
• Bromus arvensis; Field Brome
(Chess); Introduced (Europe); CCP and Ulaszek (1988) rate this species
as locally common on a disturbed sandstone glade. Mohlenbrock (2014)
reports it as "adventive in waste ground, not common but scattered in
Illinois." Yatskievych (1999) excludes this taxon from the Missouri
flora: apparently the only documentation of this plant in Missouri (at
St. Louis in 1983) turned out to be misidentified B. japonicus.
Jones (2005) does not mention the plant at all. Bromus arvensis
is very difficult to distinguish from either B. japonicus or B.
racemosus, both common, even abundant grasses. Hence easily
overlooked. Photos
Phytoimages; USDA
Plants
• Bromus commutatus; Hairy Chess,
Meadow Brome; Introduced (Europe); Common in roadsides and fields. This
species is almost identical to B. racemosus. The lemmas
of mature spikelets of B. commutatus and the branches of
the inflorescence are longer than those of B. racemosus. Photos
Phytoimages; USDA
Plants
• Bromus inermis; Smooth Brome;
Introduced (Europe); Uncommon in roadsides, fields and disturbed areas.
It is an abundant grass to the north of us. Photos
Phytoimages; USDA
Plants
• Bromus japonicus; Japanese Brome;
Introduced (Eurasia); A very common weedy grass of waste places,
disturbed areas, and roadsides. The curved or twisted awns separate this
taxon from B. commutatus and B. racemosus. Photos
Phytoimages; USDA
Plants
• Bromus pubescens; Synonyms:
Bromus purgans; Woodland Brome; Native; This aptly named, tall, graceful
grass is common to abundant in woodlands throughout the Refuge. A
lovely sight in the woods. Photos
Phytoimages; USDA
Plants
• Bromus racemosus; Bald Brome;
Introduced (Europe); Common to abundant in roadsides, fields, and
disturbed areas. See B. arvensis and B. commutatus
above. Photos
Phytoimages; USDA
Plants
• Bromus sterilis; Barren Brome
Grass; Introduced (Europe); Uncommon. A sizable population can be found
along Tacoma Lake Road between Rocky Bluff and Devil's Kitchen dam. It
appears to be a recent invasive, not listed by Ulaszek (1988) or
CCP. Photos
Phytoimages; USDA
Plants
• Bromus tectorum; Downy Cheat
Grass; Introduced (Europe); Probably our most abundant Brome, flowering
along roadsides and waste places. The spikelets are crowded and
long-awned, giving the plant a bushy appearance. Though weedy, it is, on
closer look, a pretty grass. Photos
Phytoimages; USDA
Plants
• Chasmanthium latifolium; Synonyms:
Uniola
latifolium; River Oats; Native; This plant is very common in woodsy
areas throughout the Refuge. It is listed by Ulaszek (1988), but not in
CCP. The flat, drooping spikelets help turn this beautiful plant into a
familiar sight. Photos
Phytoimages; USDA
Plants
• Cinna arundinacea; Stout Wood
Reed; Native; Another impressive, tall and stately woodland plant,
locally common in forests and moist shaded areas throughout the
Refuge. Photos
Phytoimages; USDA
Plants
• Cynodon dactylon; Bermuda Grass;
Introduced (Europe or Africa); A low-growing mat-forming plant,
occupying large areas in the Prairie Creek Recreation Area, south of Hwy
13. Mohlenbrock (2014) considers it occasional in the southern half of
Illinois. Photos
