Gamochaeta Ustulata
''Gamochaeta ustulata'', commonly named featherweed or Pacific cudweed, is a North American species of flowering plant in the family Asteraceae. It is native to the western United States and southwestern Canada, in British Columbia, Washington, Oregon, and California. It is found primarily on seaside hills and in the Coast Ranges The Pacific Coast Ranges (officially gazetted as the Pacific Mountain System in the United States) are the series of mountain ranges that stretch along the West Coast of North America from Alaska south to Northern and Central Mexico. Although the ..., with additional populations inland. ''Gamochaeta ustulata'' is an annual or perennial herb up to tall. Leaves are up to long, green on the top but appearing white on the underside because of many woolly hairs. The plant forms many small flower heads in elongated arrays. Each head contains 4–6 yellow disc flowers but no ray flowers. References ustulata Flora of the West Coast of the United St ...

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] |
Asteraceae
The family Asteraceae, alternatively Compositae, consists of over 32,000 known species of flowering plants in over 1,900 genera within the order Asterales. Commonly referred to as the aster, daisy, composite, or sunflower family, Compositae were first described in the year 1740. The number of species in Asteraceae is rivaled only by the Orchidaceae, and which is the larger family is unclear as the quantity of extant species in each family is unknown. Most species of Asteraceae are annual, biennial, or perennial herbaceous plants, but there are also shrubs, vines, and trees. The family has a widespread distribution, from subpolar to tropical regions in a wide variety of habitats. Most occur in hot desert and cold or hot semi-desert climates, and they are found on every continent but Antarctica. The primary common characteristic is the existence of sometimes hundreds of tiny individual florets which are held together by protective involucres in flower heads, or more technicall ...

Coast Ranges
The Pacific Coast Ranges (officially gazetted as the Pacific Mountain System in the United States) are the series of mountain ranges that stretch along the West Coast of North America from Alaska south to Northern and Central Mexico. Although they are commonly thought to be the westernmost mountain range of the continental United States and Canada, the geologically distinct Insular Mountains of Vancouver Island lie further west. The Pacific Coast Ranges are part of the North American Cordillera (sometimes known as the Western Cordillera, or in Canada, as the Pacific Cordillera and/or the Canadian Cordillera), which includes the Rocky Mountains, the Columbia Mountains, the Interior Mountains, the Interior Plateau, the Sierra Nevada, the Great Basin mountain ranges, and other ranges and various plateaus and basins. The Pacific Coast Ranges designation, however, only applies to the Western System of the Western Cordillera,S. Holland, ''Landforms of British Columbia'', BC Govt. 197 ...

Gamochaeta
''Gamochaeta'' is a genus of flowering plants in the family Asteraceae. There has not always been agreement among botanists regarding its status as a recognized genus, but it has become more accepted in recent years.Nesom, G. L. 1990. The taxonomic status of ''Gamochaeta'' (Asteraceae: Inuleae) and the species of the United States. ''Phytologia'' 68: 186–198.''Gamochaeta''. Flora of North America. It currently includes many plants that previously belonged in genus ''Gnaphalium''. Like many species of ''Gnaphalium'', many ''Gamochaeta'' are called cudweeds or everlastings. ''Gamochaeta'' are native to North America, North and South America, with one species endemic to Tristan da Cunha in the South Atlantic.Evenhuis, N. L. and L. G. Eldredge, Eds.

Flora Of The West Coast Of The United States
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 Ph ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Plants Described In 1841
Plants are predominantly photosynthetic eukaryotes of the kingdom Plantae. Historically, the plant kingdom encompassed all living things that were not animals, and included algae and fungi; however, all current definitions of Plantae exclude the fungi and some algae, as well as the prokaryotes (the archaea and bacteria). By one definition, plants form the clade Viridiplantae (Latin name for "green plants") which is sister of the Glaucophyta, and consists of the green algae and Embryophyta (land plants). The latter includes the flowering plants, conifers and other gymnosperms, ferns and their allies, hornworts, liverworts, and mosses. Most plants are multicellular organisms. Green plants obtain most of their energy from sunlight via photosynthesis by primary chloroplasts that are derived from endosymbiosis with cyanobacteria. Their chloroplasts contain chlorophylls a and b, which gives them their green color. Some plants are parasitic or mycotrophic and have los ...
