Bartonia virginica is species of flowering plant in Gentianaceae. It is the commonly called yellow screwstem or yellow bartonia and it is an annual species with small pale green to yellow flowers. [2]
Bartonia virginica is an annual plant, [3] that typically has simple stems that are wiry and erect. The stems are 1–4 dm tall, with opposite, strongly ascending branches. The leaves are scale-like usually opposite. The flowers are arranging in racemose or paniculate inflorescence, which have commonly opposite, very upright branches and pedicels. Each flower is 3–4 mm long with lance-subulate shaped sepals. The petals are oblong in shape and usually have denticulate margins and are abruptly narrowed to a rounded or obtuse, often mucronate tip. The anthers are minutely apiculate. It flowers late summer. The diploid (2n) chromosome count is fifty-two. [4] [5]
Bartonia virginica grows in sphagnum bogs and wet meadows, where it is found in acids bogs with sphagnum or Polytrichum mosses. [5]
The native distribution of Bartonia virginica is eastern North America and is centered around the Atlantic coastal plain, with scattered inland populations. [5] It has been found in Quebec and Nova Scotia of Canada to the US states of Wisconsin south to Florida and Louisiana. It reaches the most western part of its range in eastern Minnesota, where it is very rare and listed as endangered, having been recorded in Goodhue and Anoka counties in white cedar swamps and peat bogs.

Forsythia, is a genus of flowering plants in the olive family Oleaceae. There are about 11 species, mostly native to eastern Asia, but one native to southeastern Europe. Forsythia – also one of the plant's common names – is named after William Forsyth.
Sphagnum is a genus of approximately 380 accepted species of mosses, commonly known as sphagnum moss, peat moss, also bog moss and quacker moss. Accumulations of Sphagnum can store water, since both living and dead plants can hold large quantities of water inside their cells; plants may hold 16 to 26 times as much water as their dry weight, depending on the species. The empty cells help retain water in drier conditions.
Bartonia is a genus of the gentian family, tribe Gentianeae, subtribe Swertiinae. Members of this genus are called screwstems. Bartonia was also the name of a genus in the Loasaceae family, but those species are now generally classified under the genus Mentzelia.
Drosera anglica, commonly known as the English sundew or great sundew, is a carnivorous flowering plant species belonging to the sundew family Droseraceae. It is a temperate species with a circumboreal range, although it does occur as far south as Japan, southern Europe, and the island of Kauai in Hawaii, where it grows as a tropical sundew. It is thought to originate from an amphidiploid hybrid of D. rotundifolia and D. linearis, meaning that a sterile hybrid between these two species doubled its chromosomes to produce fertile progeny which stabilized into the current D. anglica.
Cardamine bulbosa, commonly called bulbous bittercress or spring cress, is a perennial plant in the mustard family. It is native to a widespread area of eastern North America, in both Canada and the United States. Its natural habitat is moist soils of bottomland forests and swamps, often in calcareous areas.
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.
Hammarbya paludosa is a small orchid commonly known as bog orchid, bog adder's-mouth or bog adder's-mouth orchid. It grows in bogs in temperate and subarctic regions of the Northern Hemisphere.
Lysimachia terrestris is a plant in the family Primulaceae.
Eupatorium sessilifolium, commonly called upland boneset or sessile-leaved boneset, is a North American plant species in the family Asteraceae. It is native to the eastern and central United States, found from Maine south to North Carolina and Alabama, and west as far as Arkansas, Kansas, and Minnesota.
Agalinis paupercula, commonly known as the smallflower false foxglove, is a hemiparasitic annual plant native to the eastern parts of the United States and Canada. Found in open, moist areas, its purple flowers are borne on a 30-to-70-centimeter stem, and bloom in August and September. The species has often been treated as a variety of Agalinis purpurea, the purple false foxglove, and preliminary genetic evidence suggests that the two are, in fact, a single species.
Sericocarpus linifolius, the narrowleaf whitetop aster or flax leaf whitetop, is a perennial forb native to the eastern United States, that produces white composite flowers in summer.
Sphagnum cuspidatum, the feathery bogmoss, toothed sphagnum, or toothed peat moss, is a peat moss found commonly in Great Britain, Norway, Sweden, the eastern coast of the United States, and in Colombia.
Arnica lonchophylla is a species of flowering plant in family Asteraceae. The common names for this species includes longleaf arnica, northern arnica, and spear-leaved arnica. It has daisy-like yellow flowers that are 2.5 to 5 cm across with a yellow center disks.
Hypericum boreale, also known as northern St. John's-wort, is a short-lived perennial species of flowering plant in the family Hypericaceae, section Trigynobrathys.
Asclepias hirtella, commonly called the tall green milkweed, is a species of flowering plant in the milkweed genus and dogbane family (Apocynaceae). It is native to Canada and the United States, where its range is concentrated in the Midwest and Upper South.
Boechera retrofracta is a species of flowering plant in family Brassicaceae. The common names include reflexed rockcress.
Asclepias stenophylla is a species of flowering plant in the dogbane family (Apocynaceae) commonly called slimleaf milkweed and narrow-leaved green milkweed.