Phytoimages; USDA
Plants
• Dactylis glomerata; Orchard Grass;
Introduced (Europe); Common. Originally planted as a pasture grass, it
has spread into fields, roadsides, and disturbed areas throughout the
Refuge. Photos
Phytoimages; USDA
Plants
• Danthonia spicata; Poverty Oat
Grass; Native; Locally common in wooded areas and shaded roadsides. The
leaves at the base of this plant are curled. Photos
Phytoimages; USDA
Plants
• Dichanthelium acuminatum; Rosette
Grass
/ Hairy Panic Grass; Native; Common at forest edges, moist areas, fields
and disturbed areas. Abundant in the woods surrounding Devil's Kitchen
Lake. A widespread grass in both North and South America. It is
variable: numerous varieties have been named. Photos
Phytoimages; USDA
Plants
• Dichanthelium boscii; Large-fruited
Panic Grass; Native; Very common at forest edges and in forests. Also in
Rocky Bluff area. Can be recognized by its relatively broad leaves and
hairy nodes. Photos
Phytoimages; USDA
Plants
• Dichanthelium clandestinum; Deer-Tongue's
Grass;
Native; Locally common in moist areas in forest. Along the creek near
entrance to Rocky Bluff Trail. It also has broad leaves, but the nodes
are not hairy. It is a much more robust plant than D. boscii. Photos
Phytoimages; USDA
Plants
• Dichanthelium commutatum; Broad-leaved
Panic
Grass; Native; Uncommon. Can be found in woods near the entrance to
Rocky Bluff Trail. This grass resembles D. clandestinum, but
the spikelets are shorter and the leaf sheaths are not hairy. Photos
Phytoimages; USDA
Plants
• Dichanthelium depauperatum; Synonyms:
Panicum
depauperatum; Starved Panic Grass; Native; Herbarium specimen by Ellis
& DeFilippi 1960, in the dam area of Devil's Kitchen lake, accession
no. 39350. Photos
Phytoimages; USDA
Plants
• Dichanthelium dichotomum; Forking
Panic
Grass; Native; Ulaszek (1988) considers the presence of this plant to be
occasional. It is very common along forest edges and in forests
throughout Refuge. Botanists recognize a half dozen or more
varieties. Photos
Phytoimages; USDA
Plants
• Dichanthelium laxiflorum; Loose-flowered
Panic
Grass; Native; Common at forest edges , easily found, e.g., in the woods
on the west side of Devil's Kitchen Lake. Photos
Phytoimages; USDA
Plants
• Dichanthelium linearifolium; Narrow-leaved
Panic
Grass; Native; Ulaszek (1988) reports this plant as uncommon, occurring
in successional fields and on sandstone glades. Mohlenbrock (2014)
considers it occasional in dry woods throughout the state. I have not
yet seen it in the Refuge. Photos
Phytoimages; USDA
Plants
• Dichanthelium microcarpon; Small-fruited
Panic
Grass; Native; ]: Occasional in dry-mesic upland forest. It occurs,
e.g., along Grassy Creek at Rocky Bluff Trail. Jones (2005)
and Yatskievych (1999) treat this taxon as a variety of D.
dichotomum. Photos
Phytoimages; USDA
Plants
• Dichanthelium polyanthes; Many-flowered
Panic
Grass; Native; ]: Locally common in wooded areas. Can be found along
Grassy Creek at Rocky Bluff Trail and in woods around Little Grassy
Lake. Mohlenbrock (2014) and Jones (2005) recognize this taxon as a
distinct species. Yatskievych (1999) considers it a variety of D.
