Flora of New Jersey

Boltonia montana, the mountain doll's daisy, is a North American species of plants in the family Asteraceae. It is found only in the east-central part of the United States, in the states of New Jersey, Pennsylvania, and Virginia. Boltonia montana is a perennial herb up to 150 cm (60 inches) tall. It has many daisy-like flower heads with pink or lavender ray florets and yellow disc florets. Boltonia montana is critically imperiled in New Jersey and Virginia, and is possibly extirpated in Pennsylvania. In 2010, there were only 11 occurrences. The long term trend is a decline of 30-50%. It is

Rhynchospora knieskernii is a rare species of sedge known by the common name Knieskern's beaksedge. It is endemic to the state of New Jersey in the United States, where it occurs naturally in the Pine Barrens. Reports have cited it present in Delaware as well, but these populations appear to have been introduced. It is threatened by the destruction and degradation of its habitat. It is a federally listed threatened species of the United States. This perennial sedge produces clumps of very narrow, triangular stems lined with thin leaves. Inflorescences occur at the tips and on the sides of the

Narthecium americanum is a species of flowering plant in the Nartheciaceae known by the common names yellow asphodel and bog asphodel. It is native to New Jersey in the United States. It is now apparently limited to that state, having likely been extirpated from Delaware, North Carolina, and South Carolina. This rhizomatous perennial herb produces an erect stem 25 to 45 centimeters tall. It has narrow linear leaves up to 20 centimeters long by just a few millimeters wide around the base of the stem. Smaller leaves occur higher on the stem. The inflorescence is a dense raceme of yellow flowers

Eupatorium resinosum, the pine barren thoroughwort or resinous boneset, is a rare North American plant species in the family Asteraceae. Eupatorium resinosum is native to the eastern coastal states of the United States, though with a discontinuous distribution. Some populations grow in the Carolinas, others in New Jersey. It formerly grew in New York and Delaware, but is now apparently extirpated there. There are no reports of the species in Maryland or Virginia in between. Eupatorium resinosum has stems up to 100 cm (40 inches) tall and produce short rhizomes. The inflorescences are composed

Rubus originalis a rare North American species of brambles in the rose family. It has been found in the eastern United States (New Jersey, Maryland, West Virginia, and North Carolina). Nowhere is it common. The genetics of Rubus is extremely complex, so that it is difficult to decide on which groups should be recognized as species. There are many rare species with limited ranges such as this. Further study is suggested to clarify the taxonomy.

Dichanthelium hirstii is a species of grass known by the common name Hirst's panic grass. It is native to the eastern United States, where it is extant in Delaware, New Jersey, and North Carolina. It is extirpated in Georgia. This grass produces small tufts or large clumps of stems which can be up to a meter tall in some areas. The inflorescence is a panicle of small spikelets that grow pressed against the stem. This grass grows in ponds in the Pine Barrens on the coastal plain of New Jersey and on coastal grasslands in North Carolina. When it occurred in Georgia it grew in cypress swamps. It

Sagittaria teres, the quill-leaved arrowhead or slender arrowhead, is an aquatic plant species in the genus Sagittaria. It is a perennial herb up to 80 centimetres (31 inches) tall.

It grows along the shores of lakes, marshes, and

Pyxidanthera barbulata, the flowering pixiemoss, is a species of flowering plant in the family Diapensiaceae. It is native to the eastern United States, occurring on the coast from Long Island to New Jersey and Virginia to South Carolina. Pyxidanthera barbulata is not a moss. It is a low subshrub producing a mat on the ground. It grows from a rhizome and the stems root at intervals where they meet the ground. The crowded leaves are lance-shaped and no more than a centimeter long. The flowers have pink sepals and white petals up to about half a centimeter long. This plant grows in dry, sandy

Pyxidanthera is a genus of flowering plant in the family Diapensiaceae. Though often recognized as two species, Pyxidanthera barbulata and Pyxidanthera brevifolia, these designations are not genetically or morphologically distinct. Furthermore, these two designated species were found to not be reciprocally monophyletic. Despite these findings, some flora still recognize these two species based on their range, habitat, and leaf morphology (size and pubescence). However, these leaf morphology differences are directly related to habitat and moisture. Despite the species designations being based

Bidens bidentoides (formerly Diodonta bidentoides), commonly called swamp beggar's-ticks and delmarva beggarticks, is an annual, herbaceous, flowering plant in the Asteraceae family. It is native to the northeastern and east-central parts of the United States, the coastal plain of the States of Maryland, Delaware, Pennsylvania, and New Jersey plus the region around the Hudson River estuary in New York.

The sterile triploid offspring of mountain spleenwort (A. montanum) and Bradley's spleenwort (A. bradleyi), it is known from a few sites where those species grow together. First collected by Edgar T. Wherry in 1935, it was largely ignored until a new colony was found in 1961, and the species was named in his honor.

Common names for Trollius laxus include American globeflower and American spreading globeflower. The American Globeflower, Trollius laxus is an endangered species of flowering plants Native to Northeastern United States. This species of plants is limited in range by their ability to exclusively survive in wetlands and marshes. Thus, clusters of the species are constantly

Micranthemum micranthemoides (syn. Hemianthus micranthemoides), commonly known as Nuttall's mudflower is an extinct species of subaquatic Micranthemum that previously inhabited wet areas from Virginia to New York. It is commonly misidentified as a similar species, Micranthemum glomeratum, in aquascaping.

Eurybia compacta, commonly known as the slender aster, is an herbaceous perennial native to the eastern United States from New Jersey to Georgia. It is commonly found along the coastal plain in dry sandy soils, especially in pinelands. While it is not considered to be in high danger of extinction, it is of conservation concern and has most likely been extirpated from much of its original range. The slender aster was for a long time considered to be a variety of E. surculosa, but Guy Nesom's recent research within the genus has shown that it is distinct enough to be treated as a species. It

Solidago stricta, commonly known as wand goldenrod or willowleaf goldenrod, is a North American species of goldenrod in the family Asteraceae. A herbaceous perennial dicot it grows in the southern and southeastern United States. It has been described as having a wand like appearance and grows in sandy pine barren and wet coastal plain habitats. It blooms August to November.

Eupatorium godfreyanum, commonly called Godfrey’s thoroughwort, is a North American species of plants in the family Asteraceae. It is found in the east-central United States, primarily from Pennsylvania to North Carolina, with a few isolated populations west of the Appalachians in Ohio, Kentucky, and Tennessee. Chromosomal analysis suggests that E. godfreyanum originated as a hybrid between E. rotundifolium and E. sessilifolium. Eupatorium godfreyanum does, however, reproduce on its own and can be found in areas where neither parent species is present. Thus it deserves full recognition as a

Kalmia buxifolia is a species of flowering plant in the family Ericaceae known by the common name sandmyrtle, or sand-myrtle. It is native to the mid-Atlantic and southeastern United States, where it has a disjunct distribution, occurring in three separate areas. It is known from the Pine Barrens of New Jersey, the Coastal Plain of the Carolinas, and the southeastern Blue Ridge Mountains. This species is sometimes called Leiophyllum buxifolium, the only member of the monotypic genus Leiophyllum. Genetic analysis supports its inclusion in genus Kalmia. This species is quite variable in

Euphorbia purpurea is a species of Euphorbia known by the common names Darlington's glade spurge, glade spurge, and purple spurge. It is native to the Eastern United States, where it occurs from Ohio and Pennsylvania south to North Carolina.
