Cyperaceae
• Bulbostylis capillaris; Hair
Sedge;
Native; According to Ulaszek (1988), uncommon on sandstone glades.
Mohlenbrock (2014) lists this plant as occasional in moist sandy soil
throughout the state. Not yet relocated in the Refuge. To quote
Yatskievych (1999) "This small, wispy plant is easily overlooked in the
field". Photos
Phytoimages; USDA
Plants
• Carex albicans; Synonyms: Carex
artitecta; White-tinged Sedge; Native; Common to abundant in dry woods
throughout the Refuge. It is one of the first sedges to flower in the
spring. Photos
Phytoimages; USDA
Plants
• Carex albursina; White Bear
Sedge; Native; Common in upland forests throughout the Refuge. Easily
identified by its broad vegetative leaves. The common name derives from
the name of a lake in Minnesota. Photos
Phytoimages; USDA
Plants
• Carex amphibola; Creek Sedge;
Native; Occasional to rare. Occurs along a trail in the Grassy Creek
national wilderness area off Tacoma Lake Road. This sedge is sometimes
described as a variety of the more common C. grisea.
Distinguished from C. grisea by the narrowly elliptic
triangular perigyngia, and the presence of pistillate spikes near the
base of the plant. Photos

• Carex annectens; Yellow-brown
Fox Sedge; Native; Herbarium specimen by Mark Basinger 1992, in the
Devil's Kitchen Spillway area, accession no. 126925. Photos
Phytoimages; USDA
Plants
• Carex blanda; Common Wood
Sedge; Native; ]. Both Ulaszek (1988) and CCP list this plant as
occasional. Actually it is one of our most common sedges. It occurs in
woods, road edges, fields, and prairies, even in disturbed areas. Photos
Phytoimages; USDA
Plants
• Carex bushii; Bush's Sedge;
Native; Common in dry woods, fields and meadows, as well as in moist
situations, throughout the Refuge. Jones describes its habitat as "open
wet areas." Apparently the plant is infrequent in Kentucky. Photos
Phytoimages; USDA
Plants
• Carex caroliniana; Carolina Sedge;
Native; Uncommon. Can be found along Rocky Bluff Trail. This sedge
resembles C. bushii, but can be separated by its much shorter pistillate
scales. In C. bushii the scales are distinctly longer than the
perigyngia. Photos
Phytoimages; USDA
Plants
• Carex cephalophora; Capitate Sedge; Native; A common
sedge, occurring in woods, fields, thickets, and shaded roadsides. The
spikelets clustered at the tip of the culm help identify this taxon. Photos
Phytoimages; USDA
Plants
• Carex crinita; Fringed Sedge; Native; This robust,
striking plant, readily identified by its conspicuous pendulant
inflorescences, is locally common along the shores of all three lakes
and in wet areas. One of our more beautiful sedges. Photos
Phytoimages; USDA
Plants
• Carex cristatella; Round-spikelet Sedge; Native;
According to Ulaszek (1988), uncommon in moist successional
fields. I have not yet observed it on the Refuge. The plant's
range is generally north of us, though Mohlenbrock (2014) reports it as
scattered throughout the state. It does not occur in the southeastern
half of Missouri (Yatskievych 1999, map 179). The spiny look of the
globose spikes makes the plant relatively easy to identify. Photos
Phytoimages; USDA
Plants
• Carex davisii; Davis' Sedge; Native; Uncommon in
dry woodlands. It occurs along Rocky Bluff Trail. A rather delicate,
frequently spreading sedge. Photos
Phytoimages; USDA
Plants
• Carex digitalis; Slender
Woodland Sedge; Native; Photos
Phytoimages; USDA
Plants
• Carex emoryi; Emory's Sedge;
Native; Ulaszek (1988) found this plant along the margins of Devil's
Kitchen Lake and considered it uncommon. Mohlenbrock (2014)
reports it as "occasional in the northern 2/3 of Illinois: also in
Johnson, Union, Randolph, and Williamson counties." Not yet confirmed.
