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] |
Markagunt Plateau
Markagunt Plateau is a volcanic field in southern Utah, United States. Formed in a region of older volcanics, it consists of several cinder cones and associated lava flows. Some of the lava flows feature lava tubes such as Mammoth Cave, while others have formed lava dams and lakes like Navajo Lake. Volcanism took place during the Pliocene and latest Pleistocene but may have continued into the Holocene; legends of the Southern Paiute may reflect past eruptions. Geography and geomorphology The Markagunt Plateau is in southern Utah in the counties Iron County, Garfield County and Kane County. Cedar City lies west and Kanab south of the volcanic field, which is crossed by Utah State Route 14, Utah State Route 143 and Utah State Route 148. Towns in the area include Duck Creek Village and Mammoth Creek. The volcanic field is on a plateau bordered to the south by the Pink Cliffs and to the west by the cliffs of Cedar Breaks National Monument, and features lava flows and over 25 cin ...

Packera
''Packera'' is a genus of about 64 species of plants in the daisy family, Asteraceae. Most species are commonly called ragworts or grounsels. Its members were previously included in the genus ''Senecio'' (where they were called ''aureoid senecios'' by Asa Gray), but were divided out based on chromosome numbers, a variety of morphological characters, and molecular phylogeny.

Weed
A weed is a plant considered undesirable in a particular situation, "a plant in the wrong place", or a plant growing where it is not wanted.Harlan, J. R., & deWet, J. M. (1965). Some thoughts about weeds. ''Economic botany'', ''19''(1), 16-24. This introduces the concept of humans and their goals in a particular setting.Holzner, W., & Numata, M. (Eds.). (2013). ''Biology and ecology of weeds'' (Vol. 2). Springer Science & Business Media. The concept of weeds is particularly significant in agriculture, where the aim is growing crops or pastures of a single species, or a mixture of a few desired species. In such environments, other plant species are considered undesirable and therefore a weed. Besides, some weeds have undesirable characteristics making them a plant pest in most human settings.Harlan, J. R., & deWet, J. M. (1965). Some thoughts about weeds.

Cedar Breaks National Monument
Cedar Breaks National Monument is a U.S. National Monument located in the U.S. state of Utah near Cedar City. Cedar Breaks is a natural amphitheater, stretching across , with a depth of over . The elevation of the rim of the amphitheater is over above sea level. Rising above the rim is the prominent Brian Head, the peak of which lies a short distance outside of the National Monument boundary. The rock of the amphitheater is more eroded than, but otherwise similar to, formations at nearby Bryce Canyon National Park, Red Canyon in Dixie National Forest, and select areas of Cedar Mountain (SR-14). Because of its elevation, snow often makes parts of the park inaccessible to vehicles from October through May. Its rim visitor center is open from June through October. Several hundred thousand people visit the monument annually. The monument area is the headwaters of Mammoth Creek, a tributary of the Sevier River.

Dixie National Forest
Dixie National Forest is a United States National Forest in Utah with headquarters in Cedar City. It occupies almost two million acres (8,000 km²) and stretches for about across southern Utah. The largest national forest in Utah, it straddles the divide between the Great Basin and the Colorado River. In descending order of forestland area it is located in parts of Garfield, Washington, Iron, Kane, Wayne, and Piute counties. The majority (over 55%) of forest acreage lies in Garfield County. Elevations vary from above sea level near St. George, Utah to at Blue Bell Knoll on Boulder Mountain. The southern rim of the Great Basin, near the Colorado River, provides spectacular scenery. Colorado River canyons are made up of multi-colored cliffs and steep-walled gorges. The Forest is divided into four geographic areas. High altitude forests in gently rolling hills characterize the Markagunt, Paunsaugunt, and Aquarius Plateaus. Boulder Mountain, one of the largest high-e ...

Claron Formation
The exposed geology of the Bryce Canyon area in Utah shows a record of deposition that covers the last part of the Cretaceous Period and the first half of the Cenozoic era in that part of North America. The ancient depositional environment of the region around what is now Bryce Canyon National Park varied from the warm shallow sea (called the Cretaceous Seaway) in which the Dakota Sandstone and the Tropic Shale were deposited to the cool streams and lakes that contributed sediment to the colorful Claron Formation that dominates the park's amphitheaters. Other formations were also formed but were mostly eroded following uplift from the Laramide orogeny which started around 70 million years ago ( mya). This event raised the Rocky Mountains far to the east and caused the retreat of the sea that covered the Bryce Canyon area. After Laramide mountain building came to an end, about 15 mya, a large part of western North America began to be stretched into the nearby Basin and ...

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 ...