sphaerocarpon (see below). Photos
Phytoimages; USDA
Plants
• Dichanthelium scoparium; Velvety
Panic
Grass; Native; Rare. It occurs at the southern edge of the fields across
from Harmony Trail. Ulaszek (1988) does not list it. This interesting
grass can be easily identified by its hairy stems and the presence of a
sticky band below each node of the stem. Photos
Phytoimages; USDA
Plants
• Dichanthelium sphaerocarpon; Round-fruited
Panic
Grass; Native; Occasional, scattered on wooded slopes in dry upland
forest along the west side of Devil's Kitchen Lake. Photos

• Digitaria sanguinalis; Hairy Crab
Grass; Introduced (Eurasia); Common in lawns, disturbed areas, roadsides
and fields. Photos
Phytoimages; USDA
Plants
• Echinochloa colonum; Synonyms:
Echinochloa colona; Jungle Rice; Introduced (Eurasia); Occasional in
dry, disturbed areas and waste ground. Occurs, e.g., at the Wolf Creek
Causeway parking area. Photos
Phytoimages; USDA
Plants
• Echinochloa crus-galli; Barnyard
Grass;
Introduced (Eurasia); Its status in the Refuge is unclear, due to its
similarity to our native E. muricata (see below). It occurs
along shores of Little Grassy Lake. Also at observation deck at west end
of Wolf Creek Causeway. Apparently this species is infrequent in
forested areas. It can be identified by the absence of "puscular bases"
(blisterlike bumps at the base) of the hairs of the spikelet. Photos
Phytoimages; USDA
Plants
• Echinochloa muricata; Rough Barnyard
Grass; Native; This is the common Barnyard Grass in the Refuge. Occurs
in a variety of habitat: woods, roadsides, fields, disturbed areas, an
on the shores of creeks and lakes. Photos
Phytoimages; USDA
Plants
• Eleusine indica; Goose Grass;
Introduced (Eurasia); ]: Common in disturbed areas and waste ground,
roadsides and fields throughout the Refuge. Introduced from Asia or
Africa. The spikes of this generally low-growing grass look zippered Photos

• Elymus villosus; Hairy Wild Rye;
Native; Common, mostly in wooded areas. Throughout the Refuge. Photos
Phytoimages; USDA
Plants
• Elymus virginicus; Virginia Wild
Rye; Native; Common in woods, thickets, and along creek banks and lake
shores. This plant resembles E. villosus, but its spikes are
erect; those of E. villosus are nodding. Photos
Phytoimages; USDA
Plants
• Eragrostis capillaris; Lace Grass;
Native; Occasional in dry soil in wooded areas. Occurs e.g., on
peninsula at north end of Devil's Kitchen Lake. A delicate, wispy plant.
Photos
Phytoimages; USDA

• Eragrostis cilianensis; Stinking
Love
Grass; Introduced (Eurasia); Uncommon in waste ground, disturbed areas,
lawns, roadsides, even cracks in sidewalks. It is a glandular plant,
exuding an unpleasant odor. Photos
Phytoimages; USDA
Plants
• Eragrostis frankii; Sandbar Love
Grass; Native; Another wispy love grass, occasional in moist, sandy
areas and roadsides. Occurs, e.g., along dirt roads leading to Crab
Orchard Lake. Photos
Phytoimages; USDA
Plants
• Eragrostis hypnoides; Pony Grass,
Creeping Love Grass; Native; Occasional in muddy areas. Occurs along
shore of Little Grassy Lake near boat landing by dam. It forms mats by
rooting at the nodes. Photos
Phytoimages; USDA

• Eragrostis pectinacea; Carolina Love
Grass; Native; Common in disturbed areas throughout the Refuge. Photos
Phytoimages; USDA
Plants
• Eragrostis pilosa; India Love
Grass; Introduced (Eurasia); Occasional in sandy roadside areas, e.g.,
at end of road to South Grassy Bay off Spillway Road. It is very similar
to E. frankii, differing in the size of the glumes. Photos
Phytoimages; USDA
Plants
• Eragrostis spectabilis; Purple
Love
Grass; Native; Common in fields, along roadsides and disturbed areas.
Often recognized from a distance by its pale purplish color, especially
when growing in masses. After it matures, the plant often becomes a
tumble weed. Photos
Phytoimages; USDA
Plants
• Saccharum
alopecuroides; Synonyms:
Erianthus alopecuroides; Silver Plume Grass; Native;
A tall handsome grass, often exceeding 3 meters in height, with large
silvery plumes. Occasional. Scattered along edges of woodland in both
Crab Orchard and Devil's Kitchen Lake areas. Photos
Phytoimages; USDA
Plants
• Festuca subverticillata; Synonyms: Festuca obtusa; Nodding
Fescue; Native; This elegant fescue is locally common in wooded areas.