Probably overlooked, in spite of its hefty appearance. Photos
Phytoimages; USDA
Plants
• Carex festucacea; Fescue Sedge;
Native; Occasional in wet areas in fields. Occurs along Pigeon Creek
Road. May be more common, but is easily confused with other Ovales sedge
species. To identify it requires close examination of its peculiarly
orbicular perigynia. The Ovales form a subsection of Carex,
easily recognized as a group, but identifying species within the
group presents a formidable challenge! Yatskievych (1999) in his
introduction to the Ovales gives good advice: "When examining spikes, it
is important to locate the most mature, best developed peryginia in a
sample, as these facilitate interpretation of subtle characters of
peryginium shape, size, and texture". In practice this means that at
certain times some sedges cannot be reliably identified. Photos
Phytoimages; USDA
Plants
• Carex frankii; Frank's Sedge;
Native; A distinctive, sturdy sedge, locally common in moist places in
both forests and ditches, as well as along banks of ponds and lakes
throughout the Refuge. From a distance may be confused with C.
squarrosa. Photos
Phytoimages; USDA
Plants
• Carex glaucodea; Blue Sedge;
Native; Mohlenbrock (2014) describes this plant as occasional in the
southern 3/5 of the state. In the Refuge it is a common sedge, found in
woods and nearby fields. Easily identified by its glaucous bluish
leaves. Photos
Phytoimages; USDA
Plants
• Carex granularis; Meadow Sedge;
Native; Common in grassy areas. It can be found in the prairie across
from Harmony Trail. Its perigynia appear a tad inflated. Photos
Phytoimages; USDA
Plants
• Carex grayi; Gray's Sedge;
Native; This distinctive and easily recognized sedge occurs infrequently
in moist areas along Rocky Bluff Trail, the A-41 wetlands, and other
damp areas. Its large globose pistillate spike, armed with many spines
pointing in all directions, resembles the head of a caveman's club. Photos
Phytoimages; USDA
Plants
• Carex grisea; Gray Sedge;
Native; Uncommon in roadside ditches. Occurs in the boat launch area at
the south end of Little Grassy Lake (north of Giant City campground).
Similar to C. amphibola (see above under that species). Photos
Phytoimages; USDA
Plants
• Carex hirsutella; Hairy-leaved
Sedge; Native; Common in woods and meadows throughout the Refuge. Aptly
named, as its leaves are densely hairy on both sides. The base of the
flowering stem often shows a reddish or purplish tint. Photos
Phytoimages; USDA
Plants
• Carex hirtifolia; Hairy Sedge;
Native; Rare in the Refuge. It is not listed in Ulaszek (1988) or CCP.
It occurs at the north edge of the Prison Research Natural Area. Mark
Basinger collected this plant in the Devil's Kitchen Spillway area (SIU
herbarium). In 1974 Mohlenbrock (Flora of Southern Illinois) considered
it rare. In 2002 (and 2014) he judges it to be common throughout the
state. Photos
Phytoimages; USDA
Plants
• Carex hystricina; Synonyms: Carex
hystericina; Bottlebrush / Porcupine Sedge; Native; Ulaszek (1988) and
CCP lists this species as locally common in successional fields. I have
not yet observed it on the Refuge. Mohlenbrock (2014) states that this
species is occasional to common in the northern 2/3 of the state, rare
elsewhere. Jones lists it as "historical," hence this species probably
no longer occurs in Kentucky. Photos
Phytoimages; USDA
Plants
• Carex jamesii; James' Sedge; Native; CCP and
Ulaszek (1988) regard this neat little sedge as occasional. It is quite
common in dry forest areas throughout the Refuge. Easily found along
Rocky Bluff Trail. Photos
Phytoimages; USDA
Plants
• Carex lurida; Lurid Sedge; Native; Not yet
observed, possibly by oversight, as this species is said to be common in
moist areas throughout the state. Ulaszek (1988) reports it as locally
common along Devil's Kitchen Lake. The plant closely resembles C.
hystricina. According to Jones (2005) it is frequent in Kentucky.Photos
Phytoimages; USDA
Plants
• Carex meadii; Mead's Sedge; Native; CCP and
Ulaszek (1988) list this species as uncommon in successional fields (supported by Mohlenbrock 2014).
