Sidalcea Hendersonii
''Sidalcea hendersonii'' is a species of flowering plant in the mallow family known by the common name Henderson's checker-mallow. It is native to the Pacific Northwest region of North America. It is named for Oregon botanist Dr. Louis Forniquet Henderson (1853–1942), who was a professor at the University of Oregon. Distribution Occurs in coastal areas spanning from southern Oregon to Vancouver Island and mainland British Columbia. Its range follows the coastline; it grows in tidal marshes and meadows. Extremely rare in Oregon, uncommon in Washington, and rare in British Columbia. Description ''Sidalcea hendersonii'' is a taprooted perennial herb that grows from thick and stubby rhizomes. It has a basal rosette of toothed basal leaves. Stems are erect and hollow, and typically tinged purple. Flowers are five-petaled and numerous, typically fifty or more per plant, forming in branched raceme A raceme ( or ) or racemoid is an unbranched, indeterminate type of infloresce ...

Flowering Plant
Flowering plants are plants that bear flowers and fruits, and form the clade Angiospermae (), commonly called angiosperms. The term "angiosperm" is derived from the Greek words ('container, vessel') and ('seed'), and refers to those plants that produce their seeds enclosed within a fruit. They are by far the most diverse group of land plants with 64 orders, 416 families, approximately 13,000 known genera and 300,000 known species. Angiosperms were formerly called Magnoliophyta (). Like gymnosperms, angiosperms are seed-producing plants. They are distinguished from gymnosperms by characteristics including flowers, endosperm within their seeds, and the production of fruits that contain the seeds. The ancestors of flowering plants diverged from the common ancestor of all living gymnosperms before the end of the Carboniferous, over 300 million years ago. The closest fossil relatives of flowering plants are uncertain and contentious. The earliest angiosperm fossils ar ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Washington (state)
Washington (), officially the State of Washington, is a state in the Pacific Northwest region of the Western United States. Named for George Washington—the first U.S. president—the state was formed from the western part of the Washington Territory, which was ceded by the British Empire in 1846, by the Oregon Treaty in the settlement of the Oregon boundary dispute. The state is bordered on the west by the Pacific Ocean, Oregon to the south, Idaho to the east, and the Canadian province of British Columbia to the north. It was admitted to the Union as the 42nd state in 1889. Olympia is the state capital; the state's largest city is Seattle. Washington is often referred to as Washington state to distinguish it from the nation's capital, Washington, D.C. Washington is the 18th-largest state, with an area of , and the 13th-most populous state, with more than 7.7 million people. The majority of Washington's residents live in the Seattle metropolitan area, the center of trans ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Flora Of British Columbia
Flora is all the plant life present in a particular region or time, generally the naturally occurring (indigenous) native plants. Sometimes bacteria and fungi are also referred to as flora, as in the terms '' gut flora'' or '' skin flora''. Etymology The word "flora" comes from the Latin name of Flora, the goddess of plants, flowers, and fertility in Roman mythology. The technical term "flora" is then derived from a metonymy of this goddess at the end of the sixteenth century. It was first used in poetry to denote the natural vegetation of an area, but soon also assumed the meaning of a work cataloguing such vegetation. Moreover, "Flora" was used to refer to the flowers of an artificial garden in the seventeenth century. The distinction between vegetation (the general appearance of a community) and flora (the taxonomic composition of a community) was first made by Jules Thurmann (1849). Prior to this, the two terms were used indiscriminately.Thurmann, J. (1849). ''Essai de ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Sidalcea
''Sidalcea'' is a genus (approx. 25 species) of the botanical family Malvaceae. It contains several species of flowering plants known generally as checkerblooms or checkermallows, or prairie mallows in the United Kingdom. They can be annuals or perennials, some rhizomatous. They are native to West and Central North America. In mid- to late summer the clumps of toothed basal leaves produce erect flowering stems, with 5-petalled mallow-type flowers in terminal racemes, in shades of pink, white and purple. ''Sidalcea'' is generally diploid (2n = 20), but polyploidy (4n, 6n) also occurs. Annuality appears to have evolved multiple times (4+) within this genus, although an ancestral annual state with annual paraphyly is also possible. Further, evolution rates within annual ''Sidalcea'' lineages appear to be faster than those of perennial lineages, at least when examining nuclear ribosomal DNA (internal and external transcribed spacer regions). Selected species: (A = annual, P = pe ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
NatureServe
NatureServe, Inc. is a non-profit organization based in Arlington County, Virginia, US, that provides proprietary wildlife conservation-related data, tools, and services to private and government clients, partner organizations, and the public. NatureServe reports being "headquartered in Arlington, Virginia, with regional offices in four U.S. locations and in Canada."

