Obolaria virginica L. | |
Obolaria is a genus of flowering plant in the gentian family Gentianaceae. It is monotypic, being represented by the single species Obolaria virginica, commonly known as Virginia pennywort. [1]
It is native to the eastern United States, [2] where it is found in nutrient-rich forests. It is believed to be mycoheterotrophic, getting much of its nutrients though a symbiotic relationship with fungi, instead of through its small purplish-green leaves. [3] [4]
It is a perennial that produces white flowers in the spring. It is often difficult to locate due to its small stature, and tendency to be buried under leaf litter. [3] [5]
Gentianaceae is a family of flowering plants of 103 genera and about 1600 species.
Silene virginica, the fire pink, is a wildflower in the pink family, Caryophyllaceae. It is known for its distinct brilliant red flowers. Fire pink begins blooming in late spring and continuing throughout the summer. It is sometimes grown in wildflower, shade, and rock gardens.
Claytonia virginica, the Virginia springbeauty, eastern spring beauty, grass-flower or fairy spud, is an herbaceous perennial plant in the family Montiaceae. Its native range is eastern North America. Its scientific name honors Colonial Virginian botanist John Clayton (1694–1773).
Mertensia virginica is a spring ephemeral plant in the Boraginaceae (borage) family with bell-shaped sky-blue flowers, native to eastern North America.
Gentiana andrewsii, the bottle gentian, closed gentian, or closed bottle gentian, is an herbaceous species of flowering plant in the gentian family Gentianaceae. Gentiana andrewsii is native to northeastern North America, from the Dakotas to the East Coast and through eastern Canada.
Paronychia is a genus of plants in the family Caryophyllaceae with over 110 species worldwide, mostly from warm-temperate North America, Eurasia, South America and Africa. They are herbs that are annual or biennial or perennial in life span. Some species have a woody base. For the most part they have small, white to yellow-white colored flowers that are often hidden within the paired bracts.
Eriogonum longifolium var. harperi, also known as Harper's buckwheat or Harper's umbrella plant, is a dicot of the family Polygonaceae, found in areas of nutrient-poor shale soils in Alabama, Kentucky and Tennessee. It lives inconspicuously in an immature vegetative stage for four or more years before developing a flowering stalk, then flowers and dies. It is listed as an endangered species by the state of Tennessee. It has eleven small populations in Alabama and five in Tennessee but its survival in Kentucky is uncertain. According to a leading expert, Professor James L. Reveal of the University of Maryland, its Kentucky population has been reportedly extirpated. Its 2006 Alabama Natural Heritage Program ranking was G4T2S1, demonstrating an opinion that it was "critically imperiled" in that state.
Microstegium vimineum, commonly known as Japanese stiltgrass, packing grass, or Nepalese browntop, is an annual grass that is common in a wide variety of habitats and is well adapted to low light levels.
Itea virginica, commonly known as Virginia willow or Virginia sweetspire, is a small North American flowering shrub that grows in low-lying woods and wetland margins. Virginia willow is a member of the Iteaceae family, and native to the southeast United States. Itea virginica has small flowers on pendulous racemes.
Peltandra virginica is a plant of the arum family known as green arrow arum and tuckahoe. It is widely distributed in wetlands in the eastern United States, as well as in Quebec, Ontario, and Cuba. It is common in central Florida including the Everglades and along the Gulf Coast. Its rhizomes are tolerant to low oxygen levels found in wetland soils. It can be found elsewhere in North America as an introduced species and often an invasive plant.
Iris virginica, with the common name Virginia blueflag, Virginia iris, great blue flag, or southern blue flag, is a perennial species of flowering plant in the Iridaceae (iris) family, native to central and eastern North America.
Anchistea is a genus of leptosporangiate ferns in the family Blechnaceae. It has only one species, Anchistea virginica the Virginia chain fern, which has long creeping, scaly, underground stems or rhizomes giving rise to tall widely separated, deciduous, single leaves. In contrast, the leaves of Osmundastrum cinnamomeum, which can be mistaken for A. virginica, grow in a group from a crown. Also in contrast to O. cinnamomeum the leaves are monomorphic without distinct fertile fronds. The lower petiole or stipe is dark purple to black, shiny and swollen, the upper rachis is dull green. The leaf blade is green and lanceolate, composed of 12 to 23 paired, alternate pinnatifid pinnae. The pinnae are subdivided into 15 to 20 paired segments that are ovate to oblong. The lower rachis is naked for about half its length. The sori or spore-producing bodies are found on the underside of the pinnae and are long and form a double row which outlines the major veins of the pinnae. In common with all ferns, A. virginica exhibits a gametophyte stage in its life cycle and develops a haploid reproductive prothallus as an independent plant. The spores are produced in red-brown sori which line the spaces (areolae) between the costa and costules.

Claytonia caroliniana, the Carolina springbeauty, is an herbaceous perennial in the family Montiaceae. It was formerly placed in the Portulacaceae. Its native range is eastern and central North America. It is most commonly found in the New England area of the United States but its habitat extends from Ontario and a northern limit in the Cape Anguille Mountains of Newfoundland and south to Alabama. It grows approximately 6 inches tall in forests of the Appalachian Mountains and piedmont

It is found in a variety of natural habitats, particularly in open woodlands and along riverbanks. It is a somewhat weedy species that responds positively to ecological disturbance, and can be found in degraded habitats such as agricultural fields.

It is an annual plant, blooming around the month of May.