Not yet relocated. Photos
Phytoimages; USDA
Plants
• Carex molesta; Confusing Sedge; Native;
Locally common. Can be found along Devil's Kitchen Lake north of the dam
on Tacoma Lake Road. This plant resembles similar species in the
difficult Ovales group, such as C. festucacea and C.
normalis. The size and shape of the perigynia allow the careful
observer to make a determination. Its common name offers an appropriate
reminder! Photos
Phytoimages; USDA
Plants
• Carex muehlenbergii; Muhlenberg's Bracted Sedge; Native;
Common throughout the Refuge in woods, fields and along roadsides. Photos
Phytoimages; USDA
Plants
• Carex normalis; Greater Straw Sedge; Native; This
plant is common in fields and ditches and other moist areas throughout
the Refuge. The species, another one of the Ovales group, can be
difficult, and in some cases pretty well impossible, to identify with
certainty. Photos
Phytoimages; USDA
Plants
• Carex oligocarpa; Sparse-fruited Sedge; Native; Both
CCP and Ulaszek (1988) rightly consider this plant rare. The perigynia
are loosely spaced and form two ranks on opposite sides of the spike's
axis. It can be found in woods along Rocky Bluff Trail. Photos
Phytoimages; USDA
Plants
• Carex pensylvanica; Pennsylvania Sedge; Native; CCP and
Ulaszek (1988) report this species as locally common. However, I suspect
occasional misidentification. Its range is normally well to the north of
us. The plant closely resembles the more common C. albicans
and especially C. physorhyncha. Photos
Phytoimages; USDA
Plants
• Carex physorhyncha; Stellate Sedge, Bellow's Beak Sedge;
Native; ]. CCP lists this species as locally common. Ulaszek (1988)
considered it rare in dry upland forest. I judge it as uncommon in
dry upland woods, e.g., along the east side of Devil's Kitchen Lake. Its
status as a full species is in question. Yatskievych (1999) takes it to
be C. albicans var. australis. Jones (2005) does not
mention the plant. Rhizomes distinguish C. physorhyncha from C.
albicans. Note: Ulaszek (1988) reports that C. physorhyncha
was listed as endangered by C. J. Sheviak (Illinois Department of
Conservation) already back in 1981. Recently (2011) it was still so
listed by the Illinois Endangered Species Protection Board.
Clearly, this taxon will need attention.

• Carex radiata; Star Sedge; Native; Uncommon. Occurs
at Rocky Bluff. This plant is easily confused with C. rosea
and C. retroflexa. The beak of the perigynium of this species
is minutely toothed. The stigmas are straight. Photos
Phytoimages; USDA
Plants
• Carex retroflexa; Reflexed Sedge; Native; Occasional
to locally common, e.g., in the woods around Rocky Bluff Trail. The
plant closely resembles similar sedges, such as C. rosea, C.
radiata, and C. texensis. The beak of the peryginium is
smooth. The stigmas are straight. Photos
Phytoimages; USDA
Plants
• Carex rosea; Synonyms: Carex convoluta; Star
Sedge; Native; CCP and Ulaszek (1988) divide this species into two taxa:
C. rosea and C. convoluta. Both should be treated as
C. rosea. This species is the most common of several
similar-looking sedges (C. radiata, C. retroflexa,
and C. texensis), widespread throughout the Refuge in woods
and adjacent fields. The beak of the peryginium is roughened, and the
stigmas are twisted. Photos
Phytoimages; USDA
Plants
• Carex scoparia; Broom Sedge; Native; This plant
likes it wet. It can be found along the shore on the east side of
Devil's Kitchen Lake. Although it belongs to the Ovales, the pointed
spikes of this sedge are distinctive. Photos
Phytoimages; USDA
Plants
• Carex shortiana; Short's Sedge;
Native; Locally common. Can be found along Devil's Kitchen Lake north of
the dam on Tacoma Lake Road. The reddish-brown spikes are characteristic
of this attractive sedge. Photos
Phytoimages; USDA
Plants
• Carex squarrosa; Squarrose
Sedge; Native; Locally common. In moist places along Harmony Trail. From
a distance may be confused with C. frankii, but, unlike that
species, C. squarrosa frequently shows only one spike at the
tip of the culm. Photos
Phytoimages; USDA
Plants
• Carex styloflexa; Bent Sedge;
Native; According to CCP and Ulaszek (1988), uncommon in upland forests.
