Primula Sect. Dodecatheon
''Primula'' sect. ''Dodecatheon'' is a section of herbaceous flowering plants in the family Primulaceae. ''Primula'' species in this section were formerly placed in a separate genus, ''Dodecatheon''. The species have basal clumps of leaves and nodding flowers that are produced at the top of tall stems rising from where the leaves join the crown. The genus is largely confined to North America and part of northeastern Siberia. Common names include shooting star, American cowslip, mosquito bills, mad violets, and sailor caps. A few species are grown in gardens for their showy and unique flower display. The stamens are thrust out with the sepals bent back. The flowers are pollinated by bees, which grab hold of the petals, and gather pollen by vibrating the flowers by buzzing their wings ( buzz pollination). The vibration releases pollen from the anthers. Taxonomy Carl Linnaeus created the genus ''Dodecatheon'' in ''Species Plantarum'' in 1753. ''Dodecatheon'' could be distinguis ...

Primula Pauciflora
''Primula pauciflora'', the pretty shooting star, few-flowered shooting star, dark throat shooting star or prairie shooting star, is a species of flowering plant in the primula family Primulaceae. It is a widespread and very variable species, native to western North America, from Subarctic America to Mexico, often in xeric (extremely dry) and desert habitats. It is found in the Great Basin Deserts and Mojave Desert. Its synonyms include ''Dodecatheon pauciflorum'' and ''Dodecatheon pulchellum''.

Carl Linnaeus
Carl Linnaeus (; 23 May 1707 – 10 January 1778), also known after his ennoblement in 1761 as Carl von Linné Blunt (2004), p. 171. (), was a Swedish botanist, zoologist, taxonomist, and physician who formalised binomial nomenclature, the modern system of naming organisms. He is known as the "father of modern taxonomy". Many of his writings were in Latin; his name is rendered in Latin as and, after his 1761 ennoblement, as . Linnaeus was born in Råshult, the countryside of Småland, in southern Sweden. He received most of his higher education at Uppsala University and began giving lectures in botany there in 1730. He lived abroad between 1735 and 1738, where he studied and also published the first edition of his ' in the Netherlands. He then returned to Sweden where he became professor of medicine and botany at Uppsala. In the 1740s, he was sent on several journeys through Sweden to find and classify plants and animals. In the 1750s and 1760s, he continued to collect an ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Primula Fragrans
''Primula fragrans'', synonym ''Dodecatheon redolens'', has the common name scented shooting star. It is a species of flowering plant in the primrose family. Description ''Primula fragrans'' is a hairy, thick-rooted perennial with long, clumping leaves around the base. It erects slim, tall, hairy stems which are dark in color and are topped with inflorescences of 5 to 10 showy flowers. Each flower nods with its mouth pointed to the ground when new, and becomes more erect with age. It has five reflexed sepals in shades of pink, lavender, or white which lie back against the body of the flower. Each sepal base has a blotch of bright yellow and is folded into a thick lip around the mouth of the flower. From the corolla mouth protrude large anthers which may be light pink to nearly black surrounding a threadlike stigma. Distribution This wildflower is native from California through Nevada to western Utah. It grows in moist areas, especially in the Sierra Nevada and eastern Transver ...

Primula Fassettii
''Primula'' () is a genus of herbaceous flowering plants in the family Primulaceae. They include the primrose ('' P. vulgaris''), a familiar wildflower of banks and verges. Other common species are '' P. auricula'' (auricula), '' P. veris'' (cowslip), and '' P. elatior'' (oxlip). These species and many others are valued for their ornamental flowers. They have been extensively cultivated and hybridised (in the case of the primrose, for many hundreds of years). ''Primula'' are native to the temperate Northern Hemisphere, south into tropical mountains in Ethiopia, Indonesia, and New Guinea, and in temperate southern South America. Almost half of the known species are from the Himalayas. ''Primula'' has over 500 species in traditional treatments, and more if certain related genera are included within its circumscription.''Primula''.

''Primula clevelandii'', with the common name of Padre's shooting star, is a species of Primulaceae, primrose.

Austin Mast
Austin R. Mast is a research botanist. Born in 1972, he obtained a Ph.D. from the University of Wisconsin–Madison in 2000. He is currently a professor within the Department of Biological Science at Florida State University (FSU), and has been director of FSU's Robert K. Godfrey Herbarium since August 2003. One of his main areas of research is the phylogenetics of Grevilleoideae, a subfamily of Proteaceae. In 2005 he showed the genus ''Banksia'' to be paraphyletic with respect to ''Dryandra'', Collaborating with Australian botanist Kevin Thiele, he subsequently transferred all ''Dryandra'' taxa to ''Banksia'', publishing over 120 taxonomic names in the process. The change has been adopted by the Western Australian Herbarium, although has met with some controversy. He has previously worked on the Deep South Plant Specimen Imaging Project, which created a repository of annotated high-resolution digital images of plant specimens within the East Gulf Coastal Plain The Gulf Coastal ...

Monophyly
In cladistics for a group of organisms, monophyly is the condition of being a clade—that is, a group of taxa composed only of a common ancestor (or more precisely an ancestral population) and all of its lineal descendants. Monophyletic groups are typically characterised by shared derived characteristics ( synapomorphies), which distinguish organisms in the clade from other organisms. An equivalent term is holophyly. The word "mono-phyly" means "one-tribe" in Greek. Monophyly is contrasted with paraphyly and polyphyly as shown in the second diagram. A ''paraphyletic group'' consists of all of the descendants of a common ancestor minus one or more monophyletic groups. A '' polyphyletic group'' is characterized by convergent features or habits of scientific interest (for example, night-active primates, fruit trees, aquatic insects). The features by which a polyphyletic group is differentiated from others are not inherited from a common ancestor. These definitions have taken ...

Molecular Phylogenetics
Molecular phylogenetics () is the branch of phylogeny that analyzes genetic, hereditary molecular differences, predominantly in DNA sequences, to gain information on an organism's evolutionary relationships. From these analyses, it is possible to determine the processes by which diversity among species has been achieved. The result of a molecular phylogenetic analysis is expressed in a phylogenetic tree. Molecular phylogenetics is one aspect of molecular systematics, a broader term that also includes the use of molecular data in taxonomy and biogeography. Molecular phylogenetics and molecular evolution correlate. Molecular evolution is the process of selective changes (mutations) at a molecular level (genes, proteins, etc.) throughout various branches in the tree of life (evolution). Molecular phylogenetics makes inferences of the evolutionary relationships that arise due to molecular evolution and results in the construction of a phylogenetic tree.

Petal
Petals are modified Leaf, leaves that surround the reproductive parts of flowers. They are often advertising coloration, brightly colored or unusually shaped to attract pollinators. All of the petals of a flower are collectively known as the ''corolla''. Petals are usually accompanied by another set of modified leaves called sepals, that collectively form the ''calyx'' and lie just beneath the corolla. The calyx and the corolla together make up the perianth, the non-reproductive portion of a flower. When the petals and sepals of a flower are difficult to distinguish, they are collectively called tepals. Examples of plants in which the term ''tepal'' is appropriate include Genus, genera such as ''Aloe'' and ''Tulipa''. Conversely, genera such as ''Rose, Rosa'' and ''Phaseolus'' have well-distinguished sepals and petals. When the undifferentiated tepals resemble petals, they are referred to as "petaloid", as in petaloid monocots, orders of monocots with brightly colored tepals. Sinc ...