Plentiful along Rocky Bluff Trail. A very similar species, F.
paradoxa, is to be looked for in the Refuge. Its spikelets
strongly overlap, whereas those of F. subverticillata are
widely spaced. Photos
Phytoimages; USDA
Plants
• Festuca trachyphylla; Sheep Fescue; Introduced (Europe); Photos
Phytoimages; USDA
Plants
• Glyceria striata; Fowl Manna Grass; Native; A
beautiful, tall, yet delicate grass with multiple inflorescence branches

• Hordeum pusillum; Little Barley; Native; Locally
common along roadsides and in disturbed ground and fallow fields
throughout the Refuge. Native. It is actually a southern plant, reaching
as far north as Illinois. Photos
Phytoimages; USDA
Plants
• Hordeum vulgare; Barley;
Introduced (Asia); Occasionally escaped from fields along west side of
Hwy 148. Photos
Phytoimages; USDA
Plants
• Leersia oryzoides; Rice Cutgrass;
Native; Locally common along marshy lake and creek shores. This tall
aptly-named grass blooms in the fall, its light green color making it a
conspicuous presence in wet areas. The leaves are minutely spiny and
saw-toothed, giving rise to the saying: Nothing cuts like Leersia! A
truth readily acknowledged when walking through a patch of this grass! Photos
Phytoimages; USDA
Plants
• Leersia virginica; White Cutgrass;
Native; Locally common in woods and shaded moist areas. This plant
can be confused with the invasive Stilt Grass (Microstegium vimineum
-- see below). Photos
Phytoimages; USDA
Plants
• Leptochloa fascicularis; Synonyms:
Leptochloa
fusca; Salt Meadow Grass; Native; Rare. Along Campground Road north of
Giant City Park. Some botanists consider L. fascicularis a
subspecies of L. fusca, others do just the reverse. I follow
Mohlenbrock (2014). Photos
Phytoimages; USDA
Plants
• Leptochloa panicea; Synonym:
Leptochloa attenuata; Red Sprangletop; Native; Rare. A beautiful grass.
Occurs in fields along Stringtown Road. Photos
Phytoimages; USDA

• Leptochloa panicoides; Synonyms:
Diplachne
panicoides; Amazon Sprangletop; Native; Rare. Along shore of Crab
Orchard Lake east of Hwy 148 at north end of Causeway. Photos
Phytoimages; USDA
Plants
• Lolium multiflorum; Italian Rye
Grass; Introduced (Europe); A common weed in fields, roadsides,
disturbed areas, waste ground, around parking areas. Yatskievych (1999)
and Jones (2005) consider this species to be a variety of L.
perenne (see below). The two taxa seem quite distinct: L.
multiflorum is an annual, with spikelets 10-20-flowered, and more
robust than L. perenne which is a perennial, with spikelets
6-10-flowered. Photos
Phytoimages; USDA
Plants
• Lolium perenne; English Rye
Grass; Introduced (Europe); A common weed in fields, roadsides,
disturbed areas, waste ground, around parking areas. See L. multiflorum
above. Photos
Phytoimages; USDA
Plants
• Melica nitens; Three-flowered
Melic Grass; Native; Occasional. Rocky woods and sandstone glades. I
have not yet located this neat plant in the Refuge. Photos
Phytoimages; USDA
Plants
• Microstegium vimineum; Stilt Grass;
Introduced (Asia); This foreign invader is rapidly becoming a serious
problem in the Refuge. Jones (2005) reports this species as abundant in
Kentucky, while Mohlenbrock (2014) still listed it as occasional in
southern Illinois. In the Refuge it is locally abundant in woods, shaded
places and near weedy shores. Extensive patches occur along the
River-to-River Trail. At Rocky Bluff, Stilt Grass is poised to choke out
many of the beautiful native plants that make the area a paradise for
nature photographers. Photos
Phytoimages; USDA
Plants
• Muhlenbergia bushii; Nodding Muhly;
Native; Ulaszek (1988) reports this grass as rare in floodplain forest.
Mohlenbrock (2014) describes the species as "not common," restricted to
the southern 2/3 of Illinois. It is on the endangered list in Kentucky.
It appears to be more common in Missouri. I have not seen it in the
Refuge. Photos
Phytoimages; USDA
Plants
• Muhlenbergia frondosa; Common Satin
Grass; Native; Ulaszek (1988) reports this taxon as locally common in
fields, thickets, and margins of Devil's Kitchen Lake. A common and
widespread plant, no doubt by oversight not yet observed in the Refuge.