Mohlenbrock (2014) calls it rare, confined to 1/6 of southern Illinois.
He did not list it in the 1959 edition of A Flora of Southern
Illinois. Jones (2005) reports it as rare in areas of Kentucky
well to the east of us, but does not mark it as of special concern. The
plant evidently does not occur in Missouri: Yatskievych (1999) makes no
mention of it. This sedge is similar to C. digitalis, and may
be easily overlooked. Note: Ulaszek (1988) reports that Carex styloflexa
was listed as endangered in Illinois by Sheviak (1981). He adds:
"Previously known in Illinois from one locality in Jackson County."
Ulaszek (1988) collected this plant in dry-mesic upland forest in the
Devil's Kitchen Dam RNA in 1983. This evidently rare species is not on
the 2011 Endangered Species Protection Board list. Photos
Phytoimages; USDA
Plants
• Carex swanii; Swan's Sedge;
Native; Rare. In woods along west side of Devil's Kitchen Lake. Not
listed in CCP or reported by Ulaszek (1988). It is one of the few sedges
in our area distinguished by hairy leaves, culms, and peryginia. Photos
Phytoimages; USDA
Plants
• Carex tenera; Remote Sedge;
Native; CCP and Ulaszek (1988) report this species as uncommon in dry,
upland forest. Mohlenbrock (2014) assigns the species to
floodplain woods, wet meadows, and swampy depressions, and considers it
occasional to common throughout the state. Yatskievych (1999), however,
insists that all reports of C. tenera -- another member of the
troublesome Ovales group -- south of northwest Missouri are based on
mistaken identity, this species being confused with the very similar C.
normalis, C. molesta, and C. festucacea.
Jones (2005) does not report C. tenera as occurring in
Kentucky. Hence the status of this species as a bona fide inhabitant of
the Refuge remains questionable. Photos
Phytoimages; USDA
Plants
• Carex texensis; Texas Sedge;
Native; Uncommon to occasional. The plant is very similar to C.
rosea (see above) and can be found along Harmony Trail. The
smooth beak of the peryginia suggests C. retroflexa (of which
it is sometimes regarded as a variety). Narrow peryginia and leaves help
identify C. texensis. Photos
Phytoimages; USDA
Plants
• Carex torta; Twisted Sedge;
Native; CCP and Ulaszek (1988) report this species as locally abundant
in perennial streams. Mohlenbrock (2014) lists it as occasional in the
southern tiers of counties. Not yet relocated. Photos
Phytoimages; USDA
Plants
• Carex tribuloides; Blunt Broom
Sedge; Native; A locally common sedge in moist to wet areas throughout
the Refuge. It, too, belongs to the challenging Ovales group. The
perigynia of this species, however, are noticeably elongated
(lanceolate). Photos

• Carex typhina; Cat-tail Sedge;
Native; Herbarium specimen by Mark Basinger 1992, Devil's Kitchen Lake
north of campgorund, accession no. 126944. Photos
Phytoimages; USDA
Plants
• Carex umbellata; Parasol Sedge;
Native; Ulaszek (1988) considers this low-growing inconspicuous sedge to
be occasional in dry and dry-mesic upland forest. Mohlenbrock (2014)
reports it to be very rare in Jackson, Pope, and Randolph Counties. No
doubt easily overlooked. It is a wide-ranging sedge, scattered
throughout the eastern half of North America. I have not yet seen it in
the Refuge. Photos

• Carex vulpinoidea; Fox Sedge;
Native; ]. A very common sedge in wet meadows, fields and ditches
and low grounds generally, throughout the Refuge. Photos
Phytoimages; USDA

• Cyperus acuminatus; Pointed /
Tapertip Flatsedge; Native; Occasional in wet areas. This neat little
flatsedge can be found in, for example, wet grassy areas near the
Spillway main boat ramp at Crab Orchard Lake. Photos
Phytoimages; USDA
Plants
• Cyperus bipartitus; Synonyms:
Cyperus rivularis; Slender Flatsedge; Native; Uncommon. Occurs in same
areas as C. acuminatus, e.g., near the Spillway boatramp at Crab Orchard
Lake. A cute, low-growing flatsedge. Photos
Phytoimages; USDA
Plants
• Cyperus echinatus; Synonyms:
Cyperus ovularis; Round-headed Flatsedge; Native; Though listed by CCP
as occasional, this pretty plant is among the most common of flatsedges,
widespread throughout the Refuge in fields, disturbed areas, and dry
woods. Easily recognized by its globular inflorescence. Photos
Phytoimages; USDA
Plants
• Cyperus erythrorhizos; Red-rooted
Flatsedge; Native; Locally common. Can be found in sandy parts of the
Crab Orchard Lake and Little Grassy Lake shorelines. Photos
Phytoimages; USDA
Plants
• Cyperus esculentus; Yellow Nut
Sedge; Native; ]. In fields and disturbed soil throughout the
Refuge. This plant can be a troublesome weed. The positive side of C.
