Polygonum Basiramia
''Polygonum basiramia'' (Synonym (taxonomy), synonym ''Polygonella basiramia'') is a rare species of flowering plant in the Polygonaceae, knotweed family known by the common names wireweed, hairy wireweed, purple wireweed, and Florida jointweed. It is endemism, endemic to Florida in the United States, where it is limited to the central ridges of the peninsula, including the Lake Wales Ridge. It is threatened by the loss and degradation of its habitat. It is a federally listed endangered species of the United States. Description This plant is a perennial herb growing 30 to 80 centimeters tall. The roots of the plant may be much longer than the plant's diameter and spread out under the soil. The wiry stems may branch and may extend beneath the surface of the soil. The plant only has leaves for a short time. They are linear in shape and measure no more than 2 or 3 centimeters in length. The stem and leaves are red to green in color. The plant is plant sexuality, gynodioecious, with s ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Tanja Schuster
Tanja Magdalena Schuster is a taxonomist from Kaindorf, Austria and the first Pauline Ladiges Plant Systematics Fellow, holding a joint position with the School of Biosciences, University of Melbourne, Victoria, Australia, and the National Herbarium of Victoria, Royal Botanic Gardens Melbourne. Schuster also worked as curator of the Norton-Brown Herbarium at the University of Maryland, College Park. In 2011, Schuster created the genus ''Duma (plant), Duma'' for some species previously placed in ''Muehlenbeckia'', but which were shown by Molecular phylogenetics, molecular phylogenetic studies to form a distinct clade. The name is derived from the Latin for "thorn-bush."

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.

Lechea Cernua
''Lechea'' (pinweed) is a genus in the family Cistaceae of the order Malvales.USDA, NRCS. 2014. The PLANTS Database (http://plants.usda.gov, 1 December 2014). National Plant Data Team, Greensboro, NC 27401-4901 USA. The genus ''Lechea'' is based primarily in eastern North America and contains about 18 species referred to as "pinweeds." Most are low-growing herbs with narrow leaves and may small flowers that resemble pinheads. Linnaeus named the genus ''Lechea'' for Swedish botanist Johan Leche (1704-1764), who taught in Finland and is regarded as the father of Finnish meteorology and space research, based on his documentation of the northern lights and early measurements of air temperature in collaboration with Anders Celsius. Species Species of ''Lechea include: *'' Lechea cernua'' *'' Lechea deckertii'' *'' Lechea divaricata'' *'' Lechea intermedia'' *''Lechea lakelae'' *''Lechea maritima'' *''Lechea mensalis'' *''Lechea minor'' *''Lechea mucronata'' *''Lechea pulchella'' *''L ...

Euphorbia Floridana
''Euphorbia'' is a very large and diverse genus of flowering plants, commonly called spurge, in the family Euphorbiaceae. "Euphorbia" is sometimes used in ordinary English to collectively refer to all members of Euphorbiaceae (in deference to the type genus), not just to members of the genus. Euphorbias range from tiny annual plants to large and long-lived trees. The genus has roughly 2,000 members, making it one of the largest genera of flowering plants. It also has one of the largest ranges of chromosome counts, along with ''Rumex'' and ''Senecio''. ''Euphorbia antiquorum'' is the type species for the genus ''Euphorbia''. It was first described by Carl Linnaeus in 1753 in ''Species Plantarum''. Some euphorbias are widely available commercially, such as poinsettias at Christmas. Some are commonly cultivated as ornamentals, or collected and highly valued for the aesthetic appearance of their unique floral structures, such as the crown of thorns plant (''Euphorbia milii''). ...

Cnidoscolus Stimulosus
''Cnidoscolus stimulosus'', the bull nettle, spurge nettle, tread-softly or finger rot, is a perennial herb covered with stinging hairs, native to southeastern North America. A member of the family Euphorbiaceae (spurge family), it is not a true nettle. It prefers sandy, well-drained soil and mostly exists in pine/blackjack oak forests on sandhills, rims of Carolina bays, dunes, dry pastures, fields and roadsides. Description The green leaves of this plant are alternate, consisting of three to five untoothed lobes. The large, white flowers have five petals. Male and female flowers are on different plants. Flowers occur throughout the spring and summer followed by a small capsule that produces three large seeds. The entire plant above ground, including the flower petals, is covered with stinging hairs. The tap root can be used as an excellent potato substitute, tasting like pasta. As the common names imply, the urticating hairs on this plant contain a caustic irritant that infli ...

Wildfire
A wildfire, forest fire, bushfire, wildland fire or rural fire is an unplanned, uncontrolled and unpredictable fire in an area of Combustibility and flammability, combustible vegetation. Depending on the type of vegetation present, a wildfire may be more specifically identified as a bushfire(bushfires in Australia, in Australia), desert fire, grass fire, hill fire, peat fire, prairie fire, vegetation fire, or veld fire. Fire ecology, Some natural forest ecosystems depend on wildfire. Wildfires are distinct from beneficial human usage of wildland fire, called controlled burn, controlled burning, although controlled burns can turn into wildfires. Fossil charcoal indicates that wildfires began soon after the appearance of terrestrial plants approximately 419 million years ago during the Silurian period. Earth's carbon-rich vegetation, seasonally dry climates, atmospheric oxygen, and widespread lightning and volcanic ignitions create favorable conditions for fires. The occurre ...
