Epilobium Nivium
''Epilobium nivium'', commonly known as the Snow Mountain willowherb, is a perennial subshrub endemic to the Coast Range Mountains of Northern California. It was originally described based upon a collection from Snow Mountain. Although first described in 1892, as of 2019 the species is known from fewer than 20 small occurrences spread throughout high elevation sites across Colusa, Glenn, Lake, Mendocino, Tehama, and Trinity counties. ''Epilobium nivium'' has a California Rare Plant Rank of 1B.2 (fairly endangered in CA). The California Natural Diversity Database has assigned it a NatureServe rank of G2G3 (globally vulnerable or imperiled). The species is also included on the US Forest Service list of sensitive species. The plant has bee-pollinated flowers and a growth form suggestive of a desert species. Snow Mountain willowherb thrives under extremes. It grows in sites which alternate between hot, dry summer conditions and snow cover in winter. ''Epilobium nivium'' grows in ...

Townshend Stith Brandegee
Townshend Stith Brandegee (February 16, 1843 – April 7, 1925) was an American botanist. He was an authority on the flora of Baja California and the Channel Islands of California, Channel Islands of California. Early life Brandegee was born on February 16, 1843, in Berlin, Connecticut. From 1862 to 1864 he served in the Connecticut Artillery and later decided to become an engineer. He got his degree in engineering from Sheffield Scientific School but then pursued botany after he participated at some classes with Daniel Cady Eaton in Yale University. When he graduated from there, he became a county surveyor and city engineer at Canon City, Colorado where in free time he also collected certain species of plants. He was accustomed with John H. Redfield and Asa Gray the later of which suggested him to join Ferdinand V. Hayden's expedition to southwest Colorado and Utah where he will use his surveyor skills as well as botanical. He was hired as a railroad surveyor in both Arkansas a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Epilobium Nevadense
''Epilobium nevadense'' is a rare and vulnerable species of flowering plant in the willowherb family Onagraceae. It is known from a few scattered populations in mountain ranges in Nevada, Utah, and northwestern Arizona. It grows on talus slopes composed of either volcanic or limestone origin from 5200–9000 feet in elevation. The nearest known relative of Nevada willowherb is Snow Mountain willowherb (''Epilobium nivium ''Epilobium nivium'', commonly known as the Snow Mountain willowherb, is a perennial subshrub endemic to the Coast Range Mountains of Northern California.

These two species together form ''Epilobium'' sect. ''Cordylophorurn'' subsect. ''Petrolobium'' and have been shown to form infertile hybrids in cultivation.Raven, P.

Epilobium
''Epilobium'' is a genus of flowering plants in the family Onagraceae, containing about 197 species. The genus has a worldwide distribution. It is most prevalent in the subarctic, temperate and subantarctic regions, whereas in the subtropics and tropics ''Epilobium'' species are restricted to the cool montane biomes, such as the New Guinea Highlands. The taxonomy of the genus has varied between different botanists, but the modern trend is to include the previously recognised genera ''Boisduvalia'', '' Chamaenerion'' (previously ''Chamerion''), ''Pyrogennema'' and ''Zauschneria'' within ''Epilobium'' according to Peter H. Raven, who has extensively studied the willowherbs and merges the other segregate genera into ''Epilobium''. Fringed willowherb (''Epilobium ciliatum'') is likely a cryptic species complex; apparently these plants also commonly hybridize with their congeners. Most species are known by the common name willowherbs for their willow-like leaves. Those that were on ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Perennial Plants
In horticulture, the term perennial ('' per-'' + '' -ennial'', "through the year") is used to differentiate a plant from shorter-lived annuals and biennials. It has thus been defined as a plant that lives more than 2 years. The term is also loosely used to distinguish plants with little or no woody growth (secondary growth in girth) from trees and shrubs, which are also technically ''perennials''. Notably, it is estimated that 94% of plant species fall under the category of perennials, underscoring the prevalence of plants with lifespans exceeding two years in the botanical world. Perennials (especially small flowering plants) that grow and bloom over the spring and summer, die back every autumn and winter, and then return in the spring from their rootstock or other overwintering structure, are known as herbaceous perennials. However, depending on the rigours of the local climate (temperature, moisture, organic content in the soil, microorganisms), a plant that is a perennial ...

Plants Described In 1892
Plants are the eukaryotes that form the kingdom Plantae; they are predominantly photosynthetic. This means that they obtain their energy from sunlight, using chloroplasts derived from endosymbiosis with cyanobacteria to produce sugars from carbon dioxide and water, using the green pigment chlorophyll. Exceptions are parasitic plants that have lost the genes for chlorophyll and photosynthesis, and obtain their energy from other plants or fungi. Most plants are multicellular organism, multicellular, except for some green algae. Historically, as in Aristotle's biology, the plant kingdom encompassed all living things that were not animals, and included algae and fungi. Definitions have narrowed since then; current definitions exclude fungi and some of the algae. By the definition used in this article, plants form the clade Viridiplantae (green plants), which consists of the green algae and the embryophytes or land plants (hornworts, liverworts, mosses, lycophytes, ferns, conif ...