esculentus is that its tubers offer good food for gamebirds and
waterfowl. Photos
Phytoimages; USDA
Plants
• Cyperus lupulinus; Synonyms:
Cyperus filiculmis; Fern Flatsedge; Native; Ulaszek (1988) reports this
species as rare on sandstone glades. The plant appears to be more common
in the northern 1/2 of the state. It readily hybridizes with other Cyperus
species. I have not seen it on the Refuge. Photos
Phytoimages; USDA
Plants
• Cyperus odoratus; Synonyms:
Cyperus ferruginescens; Rusty (Slender) Flatsedge; Native; Locally
common in wet areas. Occurs, e.g., in wetlands along Pigeon Creek Road
and moist areas along the lakes. Photos
Phytoimages; USDA

• Cyperus pseudovegetus; Flatsedge;
Native; Photos
Phytoimages; USDA
Plants
• Cyperus squarrosus; Synonyms:
Cyperus aristatus; Bearded Flatsedge; Native; A small, distinctive
mat-forming flatsedge, locally common in wet areas, such as the shores
of Little Grassy Lake and Crab Orchard Lakes. Photos
Phytoimages; USDA
Plants
• Cyperus strigosus; Straw-colored
Flatsedge; Native; Common in fields, roadsides, pond margins and
disturbed areas throughout the Refuge. The plant resembles C.
esculentus, but lacks the tuberous rhizomes. Photos
Phytoimages; USDA
Plants
• Eleocharis acicularis; Needle Spike
Rush; Native; This low-growing mat-forming spike rush is locally common
in wet areas along Little Grassy and Devil's Kitchen Lake. It also grows
as a submerged plant. Photos
Phytoimages; USDA
Plants
• Eleocharis elliptica; Elliptic Spike
Rush; Native; CCP and Ulaszek (1988) report this plant as uncommon. It
is closely related to the more widespread E. compressa (Flat-stemmed
Spike Rush), of which it is sometimes regarded a variety. Yatskievych
(1999) states that E. elliptica occurs in the northeastern U.S and
adjacent Canada. Apparently it does not occur in Missouri. Jones (2005)
says that E. elliptica "is to be expected" in Kentucky.
Mohlenbrock (2014), however, lists it as occasional throughout Illinois.
Some diligent searching may relocate this species in the Refuge. Photos
Phytoimages; USDA
Plants
• Eleocharis ovata; Synonyms:
Eleocharis obtusa; Blunt (Annual) Spikerush; Native; This is the common
spike rush in the Refuge, growing at margins of ponds, in shallow water,
wet disturbed areas and ditches. The precise taxonomy of this species is
not clear. E. ovata appears to represent a complex of several
taxa. It is morphologically quite variable, a feature that prompted
botanists to recognize many subspecies, some of which are thought to be
distinct species. Photos
Phytoimages; USDA
Plants
• Eleocharis quadrangulata; Square-stemmed
Spike
Rush; Native; Herbarium specimen by Bailey & Swayne 1949, at SE
shore of Crab Orchard Lake
accession no. 5367.
