Genus is a taxonomic rank above species and below family as used in the biological classification of living and fossil organisms as well as viruses. In binomial nomenclature, the genus name forms the first part of the binomial species name for each species within the genus.
Amygdaloideae is a subfamily within the flowering plant family Rosaceae. It was formerly considered by some authors to be separate from Rosaceae, and the family names Prunaceae and Amygdalaceae have been used. Reanalysis from 2007 has shown that the previous definition of subfamily Spiraeoideae was paraphyletic. To solve this problem, a larger subfamily was defined that includes the former Amygdaloideae, Spiraeoideae, and Maloideae. This subfamily, however, is to be called Amygdaloideae rather than Spiraeoideae under the International Code of Nomenclature for algae, fungi, and plants as updated in 2011.
The International Union for Conservation of Nature (IUCN) Red List of Threatened Species, also known as the IUCN Red List or Red Data Book, founded in 1964, is an inventory of the global conservation status and extinction risk of biological species. A series of Regional Red Lists, which assess the risk of extinction to species within a political management unit, are also produced by countries and organizations.
Quercus garryana is an oak tree species of the Pacific Northwest, with a range stretching from southern California to southwestern British Columbia. It is commonly known as the Garry Oak, Oregon white oak or Oregon oak. It grows from sea level to an altitude of 690 feet in the northern part of its range, and from 980 to 5,900 ft in the south of the range in California. The eponymous Nicholas Garry was deputy governor of the Hudson's Bay Company.
A threatened species is any species which is vulnerable to extinction in the near future. Species that are threatened are sometimes characterised by the population dynamics measure of critical depensation, a mathematical measure of biomass related to population growth rate. This quantitative metric is one method of evaluating the degree of endangerment without direct reference to human activity.
Persicaria maculosa is an annual plant in the buckwheat family, Polygonaceae. Common names include lady's thumb, spotted lady's thumb, Jesusplant, and redshank. It is widespread across Eurasia from Iceland south to Portugal and east to Japan. It is also present as an introduced and invasive species in North America, where it was first noted in the Great Lakes region in 1843 and has now spread through most of the continent.
Yucca elata is a perennial plant, with common names that include soaptree, soaptree yucca, soapweed, and palmella. It is native to southwestern North America, in the Sonoran Desert and Chihuahuan Desert in the United States, southern Nevada, southwestern Utah, and northern Mexico. Yucca elata is widely distributed, although its population appears to be decreasing.
Oemleria cerasiformis, a shrub commonly known as osoberry,Squaw plum, or Indian plum, is the sole extant species in genus Oemleria. The species is native to the Pacific coast and coast ranges of North America, from British Columbia, Canada to Santa Barbara County, California, U.S.A., it is among the first plants to leaf out and flowers early in the spring. It reaches a height of 1.5–5 m (4.9–16.4 ft) and has lance-shaped leaves 5–12 cm (2.0–4.7 in) long. The fruits of osoberry are edible and resemble small plums which are dark blue when ripe. Indigenous peoples of the Americas include osoberry in their diets, make tea of the bark, and chew its twigs to use as a mild anesthetic and aphrodisiac. One other fossil species is known from the genus, Oemleria janhartfordae from the Eocene Klondike Mountain Formation.
Guettarda is a plant genus in the family Rubiaceae. Most of these plants are known by the common name velvetseed.
Macropanax maingayi is a tree in the family Araliaceae.
Beilschmiedia bancroftii is a tree species in the family Lauraceae. It is native to Queensland in Australia. Common names include yellow walnut, yellow nut and canary ash.
Paraseptis is a monotypic moth genus in the family Noctuidae erected by Tomas Mustelin and Lars G. Crabo in 2015. Its only species, Paraseptis adnixa, was first described by Augustus Radcliffe Grote in 1880. It is widely distributed along the Pacific Coast from northern Mexico to south-western British Columbia in a variety of forested habitats.
Trillium angustipetalum, with the common name is narrowpetal wakerobin, is a species of Trillium, plants which may be included within the Liliaceae or the newer family Melanthiaceae.
Halesia carolina, commonly called Carolina silverbells or little silverbells, is a species of flowering plant in the family Styracaceae, native to the southeastern United States.
Nothorites is a monotypic genus in the macadamia family Proteaceae. The sole species, Nothorites megacarpus, is endemic to the wet tropics rain forests of northeastern Queensland, Australia.
Tabernaemontana pandacaqui, known as windmill bush and banana bush, is a species of plant in the dogbane family Apocynaceae.
Nepenthes tboli is a tropical pitcher plant native to the Philippines. The type specimen was collected in 1993 around Lake Parker, T'Boli, South Cotabato, Mindanao, at 1,463 m (4,800 ft) above sea level.
Nepenthes parvula is a tropical pitcher plant native to the Cape York Peninsula of Queensland, Australia.
Hypericum fissurale, known as cracked St. John's wort, is a flowering plant in the St. Johns's wort family (Hypericaceae) endemic to northeastern Turkey. It is considered critically endangered on the IUCN Red List due to its very limited distribution and declining population. It was first formally named by Jurij Nikolaewitch Woronow in 1912. It is a small perennial herb in the section Hypericum sect. Taeniocarpium, reaching around 22 cm (8.7 in) in height. Like most Hypericum species, it has flowers with five yellow petals and numerous stamens. Hypericum fissurale is closely related to Hypericum armenum.
Landiopsis is a monotypic genus of flowering plants belonging to the family Rubiaceae. It only contains one known species, Landiopsis capuronii.