Umpqua River
The Umpqua River ( ) on the Pacific coast of Oregon in the United States is approximately long. One of the principal rivers of the Oregon Coast and known for bass and shad, the river drains an expansive network of valleys in the mountains west of the Cascade Range and south of the Willamette Valley, from which it is separated by the Calapooya Mountains. From its source northeast of Roseburg, the Umpqua flows northwest through the Oregon Coast Range and empties into the Pacific at Winchester Bay. The river and its tributaries flow almost entirely within Douglas County, which encompasses most of the watershed of the river from the Cascades to the coast. The "Hundred Valleys of the Umpqua" form the heart of the timber industry of southern Oregon, generally centered on Roseburg. The Native Americans in the Umpqua's watershed consist of several tribes, such as the Lower and Upper Umpqua (for which the river is named), and the Kalapuya. These tribes witnessed much of the Great Flo ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Raceme
A raceme ( or ) or racemoid is an unbranched, indeterminate type of inflorescence bearing flowers having short floral stalks along the shoots that bear the flowers. The oldest flowers grow close to the base and new flowers are produced as the shoot grows in height, with no predetermined growth limit. Examples of racemes occur on mustard (genus ''Brassica'') and radish (genus ''Raphanus'') plants. Definition A ''raceme'' or ''racemoid'' is an unbranched, indeterminate type of inflorescence bearing pedicellate flowers (flowers having short floral stalks called ''pedicels'') along its axis. In botany, an ''axis'' means a shoot, in this case one bearing the flowers. In indeterminate inflorescence-like racemes, the oldest flowers grow close to the base and new flowers are produced as the shoot grows in height, with no predetermined growth limit. A plant that flowers on a showy raceme may have this reflected in its scientific name, e.g. the species ''Cimicifuga racemosa''. A compou ...

Meadow
A meadow ( ) is an open habitat, or field, vegetated by grasses, herbs, and other non-woody plants. Trees or shrubs may sparsely populate meadows, as long as these areas maintain an open character. Meadows may be naturally occurring or artificially created from cleared shrub or woodland. They can occur naturally under favourable conditions (see perpetual meadows), but they are often maintained by humans for the production of hay, fodder, or livestock. Meadow habitats, as a group, are characterized as "semi-natural grasslands", meaning that they are largely composed of species native to the region, with only limited human intervention. Meadows attract a multitude of wildlife, and support flora and fauna that could not thrive in other habitats. They are ecologically important as they provide areas for animal courtship displays, nesting, food gathering, pollinating insects, and sometimes sheltering, if the vegetation is high enough. There are multiple types of meadows, in ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Malvaceae
Malvaceae, or the mallows, is a family of flowering plants estimated to contain 244 genera with 4225 known species. Well-known members of economic importance include okra, cotton, cacao and durian. There are also some genera containing familiar ornamentals, such as ''Alcea'' (hollyhock), ''Malva'' (mallow), and ''Tilia'' (lime or linden tree). The largest genera in terms of number of species include ''Hibiscus'' (300 species), ''Sterculia'' (250 species), ''Dombeya'' (250 species), '' Pavonia'' (200 species) and '' Sida'' (200 species). Taxonomy and nomenclature The circumscription of the Malvaceae is controversial. The traditional Malvaceae '' sensu stricto'' comprise a very homogeneous and cladistically monophyletic group. Another major circumscription, Malvaceae ''sensu lato'', has been more recently defined on the basis that genetics studies have shown the commonly recognised families Bombacaceae, Tiliaceae, and Sterculiaceae, which have always been considered closely allie ...

Tidal Marsh
A tidal marsh (also known as a type of "tidal wetland") is a marsh found along rivers, coasts and estuaries which floods and drains by the tidal movement of the adjacent estuary, sea or ocean. Tidal marshes are commonly zoned into lower marshes (also called intertidal marshes) and upper or high marshes, based on their elevation above sea level. A middle marsh zone also exists for tidal freshwater marshes. Tidal marshes may be further classified into back-barrier marshes, estuarine brackish marshes and tidal freshwater marshes, depending on the influence of sea level. Coastal Coastal tidal marshes are found within coastal watersheds and encompass a variety of types including fresh and salt marshes, bottomland hardwood swamps, mangrove swamps, and palustrine wetlands. Island and barrier island Tidal Marshes also form between a main shoreline and barrier islands. These elongated shifting landforms evolve parallel and in close proximity to the shoreline of a tidal marsh. Many becom ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
British Columbia
British Columbia (commonly abbreviated as BC) is the westernmost province of Canada, situated between the Pacific Ocean and the Rocky Mountains. It has a diverse geography, with rugged landscapes that include rocky coastlines, sandy beaches, forests, lakes, mountains, inland deserts and grassy plains, and borders the province of Alberta to the east and the Yukon and Northwest Territories to the north. With an estimated population of 5.3million as of 2022, it is Canada's third-most populous province. The capital of British Columbia is Victoria and its largest city is Vancouver. Vancouver is the third-largest metropolitan area in Canada; the 2021 census recorded 2.6million people in Metro Vancouver. The first known human inhabitants of the area settled in British Columbia at least 10,000 years ago. Such groups include the Coast Salish, Tsilhqotʼin, and Haida peoples, among many others. One of the earliest British settlements in the area was Fort Victoria, established ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