An examination of this specimen in the SIU herbarium suggests this
identification is correct. Photos
Phytoimages; USDA
Plants
• Eleocharis verrucosa; Synonyms:
Eleocharis tenuis; Warty Spike Rush; Native; Herbarium
specimen by Hatcher & Stewart 1951, at the west edge of
Crab Orchard Lake, accession no. 5291. Some botanists view E.
verrucosa as a variety of E. tenuis. Photos
Phytoimages; USDA
Plants
• Fimbristylis annua; Annual Fimbry;
Native; Mohlenbrock (2014) reports this taxon as rare in southern
Illinois, documented only in Alexander, Johnson, and Massac counties. It
can be found along the shore of Crab Orchard Lake near the Marina boat
dock. It grows intermingled with Cyperus squarrosus. The
following features distinguish this taxon from F. autumnalis:
the spikelets show two instead of three stigmas; one of the bracts below
the inflorescence is much elongated, giving the inflorescence a lateral
appearance, and the margins of the leaves are minutely hairy (ciliate).
Photos
Phytoimages; USDA
Plants
• Fimbristylis autumnalis; Slender
Fimbry;
Native; Mohlenbrock (2014) reports this species as occasional throughout
the state. CCP and Ulaszek (1988) do not list it. Extensive populations
can be found along muddy sections of the Little Grassy Lake
shoreline. Photos
Phytoimages; USDA
Plants
• Schoenoplectus acutus; Synonyms:
Scirpus acutus; Hard-stem Bulrush; Native; CCP lists this plant as rare.
Ulaszek (1988) does not report it. According to Mohlenbrock (2014), S.
acutus var. acutus occurs occasionally throughout the
state, while S. acutus var. congestus is rare in
Lake and Williamson counties. The latter may refer to a record from the
Refuge. A single specimen collected in 1951 is in the SIU herbarium. I
have not observed this species in the Refuge. Photos

Crab Orchard Lake, accession no. 5510. Photos
Phytoimages; USDA
Plants
• Schoenoplectus pungens; Common
Three-Square;
Native; Uncommon. Most easily found near the boat ramp at Crab Orchard
Lake off Spillway. It is the only Schoenoplectus Bulrush in
our area with a sharply triangular stem. It also occurs in Europe and
Australia. Photos
Phytoimages; USDA

• Schoenoplectus tabernaemontani; Synonyms: Scirpus validus; Soft-stem Bulrush; Native; Soft-stem
Bulrush]. Locally common in marshy places. Can be found along the
margins of Devil's Kitchen Lake. This plant also occurs in Europe and
Asia. Photos
Phytoimages; USDA
Plants
• Scirpus atrovirens; Dark Green
Bulrush; Native; CCP, Ulaszek (1988), and Mohlenbrock (2014) all
consider this plant to be (locally) common. I suspect frequent
misidentification, the species being confused with the much more common
but very similar S. georgianus. Thus far every Dark Green
Bulrush I have examined in the Refuge turned out to be S.
georgianus. Yatskievych (1999, p. 432)
points out that S. atrovirens occupies a more northerly range,
while S. georgianus is a southern taxon. Photos

Plants
• Scirpus cyperinus; Wool Grass;
Native; This species is locally common along the shores of the three
lakes and other swampy areas. Its large, arched inflorescence,
composed of up to 500 spikelets, makes this striking plant easy to
identify. Photos
Phytoimages; USDA

• Scirpus georgianus; Georgia
Bulrush; Native; Common to abundant in the Refuge in ditches, wet
places, roadsides and disturbed areas. See comment under S.
atrovirens above. Photos
Phytoimages; USDA
Plants
• Scirpus pendulus; Nodding (Red)
Bulrush; Native; Uncommon to locally common in wet areas, especially
along the shoreline of Devil's Kitchen Lake. Superficially resembles S.
cyperinus, but the branches of the inflorescence end in a
solitary spikelet, rather than in a cluster of spikelets. Photos
Phytoimages; USDA
Plants
• Scleria pauciflora; Few-flowered
Nut Rush; Native; A rare plant. Ulaszek (1988) found it on a sandstone
glade just south of the Williamson/Union county line on the west side of
Devil's Kitchen Lake. In a personal communication Jack White reported
his recent attempt to relocate it but could not find it again. I have
not yet been able to locate it either. It might be easily overlooked.
Yatskievych (1999) reports that in Missouri a closely related species, S.
ciliata, occurs more commonly than S. pauciflora. Scleria
ciliata is listed as endangered in Kentucky. Apparently it has
not yet been found in Illinois, hence Mohlenbrock (2014) makes no
mention of it. Photos
