[Plantago virginica var. viridescens Fern.]
Plant: Annual herb; to 34.5 cm tall Leaves: petiolate; blades lanceolate, 2.5-10 cm long, 0.8-2.7 cm wide, attenuate at base, acute at apex, sparsely villous, distincly 3-veined, sometimes with 2-4 widely-spaced teeth INFLORESCENCE: pedunculate, scapose; PEDUNCLES 1-20 cm long. SPIKES 1.5-17 cm long, sparsely to densely villous; bracts subulate to narrowly or broadly triangular, 2-4.8 mm long, narrowly scarious-margined at base, ciliate Flowers: more or less dioecious; sepals ovate, 2.5-3 mm long, broadly scarious-margined, acuminate at apex, obtuse to subacute at base, hirsute only on midrib; corolla lobes erect, enclosing the capsule (sometimes spreading in staminate flowers), lanceolate, 2-3 mm long; stamens 4 Fruit: capsules, breaking at middle; SEEDS 2, ellipsoid, 0.9-3.0 mm long, 0.8-1.6 mm wide, light brown, the inner surface deeply concave, the outer surface furrowed Misc: Disturbed areas; 450-1300 m (1500-4200 ft.); Mar-Jul REFERENCES: Huisinga, Kristin D. and Tina J. Ayers. 1999. Plantaginaceae. Ariz. - Nev. Acad. Sci. 32(1).
Annual of biennial herb with a taproot flowering stem to 20 cm tall Leaves: basal, 5 - 10 cm long, reverse lance-shaped to reverse egg-shaped with a blunt apex, more or less parallel-veined, sometimes inconspicuously toothed, and hairy. Inflorescence: a dense spike of many flowers, arising from a leafless stalk (scape), 3 - 10 cm long, 6 - 8 mm wide, moderately woolly. Flowers: stalkless or nearly stalkless, subtended by lance-shaped bracts, not fragrant. Bracts minutely hairy. Stamens four, exserted, alternate with corolla lobes. Style one. Sepals: four, green, 2 - 2.5 mm long, oblong reverse egg-shaped with a rounded apex, scarious-margined (dry, thin, and membranous), with a minutely hairy keel. Fruit: a dehiscent capsule (circumscissile). Seeds two, pale brown, 1.3 - 2 mm long, less than half as wide, convex on one side, concave on the other. Corolla: four-lobed, whitish, scarious (dry, thin, membranous). Lobes upright, 1 - 3 mm long. The corollas of fertile flowers close over the maturing capsule.
Similar species: Plantago media is similar but its corollas do not close over the maturing capsules and the flowers are fragrant.
Flowering: May to early June
Habitat and ecology: Infrequent in the Chicago Region. Found in fallow fields and pastures. Often found in acid sandy soil.
Occurence in the Chicago region: native
Etymology: Plantago comes from the Latin word planta, meaning footprint. Virginica means "of or from Virginia."
Author: The Morton Arboretum
From Flora of Indiana (1940) by Charles C. Deam
Rare or absent from most of our northern counties, becoming frequent to common in the southern counties. It is found in both dry and moist habitats, but prefers slightly acid, moist soil and is usually found in fallow fields and pastures.

Duration: Annual Nativity: Native Lifeform: Forb/Herb General: Annual herb to 34.5 cm tall. Leaves: Petiolate, blades lanceolate 2.5-10 cm long, .8-2.7 cm wide, attenuate at base, acute at apex, sparsely villous, distinctly 3-veined, sometimes 2-4 widely-spaced teeth. Flowers: Peduncles 1-20 cm long, spikes 1.5-17 cm long, sparsely to densely villous, subulate bracts narrowly or broadly triangular, 2-4.8 mm long, narrowly scarious-margined at base, ciliate; more or less dioecious flowers, ovate sepals 2.5-3 mm long, 4 stamens. Fruits: Capsule breaks at middle. Ecology: Found in disturbed areas from 1,500-4,500 ft (457-1372 m); flowers March-July. Distribution: Most states in the U.S. except the northwest; south to s MEX.; also in Asia and Africa. Notes: This species distinguished by leaves lanceolate, >1 cm wide, acute at the apex and with 2-3 remote, shallow teeth; and corolla lobes strictly erect at maturity, enclosing the capsule. Similar to P. rhodosperma, but otherwise clearly distinguishable. Ethnobotany: Used ceremonially. Etymology: Plantago translates to foot-sole in reference to leaf habit on ground, while virginica means Virginia. Synonyms: Plantago virginica var. viridescens Editor: SBuckley 2010, FSCoburn 2015
