Physaria Tenella
''Physaria tenella'' is a species of flowering plant in the family Brassicaceae known by the common names Moapa bladderpod and slender bladderpod. It is native to western North America from Utah to Sonora, where it grows mainly in desert habitat. This is an Annual plant, annual Herbaceous plant, herb producing several hairy multibranched erect to spreading stems sometimes exceeding half a meter long. The basal leaves are up to 6.5 centimeters long and sometimes toothed, and there are smaller leaves higher on the stem. The inflorescence is a raceme of flowers at the tip of the stem. The mustardlike flower has four orange to bright yellow petals each up to a centimeter long. The fruit is a plump, hairy, rounded capsule.

Physaria
''Physaria'' is a genus of flowering plants in the family Brassicaceae. Many species are known generally as twinpods, bladderpods, or lesquerella. They are native to the Americas, with many species endemic to western North America. They are densely hairy annual and perennial herbs often growing prostrate or decumbent, along the ground in patches or clumps. They bear inflorescences of bright yellow flowers. The fruit is often notched deeply, dividing into twin sections, giving the genus its common name. Bladderpod oil is extracted from the seeds of ''Physaria fendleri'' and certain other species in the genus. U.S. Fish and Wildlife Service: Missouri Bladderpod 5-Year Review (2008) Due to the presence of both annual and perennial herbaceous members, this genus has been used as a model for allocation pattern comparisons ...

Leo Lesquereux
Charles Léo Lesquereux (November 18, 1806 – October 25, 1889) was a Swiss-born bryologist and a pioneer of American paleobotany who studied the formation of peat bogs. Career Lesquereux was born in the town of Fleurier, located in the canton of Neuchâtel. Despite the fact Lesquereux lacked formal training in botany, he became a celebrated and much published figure in the field of paleobotany. Until 1827 he took classes at the academy at Neuchâtel, and subsequently worked as a tutor of French language in Eisenach, Germany(at the time Prussia). There he tutored many higher-class individuals, including some children of royalty. Afterwards he returned to Switzerland as a schoolteacher, and later principal at the College of La Chaux-de-Fonds. In 1833 he suffered a total loss of hearing due illness and a fall from a cliff. He attempted to obtained treatment from a noted French otologist Jean-Marc Gaspard Itard but was treated disrespectfully and given painful injections of flu ...

Plantae
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 lost ...

Angiosperms
Flowering plants are plants that bear flowers and fruits, and form the clade Angiospermae (), commonly called angiosperms. They include all forbs (flowering plants without a woody stem), grasses and grass-like plants, a vast majority of broad-leaved trees, shrubs and vines, and most aquatic plants. The term "angiosperm" is derived from the Greek words ἀγγεῖον / ('container, vessel') and σπέρμα / ('seed'), meaning that the seeds are 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 (). Angiosperms are distinguished from the other seed-producing plants, the gymnosperms, by having flowers, xylem consisting of vessel elements instead of tracheids, endosperm within their seeds, and fruits that completely envelop the seeds. The ancestors of flowering plants diverged from the common ances ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Eudicots
The eudicots, Eudicotidae, or eudicotyledons are a clade of flowering plants mainly characterized by having two seed leaves upon germination. The term derives from Dicotyledons. Traditionally they were called tricolpates or non- magnoliid dicots by previous authors. The botanical terms were introduced in 1991 by evolutionary botanist James A. Doyle and paleobotanist Carol L. Hotton to emphasize the later evolutionary divergence of tricolpate dicots from earlier, less specialized, dicots. Numerous familiar plants are eudicots, including many common food plants, trees, and ornamentals. Some common and familiar eudicots include sunflower, dandelion, forget-me-not, cabbage, apple, buttercup, maple, and macadamia. Most leafy trees of midlatitudes also belong to eudicots, with notable exceptions being magnolias and tulip trees which belong to magnoliids, and ''Ginkgo biloba'', which is not an angiosperm.

Rosids
The rosids are members of a large clade (monophyletic group) of flowering plants, containing about 70,000 species In biology, a species is the basic unit of Taxonomy (biology), classification and a taxonomic rank of an organism, as well as a unit of biodiversity. A species is often defined as the largest group of organisms in which any two individuals of ..., more than a quarter of all angiosperms. The clade is divided into 16 to 20 Order (biology), orders, depending upon Circumscription (taxonomy), circumscription and Biological classification, classification. These orders, in turn, together comprise about 140 Family (biology), families. Fossil rosids are known from the Cretaceous period. Molecular clock estimates indicate that the rosids originated in the Aptian or Albian stages of the Cretaceous, between 125 and 99.6 million years ago. Today's forests are highly dominated by rosid species, which in turn helped with diversification in many other living lineages. Additio ...

Brassicales
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 Southw ...

Brassicaceae
Brassicaceae () or (the older) Cruciferae () is a medium-sized and economically important family of flowering plants commonly known as the mustards, the crucifers, or the cabbage family. Most are herbaceous plants, while some are shrubs. The leaves are simple (although are sometimes deeply incised), lack stipules, and appear alternately on stems or in rosettes. The inflorescences are terminal and lack bracts. The flowers have four free sepals, four free alternating petals, two shorter free stamens and four longer free stamens. The fruit has seeds in rows, divided by a thin wall (or septum). The family contains 372 genera and 4,060 accepted species. The largest genera are '' Draba'' (440 species), '' Erysimum'' (261 species), '' Lepidium'' (234 species), '' Cardamine'' (233 species), and '' Alyssum'' (207 species). The family contains the cruciferous vegetables, including species such as '' Brassica oleracea'' (cultivated as cabbage, kale, cauliflower, broccoli and co ...

Sereno Watson
Sereno Watson (December 1, 1826 in East Windsor Hill, Connecticut – March 9, 1892 in Cambridge, Massachusetts) was an American botanist. Graduating from Yale in 1847 in Biology, he drifted through various occupations until, in California, he joined the Clarence King Expedition and eventually became its expedition botanist. Appointed by Asa Gray as assistant in the Gray Herbarium of Harvard University in 1873, he later became its curator, a position he maintained until his death. Watson was elected a Fellow of the American Academy of Arts and Sciences in 1874, and a member of the National Academy of Sciences The National Academy of Sciences (NAS) is a United States nonprofit, non-governmental organization.

Genus
Genus ( plural genera ) is a taxonomic rank used in the biological classification of living and fossil organisms as well as viruses. In the hierarchy of biological classification, genus comes above species and below family. In binomial nomenclature, the genus name forms the first part of the binomial species name for each species within the genus. :E.g. '' Panthera leo'' (lion) and '' Panthera onca'' (jaguar) are two species within the genus ''Panthera''. ''Panthera'' is a genus within the family Felidae. The composition of a genus is determined by taxonomists. The standards for genus classification are not strictly codified, so different authorities often produce different classifications for genera. There are some general practices used, however, including the idea that a newly defined genus should fulfill these three criteria to be descriptively useful: # monophyly – all descendants of an ancestral taxon are grouped together (i.e. phylogenetic analysis should c ...
