Boechera (rockcress) is a genus of the family Brassicaceae. It was named after the Danish botanist Tyge W. Böcher (1909–1983), who was known for his research in alpine plants, including the mustards Draba and Boechera holboellii. According to recent molecular-based studies, Boechera is closely related to the genus Arabidopsis which also includes the widely known model plant Arabidopsis thaliana. Until recently, members of this genus were included in the genus Arabis, but have been separated from that genus based on recent genetic and cytological data. Unlike the genus Arabis (x=8) Boechera

Schoenoplectus acutus (syn. Scirpus acutus, Schoenoplectus lacustris, Scirpus lacustris subsp. acutus), called tule , common tule, hardstem tule, tule rush, hardstem bulrush, or viscid bulrush, is a giant species of sedge in the plant family Cyperaceae, native to freshwater marshes all over North America. The common name derives from the Nāhuatl word tōllin [ˈtoːlːin], and it was first recognized by the early Spanish explorers and missionaries in New Spain who saw the marsh plants in the Central Valley of California as similar to those in the marshes around Mexico City being used to construct

Packera is a genus of about 75 species of plants in the daisy family, Asteraceae. Most species are commonly called ragworts or grounsels. Its members were previously included in the genus Senecio (where they were called aureoid senecios by Asa Gray) but were moved to genus Packera based on chromosome numbers, a variety of morphological characters, and molecular phylogenetic evidence.

Phlegmariurus squarrosus is a species of lycophyte in the family Lycopodiaceae. The genus Phlegmariurus is accepted in the Pteridophyte Phylogeny Group classification of 2016 (PPG I), but not in other classifications, which submerge the genus in Huperzia, with this species as Huperzia squarrosa. The species has a wide distribution from the west Indian Ocean, through tropical and subtropical Asia to eastern Australia and the Pacific.

Boechera holboellii, or Holbøll's rockcress, is a species of plant in the family Brassicaceae. Its cytology has been much studied by the Danish botanist Tyge W. Böcher. Circumscription of this species has varied, with earlier works treating it as a widespread, polymorphic species with several varieties, while more recently it has been treated as a much more narrowly defined species from Greenland. The rust fungus Puccinia monoica infects the plant leading to pseudoflowers, which mimic those of yellow, early spring wildflowers (e.g. buttercups), not only in visible light but also in

Symphyotrichum laeve (formerly Aster laevis) is a flowering plant native to Canada, the United States, and Coahuila (Mexico). It has the common names of smooth blue aster, smooth aster, smooth-leaved aster, glaucous Michaelmas-daisy and glaucous aster.

Symphyotrichum lateriflorum (formerly Aster lateriflorus) is a species of flowering plant in the aster family (Asteraceae). Commonly known as calico aster, starved aster, and white woodland aster, it is native to eastern and central North America. It is a perennial and herbaceous plant that may reach heights up to 120 centimeters (4 feet) and widths up to 30 centimeters (1 foot). The flowers of calico aster are small compared to most Symphyotrichum species. They have an average of 7–15 short white ray florets, which are rarely tinted pink or purple. The flower centers, composed of disk

Carex boecheriana, Böcher's sedge, is a species of sedge in the family Cyperaceae, native to Greenland. It grows in chalky, salty soils on both sides of the island. It is a fairly tall sedge, growing to a height of 20–40 cm (8–20 in). It is a host of the smut fungus Anthracoidea capillaris.

Almutaster is a North American genus of plants in the family Asteraceae containing the single species Almutaster pauciflorus (formerly Aster pauciflorus), which is known by the common name alkali marsh aster. It is native to Canada (Northwest Territories and the three Prairie Provinces), the Western United States, and northern and central Mexico (as far south as Tlaxcala). The genus is named for botanist Almut Gitter Jones. Almutaster pauciflorus grows in wet alkaline and saline soils such as inland salt marshes and salt flats. This is a perennial herb growing a reddish-green glandular stem

Packera aurea (formerly Senecio aureus), commonly known as golden ragwort or simply ragwort, is a perennial flower in the family Asteraceae. It is also known as golden groundsel, squaw weed, life root, golden Senecio, uncum, uncum root, waw weed, false valerian, cough weed, female regulator, cocash weed, ragweed, staggerwort, and St. James wort. It is native to eastern North America, from Labrador to Minnesota and from North Carolina to Arkansas (with additional populations in the panhandle of Florida).

Bryoxiphium madeirense is a species of moss in the Bryoxiphiaceae family. It is endemic to the Island of Madeira in the North Atlantic, part of Portugal.

Boechera retrofracta is a species of flowering plant in family Brassicaceae. The common names include reflexed rockcress.

Triglochin gaspensis (common name - Gaspé Peninsula arrow grass) is a species of flowering plant in the family Juncaginaceae, native to eastern Canada (New Brunswick, Newfoundland island, Nova Scotia, Prince Edward Island and Quebec), and Maine in the north-eastern United States, where it is found growing in the tidal zone of the Atlantic coast below the high-water mark. It was first described by Helmut Lieth and Doris Löve in 1961.

Symphyotrichum puniceum (formerly Aster puniceus), is a species of flowering plant in the family Asteraceae native to eastern North America. It is commonly known as purplestem aster, red-stalk aster, red-stemmed aster, red-stem aster, and swamp aster. It also has been called early purple aster, cocash, swanweed, and meadow scabish. Its range extends from the edges of the Great Plains to the Atlantic coast, and from the Gulf coast of Texas north to southern Ungava Bay in the north of Quebec. It is adventive in Europe.

Myriopteris covillei, commonly known as Coville's lip fern, is a small fern found in the southwestern United States and on the Baja California peninsula, with an outlying population in southern Oregon. Its leaves grow in clusters and are dissected into beadlike segments; the undersides of the leaf axes are covered with whitish scales that conceal the green tissue of the leaf. One of the cheilanthoid lip ferns, it was usually classified in the genus Cheilanthes as Cheilanthes covillei until 2013, when the genus Myriopteris was again recognized as separate from Cheilanthes. The species usually