Photos
Phytoimages; USDA
Plants
• Muhlenbergia schreberi; Nimblewill;
Native;
Locally common is shaded, weedy sites in woods and disturbed soil. In
the fall this plant, rooting at the nodes, tends to turn into a
sprawling mass of green. Its common name, originally spelled "nimble
Will," refers to the speed with which the grass was thought to overtake
new areas. Photos
Phytoimages; USDA
Plants
• Muhlenbergia sobolifera; Rock
Satin
Grass; Native; A dainty grass, locally common in woods and shaded
places. Other similar Muhlenbergia species, such as M. mexicana and M.
sylvatica, should be looked for in the Refuge woodlands. Photos
Phytoimages; USDA
Plants
• Panicum anceps; Synonyms:
Coleataenia anceps; Beaked Panic Grass; Native; A very common grass,
abundant in fields, moist areas in woods and ditches throughout the
Refuge. Easily identified by its sickle-shaped spikelets. Mohlenbrock
(2014) assigns this plant to a distinct genus Coleataenia
(One-sided Panicum), in agreement with the Integrated Taxonomic
Information System (ITIS). The genus differs from Panicum in
that the panicle branches are one-sided and the spikelets are on
pedicels less than 1 mm long. Photos
Phytoimages; USDA
Plants
• Panicum capillare; Witch Grass;
Native; Status unclear because of its similarity to P. gattingeri and
P. philadelphicum (see below). Of these three, Ulaszek (1988)
and CCP lists only P. gattingeri. Plants I examined near the
boat landing on the west side of Devil's Kitchen Lake off Tacoma Lake
Road near the dam and around Little Grassy Lake appeared to check out as
P. capillare. This species, a pretty grass, is reported to be a
common widespread weed. Photos
Phytoimages; USDA
Plants
• Panicum dichotomiflorum; Fall Panicum;
Native; Uncommon. Ulaszek (1988) reports this grass as locally common
along roadsides, waste ground, and margins of ponds and Devil's Kitchen
Lake. In habit resembles P. virgatum, but can be identified by
its more modest appearance, smaller spikelets, and the clincher: a very
short, rounded lower glume. Photos
Phytoimages; USDA
Plants
• Panicum flexile; Slender Panic
Grass; Native; Uncommon along roadsides and forest edges around Devil's
Kitchen Lake. Its narrow spikelets are longer compared to those of
similar Panicum species. Photos
Phytoimages; USDA
Plants
• Panicum gattingeri; Gattinger's
Panic Grass; Native; Status unclear. Ulaszek (1988) reports it as
locally abundant in a sandstone glade. This plant appears to be common
near Devil's Kitchen dam and at the north end of Little Grassy Lake.
This grass is robust -- up to a meter tall. Yatskievych (1999) considers
it a synonym for P. philadelphicum. Jones (2005) lists it as a
subspecies of P. philadelphicum. This seems problematic, as P.
philadelphicum is normally a much smaller plant. Photos
Phytoimages; USDA
Plants
• Panicum philadelphicum; Philadelphia
Witchgrass;
Native; Uncommon. Plants observed along Tacoma Lake Road appeared to
match the manuals' descriptions. Photos
Phytoimages; USDA

• Panicum rigidulum; Synonyms:
Coleataenia rigidulum; Munro Grass, Redtop Panic Grass; Native; Locally
abundant in moist areas and margins of ponds and lakes. For the name
change, see Panicum anceps above. Photos
Phytoimages; USDA
Plants
• Panicum virgatum; Switch Grass;
Native; We can find it in areas along the northeast shore of Little
Grassy Lake. A tall (up to 3 meter), sturdy, yet graceful grass. Photos
Phytoimages; USDA
Plants
• Paspalum dissectum; Mudbank Bead
Grass; Native; Ulaszek (1988) found one colony of this rare plant in
shallow water and margin of an artifical pond. It is a southeastern,
semi-aquatic species. Panicum dissectum is listed as
endangered on the 2011 Illinois Endangered Species Protection Board
Checklist. Photos
Phytoimages; USDA

• Paspalum laeve; Smooth Lens
Grass, Field Paspalum; Native; Our most abundant Paspalum. It occurs in
lawns, fields, roadsides, ditches. The spikelets are attached singly to
the rachis. Photos
Phytoimages; USDA
Plants
• Paspalum pubiflorum; Hairyseed Bead
Grass; Native; Another very common Paspalum, found along roads
and in moist areas throughout the Refuge. Spikelets are attached as
pairs and over 3 mm long. Photos
Phytoimages; USDA
Plants
• Paspalum setaceum; Synonyms:
Paspalum ciliatifolium; Slender Bead Grass; Native; Locally common in
fields and roadsides, in both dry and moist soil. Very similar to P.
