Phegopteris is a genus of ferns in the family Thelypteridaceae, subfamily Phegopteridoideae, in the Pteridophyte Phylogeny Group classification of 2016. They are known collectively as the beech ferns. Species are native to Asia, North America and Europe.
Persicaria is a genus of herbaceous flowering plants in the knotweed family, Polygonaceae. Plants of the genus are known commonly as knotweeds or smartweeds. It has a cosmopolitan distribution, with species occurring nearly worldwide. The genus was segregated from Polygonum.
Melanthiaceae, also called the bunchflower family, is a family of flowering herbaceous perennial plants native to the Northern Hemisphere. Along with many other lilioid monocots, early authors considered members of this family to belong to the family Liliaceae, in part because both their sepals and petals closely resemble each other and are often large and showy like those of lilies, while some more recent taxonomists have placed them in a family Trilliaceae. The most authoritative modern treatment, however, the APG III system of 2009, places the family in the order Liliales, in the clade monocots. Circumscribed in this way, the family includes up to 17 genera.
Arundinaria, commonly known as canes, is a genus of bamboo in the grass family.
Heracleum maximum, commonly known as cow parsnip, is the only member of the genus Heracleum native to North America. It is also known as American cow-parsnip, Indian celery, Indian rhubarb or pushki. It is sometimes referred to as Heracleum lanatum, which is regarded as a synonym.
Clintonia is a genus of flowering plants in the family Liliaceae. Plants of the genus are distributed across the temperate regions of North America and eastern Asia in the mesic understory of deciduous or coniferous forests. The genus was first described by Rafinesque in 1818. It was named for DeWitt Clinton (1769–1828), a naturalist and politician from the U.S. state of New York.
Cardamine is a large genus of flowering plants in the mustard family, Brassicaceae, known as bittercresses and toothworts. It contains more than 200 species of annuals and perennials. Species in this genus can be found worldwide, except the Antarctic, in diverse habitats. The name Cardamine is derived from the Greek kardamon, cardamom, an unrelated plant in the ginger family, used as a pungent spice in cooking.
Polygonum is a genus of about 130 species of flowering plant in the buckwheat and knotweed family Polygonaceae. Common names include knotweed and knotgrass. In the Middle English glossary of herbs Alphita, it was known as ars-smerte. There have been various opinions about how broadly the genus should be defined. For example, buckwheat has sometimes been included in the genus as Polygonum fagopyrum. Former genera such as Polygonella have been subsumed into Polygonum; other genera have been split off.
Oryzopsis is a genus of Chinese and North American plants in the grass family. Species from this genus are commonly called ricegrass.
Digitaria is a genus of plants in the grass family native to tropical and warm temperate regions but can occur in tropical, subtropical, and cooler temperate regions as well. Common names include crabgrass, finger-grass, and fonio. They are slender monocotyledonous annual and perennial lawn, pasture, and forage plants; some are often considered lawn pests. Digitus is the Latin word for "finger", and they are distinguished by the long, finger-like inflorescences they produce.
Desmodium is a genus in the flowering plant family Fabaceae, sometimes called tick-trefoil, tick clover, hitch hikers or beggar lice. There are dozens of species and the delimitation of the genus has shifted much over time.
Claytonia is a genus of flowering plants native to North America, Central America, and Asia. The genus was formerly included in Portulacaceae but is now classified in the family Montiaceae, primarily native to the mountain chains of Asia and North America, with a couple of species extending south to Guatemala in Central America, and northwest to Kazakhstan, Mongolia, and Russia in eastern Asia.
Lippia is a genus of flowering plants in the verbena family, Verbenaceae. It was named after Augustus Lippi, (1678-1705), a French naturalist and botanist. He was killed in Abyssinia. The genus contains roughly 200 species of tropical shrubs that are found around the world. Plants are fragrant due to their essential oils, which vary between species but may include estragole, carvacrol, linalool, or limonene. The leaves of certain species, such as L. graveolens, can be used as a culinary herb similar to oregano.
Lycopus is a genus in the family Lamiaceae. They are all herbaceous plants native to Europe, Asia, Australia, and North America. The species are most often found in wetlands, damp meadows, and stream banks. Some of the wetland species have become endangered.
Disporum is a genus of about 20 species of perennial flowering plants, found in Asia from northern India to Japan, south to Indonesia and north into the Russian Far East.
Eleocharis is a virtually cosmopolitan genus of 250 or more species of flowering plants in the sedge family, Cyperaceae. The name is derived from the Greek words ἕλειος (heleios), meaning "marsh dweller," and χάρις (charis), meaning "grace." Members of the genus are known commonly as spikerushes or spikesedges. The genus has a geographically cosmopolitan distribution, with centers of diversity in the Amazon Rainforest and adjacent eastern slopes of the South American Andes, northern Australia, eastern North America, California, Southern Africa, and subtropical Asia. The vast majority of Eleocharis species grow in aquatic or mesic habitats from sea level to higher than 5,000 meters in elevation.
Pycnanthemum is a genus of plants in the mint family (Lamiaceae). They are commonly known as mountain mints, though "the mountain mint" may also be any locally common species in particular. Some are known as koellias, after an obsolete genus name.
Hylodesmum glutinosum is a species of flowering plant in the family Fabaceae. Common names include large tick-trefoil, clustered-leaved tick-trefoil, large-flowered tick-clover, pointed tick-trefoil, beggar's lice and pointed-leaved tick-trefoil. It occurs in eastern Canada, the central and eastern United States, and northeastern Mexico.
Carex lupulina, known as hop sedge or common hop sedge, is a species of sedge native to most of eastern North America.
