Meadowfoam
''Limnanthes'', the type genus of the family Limnanthaceae, consists of annual herbaceous plants commonly known as the meadowfoams. The seven species are all native to coastal and adjoining regions (inland valleys, foothills and mountains) of western North America, where they typically grow in marshy habitats, such as the margins of vernal pools. Some are endemic to California. General form ranges from decumbent to erect, with leaves either pinnately lobed or compound; the lobes or leaflets may themselves range from entire to deeply lobed. Both 4- and 5-sepaled and petaled members are known. The white meadowfoam ''Limnanthes alba'' is of commercial interest for its oil, while several other species are rare or endangered. Honey produced by bees that pollinate ''Limnanthes alba'' has the distinct flavor of toasted marshmallows. ''L. douglasii'' is widely cultivated as a hardy annual Annual may refer to: *Annual publication, periodical publications appearing regularly once pe ...

Limnanthes Floccosa
''Limnanthes floccosa'', or woolly meadowfoam, is a species of meadowfoam found in Northern California and Southern Oregon, in the United States. Most of the subspecies have highly restricted distributions and are listed as critical or endangered. Perhaps the most familiar subspecies of woolly meadowfoam is ''californica'', not because it is the one most often seen (it is very inconspicuous), but because this taxon has been the focus of a significant conflict. The subspecies is found only among a dozen or so populations in Butte County, California, and is legally protected as endangered. Conflict has arisen between those who would protect the few remaining populations and those who would rather use its critical habitat for economic activities. Certain subspecies of ''L. floccosa'' have been used to improve a meadowfoam cultivar derived from ''Limnanthes alba''. The crop is grown for its seed oil, which contains long chain fatty acids (greater than 20 carbons), has high oxidative ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Limnanthes Vinculans
''Limnanthes vinculans'', the Sebastopol meadowfoam, is an endangered species of meadowfoam found only in the Laguna de Santa Rosa in Sonoma County, California, United States and an area slightly to the south in the Americano Creek and Washoe Creek watersheds. The name ''vinculans'' derives from the Latin root vinculum, meaning "a bond, a cord." The specific epithet ''vinculans'' means linking or bonding, in reference to the sharing of some characters of ''L. vinculans'' with ''L. douglasii'' (R.Br) and ''L. bakeri'' (J.T. Howell). Description Like the other meadowfoams, ''Limnanthes vinculans'' is a small annual herb, with multiple stems growing up to in height; white flowers occur singly at the ends of stems. This plant bears white flowers singly at the termini of its stems. ''L. vinculans'' is unique in its genus for having compound leaves with three to five leaflets; each leaflet is entire, with a narrow-obovate shape. The flowers are small (12 to 18 millimeters across), ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
White Meadowfoam
''Limnanthes alba'' is a species of flowering plant in the meadowfoam family known by the common name white meadowfoam. It is native to California and Oregon, where it grows in wet grassy habitat, such as vernal pools and moist spots in woodlands. It generally grows in poorly drained soils. It is an annual herb producing an erect or decumbent stem up to about 30 centimeters long. The leaves divided into several lobed or unlobed leaflets. The flower is cup-shaped with white petals 1 to 1.5 centimeters long. This grassland wildflower is also under small-scale cultivation. It is the source of meadowfoam seed oil and The fruit of the plant, a nutlet, is 20 to 30% oil. The oil is one of the most stable vegetable oils known and can be converted to waxes and lubricants, similar to whale oil.

Limnanthes Douglasii
''Limnanthes douglasii'' is a species of annual flowering plant in the family Limnanthaceae (meadowfoam) commonly known as Douglas' meadowfoam or poached egg plant. It is native to California and Oregon, where it grows in wet, grassy habitat, such as vernal pools and spring meadows. It can grow in poorly drained clay soils. The plant was collected by the Scottish explorer and botanist David Douglas, who worked on the west coast of America in the 1820s. The plant usually bears white flowers with yellow centers, hence the name "poached egg plant", but flower color can vary across subspecies. It is a popular ornamental plant. It attracts hoverflies and is pollinated by bees. It is self-seeding, even in a lawn. This plant has gained the Royal Horticultural Society's Award of Garden Merit. There are six subspecies: *''L. douglasii'' subsp. ''douglasii'' R. Br., is native to the coastal mountains and valleys of southwestern Oregon south to the San Francisco Bay Area The San Fra ...

Brassicales Genera
The Brassicales (or Cruciales) are an order of flowering plants, belonging to the eurosids II group of dicotyledons under the APG II system. One character common to many members of the order is the production of glucosinolate (mustard oil) compounds. Most systems of classification have included this order, although sometimes under the name Capparales (the name chosen depending on which is thought to have priority). The order typically contains the following families: * Akaniaceae – two species of turnipwood trees, native to Asia and eastern Australia * Bataceae – salt-tolerant shrubs from America and Australasia * Brassicaceae – mustard and cabbage family; may include the Cleomaceae * Capparaceae – caper family, sometimes included in Brassicaceae * Caricaceae – papaya family * Cleomaceae * Gyrostemonaceae – several genera of small shrubs and trees endemic to temperate parts of Australia * Koeberliniaceae – one species of thorn bush native to Mexico and the US Sout ...

Robert Brown (botanist, Born 1773)
Robert Brown (21 December 1773 – 10 June 1858) was a Scottish botanist and paleobotanist who made important contributions to botany largely through his pioneering use of the microscope. His contributions include one of the earliest detailed descriptions of the cell nucleus and cytoplasmic streaming; the observation of Brownian motion; early work on plant pollination and fertilisation, including being the first to recognise the fundamental difference between gymnosperms and angiosperms; and some of the earliest studies in palynology. He also made numerous contributions to plant taxonomy, notably erecting a number of plant families that are still accepted today; and numerous Australian plant genera and species, the fruit of his exploration of that continent with Matthew Flinders. Early life Robert Brown was born in Montrose on 21 December 1773, in a house that existed on the site where Montrose Library currently stands. He was the son of James Brown, a minister in the ...

Hardiness (plants)
Hardiness of plants describes their ability to survive adverse growing conditions. It is usually limited to discussions of climatic adversity. Thus a plant's ability to tolerate cold, heat, drought, flooding, or wind are typically considered measurements of hardiness. Hardiness of plants is defined by their native extent's geographic location: longitude, latitude and elevation. These attributes are often simplified to a hardiness zone. In temperate latitudes, the term most often describes resistance to cold, or "cold-hardiness", and is generally measured by the lowest temperature a plant can withstand. Hardiness of a plant is usually divided into two categories: tender, and hardy. (Some sources also use the erroneous terms "Half-hardy" or "Fully hardy".) Tender plants are those killed by freezing temperatures, while hardy plants survive freezing—at least down to certain temperatures, depending on the plant. "Half-hardy" is a term used sometimes in horticulture to describe bed ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Annual Plant
An annual plant is a plant that completes its life cycle, from germination to the production of seeds, within one growing season, and then dies. The length of growing seasons and period in which they take place vary according to geographical location, and may not correspond to the four traditional seasonal divisions of the year. With respect to the traditional seasons, annual plants are generally categorized into summer annuals and winter annuals. Summer annuals germinate during spring or early summer and mature by autumn of the same year. Winter annuals germinate during the autumn and mature during the spring or summer of the following calendar year. One seed-to-seed life cycle for an annual plant can occur in as little as a month in some species, though most last several months. Oilseed rapa can go from seed-to-seed in about five weeks under a bank of fluorescent lamps. This style of growing is often used in classrooms for education. Many desert annuals are therophytes, be ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