publiflorum but its spikelets are smaller -- less than 3 mm long.

Plants
• Phalaris arundinacea; Reed Canary
Grass; Native; Still uncommon in the Refuge, but could become invasive
and difficult to control. A sizable population can be seen near the
observation platform, west of Hwy 148. It is a circumpolar species,
native to North America, Europe and Asia. Photos
Phytoimages; USDA
Plants
• Phleum pratense; Timothy;
Introduced (Europe); Common in fields and roadsides throughout the
Refuge. In the 18th century this grass was introduced from Europe by a
fellow named Timothy Hanson. Hence its common name. Photos
Phytoimages; USDA
Plants
• Phragmites australis; Synonyms:
Phragmites communis; Reed; Native and Introduced (Native to Old World);
Ulaszek (1988) considers it uncommon. Undoubtedly by oversight not
listed in CCP. The plant is locally common along lakes shores and wet
places. Tall and adorned with a large plume, nonnative varieties of this
grass tend to be aggressive and can become very invasive. Yatskievych
(1999, p. 620)
reports that "P. australis has perhaps the broadest range of
any flowering plant species, occurring naturally on every continent
except Antarctica". Photos
Phytoimages; USDA
Plants
• Poa angustifolia; Narrow-leaved
(Smooth) Meadow Grass; Native; Uncommon to rare in fields and shaded
roadsides. Easily overlooked and very difficult to distinguish from the
very common P. pratensis. Jones (2005) considers it a variety
of P. pratensis. Yatskievych (1999) makes no mention of this
taxon. Photos
Phytoimages; USDA
Plants
• Poa annua; Annual
Bluegrass; Introduced (Eurasia); Locally common here and there in lawns,
moist disturbed places, fields and along trails, even in cracks in the
street. A cute bright green little grass, sometimes visible at all times
of the year. A similar native species, P. chapmaniana, was
collected by Garbaciak at Devil's Kitchen dam in 1956 (SIU herbarium),
and should be looked for in the Refuge. Photos
Phytoimages; USDA
Plants
• Poa bulbosa; Bulbous
Bluegrass; Introduced (Europe); Locally common in dry disturbed soil.
Can be found along Stringtown Road. An interesting grass: it multiplies
by forming bulblets. The plant does not produce grain. Photos
Phytoimages; USDA
Plants
• Poa compressa; Canadian
Bluegrass; Introduced (Eurasia); Common. In fields and roadsides, and in
openings in the woods. The plant can be recognized by its flat stems. Photos
Phytoimages; USDA

• Poa sylvestris; Woodland
Bluegrass; Native; Locally common in damp areas in the woods. A graceful
perennial plant without rhizomes. Can be found along Rocky Bluff and
Harmony Trails. Photos
Phytoimages; USDA
Plants
• Schedonosus pratensis; Synonym: F. elatior, F. pratensis; Meadow Fescue; Introduced (Europe); Common in disturbed places and roadsides throughout the Refuge. Schedonorus arundinacea and S. pratensis were formerly regarded as varieties of a single species, Festuca elatior. Schedonorus arundinacea is the taller and more robust of the two, with 4-5 flowered spikelets. The spikelets of S. pratensis are 6-10 flowered. Photos Phytoimages; USDA Plants
• Schizachyrium scoparium; Synonyms:
Andropogon
scoparius; Little Bluestem; Native; Abundant in woods, along roads, in
fields and dry disturbed areas. The plants turn reddish-orange in the
fall. Photos
