Melanthieae is a tribe of flowering plants within the family Melanthiaceae. Molecular phylogenetic studies in the 21st century have resulted in a large-scale reassignment of many of its species to different genera; in particular the genus Zigadenus (deathcamases) has been restricted to a single species, Zigadenus glaberrimus. Plants contain alkaloids, making them unpalatable to grazing animals; many are very poisonous to both animals and humans.
Prunella is a genus of herbaceous plants in the family Lamiaceae, also known as self-heals, heal-all, or allheal for their use in herbal medicine.
Lycopodium clavatum is the most widespread species in the genus Lycopodium in the clubmoss family.
Narthecium ossifragum, commonly known as bog asphodel, Lancashire asphodel or bastard asphodel, is a species of flowering plant in the family Nartheciaceae. It is native to Western Europe, found on wet, boggy moorlands up to about 1,000 m (3,300 ft) in elevation. It produces spikes of bright yellow flowers in summer. The bright orange fruits have been used as a colourant to replace saffron by Shetland Islanders. Despite the plant's English name "bog asphodel", it is not particularly closely related to the true asphodels. In addition to other forms of pollination, this plant is adapted to rain-pollination. The Latin specific name ossifragum means "bone-breaker", and refers to a traditional belief that eating the plant caused sheep to develop brittle bones. The probable origin of this story is that sheep eating a calcium-poor diet are likely to develop bone weakness, and N. ossifragum favours acidic low-calcium soils.
Tofieldiaceae is a family of flowering plants in the monocot order Alismatales. The family is divided into four genera, which together comprise 28 known species. They are small, herbaceous plants, mostly of arctic and subarctic regions, but a few extend further south, and one genus is endemic to northern South America and Florida. Tofieldia pusilla is sometimes grown as an ornamental.
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.
Anthemis arvensis, also known as corn chamomile, mayweed, scentless chamomile, or field chamomile is a species of flowering plant in the genus Anthemis, in the aster family. It is used as an ornamental plant.
NVC community CG10 is one of the calcicolous grassland communities in the British National Vegetation Classification system. Of the upland group of calcicolous grasslands, it is the only one with a short sward associated with heavy grazing.
Lilium columbianum is a lily native to western North America. It is also known as the Columbia lily, Columbia tiger lily, or simply tiger lily.
Papaver radicatum is a species of poppy known by the common names Arctic poppy, rooted poppy, and yellow poppy. It is a flowering plant in the family Papaveraceae.
Butomus is the only known genus in the plant family Butomaceae, native to Europe and Asia. It is considered invasive in some parts of the United States.
Bolboschoenus maritimus is a species of flowering plant from family Cyperaceae. Common names for this species include sea clubrush, cosmopolitan bulrush, alkali bulrush, saltmarsh bulrush, and bayonet grass. It is found in seaside wetland habitats over much of the world. It is widespread across much of temperate and subtropical Africa, Asia, Europe, North America, South America and various islands.
Tofieldia is a small genus of flowering plants described as a genus in 1778. It is widespread across much of Europe, Asia, and North America.
Triantha is a small genus of flowering plants in the family Tofieldiaceae, first described as a genus in 1879. False asphodel is a common name for plants in this genus.
Harperocallis is a genus of flowering plants in the family Tofieldiaceae, native to Florida and northwestern South America. It was originally described as a monotypic genus, based on the Floridian H. flava, in 1968, but was expanded in 2013 to include ten South American species formerly placed in Isidrogalvia.
Triantha racemosa, commonly called the coastal false asphodel or southern bog asphodel, is a species of flowering plant in the Tofieldia family. It is native to the Coastal Plain of the Southeastern United States, although there are a few disjunct populations inland. It is found in acidic wetlands, including wet barrens and savannas.
Triantha glutinosa is a species of flowering plant in the Tofieldiaceae family. It is commonly known as the sticky false asphodel, sticky tofieldia or northern bog asphodel, is a species of flowering plant in the tofieldia family.
Tofieldia calyculata is a species of flowering plant belonging to the family Tofieldiaceae.
Triantha occidentalis, the western false asphodel, is a species of carnivorous flowering plant in the family Tofieldiaceae. It is found in the Pacific Northwest.
Luisierella is a genus of mosses belonging to the family Timmiellaceae.
