Annual grasses
Annual bluegrass seedling.
Annual bluegrass
(Poa annua): Grass family; winter annual or where irrigated a summer annual; leaf tip shaped like bow of a boat; membranous ligule rounded with slightly pointed tip; leaf blade crinkled at midsection.
Seedling of barnyardgrass, 
				Echinochloa crus-galli.
Barnyardgrass
(Echinochloa crus-galli): Grass family; summer annual; first leaf dull gray-green; stem flattened, purplish; no ligule.
Bearded sprangletop 
				seedling, Leptochloa fascicularis.
Bearded sprangletop
(Leptochloa fascicularis): Grass family; summer annual; first leaves light green, usually with white midrib; blades somewhat rolled; sheaths loose near base of plant; ligule long, thin, membranous and tears easily.
Green foxtail seedling
Green foxtail
(Setaria viridis): Grass family; summer annual; leaf blade is flat, light green, and narrow; sheath red purple around base of plant; no fine hairs on upper surface of leaf blade near collar (as in yellow foxtail); by pulling leaf sheath away from stem, fine hairs on sheath below collar region are revealed.
Crabgrass seedling.
Large crabgrass
(Digitaria sanguinalis): Grass family; summer annual; first leaf blade linear to lance shaped, with stiff, jagged, and papery ligule; hairs on margins of the collar wide; no auricles; leaves covered with coarse hairs; leaves rolled in bud.
Seedling of lovegrass, 
				Eragrostis sp., at the four-leaf stage.
Lovegrasses (Stinkgrasses)
(Eragrostis spp.): Grass family; winter or summer annuals or perennials, depending on the location and which of about one dozen species; a seedling's first leaf is inconspicuous; second and third leaves are light green, short, and roughly 1/10 inch (3 mm) wide with tufts of hair arising from base of the third leaf.
Seedling of yellow foxtail, Setaria pumila, at the four-leaf stage.
Yellow foxtail
(Setaria pumila): Grass family; summer annual; first blade linear, roughly 7 times longer than wide and opens almost parallel to ground; leaves rolled in bud; ligule—fringe of hairs; no auricles; no hairs on leaf-sheath margin below collar; leaf blades of young seedlings smooth on lower surface, with long hairs on basal area of upper surface; margins smooth or slightly rough.
Witchgrass
Witchgrass
(Panicum capillare): Grass family; summer annual; ligule is a fringe of short hairs; auricles are absent; light green to red purple and resembles crabgrass seedling but has slightly narrower leaf blades and longer silky hairs with swollen bases.
 
Perennial grasses
Seedling of 
					burmudagrass
Bermudagrass
(Cynodon dactylon): Grass family; perennial; first leaves with somewhat rough surface; ligule surrounded by ring of hairs with tuft of long hairs on either side; auricles absent; stem flat, wiry, and without hairs.
Dallisgrass leaf 
				sheath of the seedling.
Dallisgrass
(Paspalum dilatatum): Grass family; perennial; first leaves rolled in bud; ligule membranous and tall, with bluntly pointed or rounded tip; long, silky hairs at collar; no auricles; sheaths flattened with prominent midrib; first leaf sheaths softly hairy.
Johnsongrass 
					seedlings.
Johnsongrass
(Sorghum halepense): Grass family; perennial; first leaves with white midvein, 8 times longer than wide and rolled in bud; ligule membranous below and fringed or toothed above; no auricles.
Sedges
Young yellow 
				nutsedge plant.
Yellow nutsedge
(Cyperus esculentus): Sedge family; perennial; grasslike; light green blades, flat, slender; leaf tip long and drawn out; nutlets globe shaped, smooth, and almond flavored.

Purple nutsedge seedling
(Seedlings rarely occur, most plants from rhizomes and/or tubers)
Purple nutsedge
(Cyperus rotundus): Sedge family; perennial; (young plant) young shoot somewhat stiff, upright, and light green with a fairly prominent whitish midvein; no auricle or ligule; triangular stem solid or pithy and rarely hollow as in grasses. (seedling) 2 to 3 newly emerged leaves with smooth, membranous, linear blades folded lengthwise; sheaths tubular.
