Stephanomeria Tenuifolia
''Stephanomeria tenuifolia'', the narrow-leaved wire-lettuce or narrow leaved stephanomeria, is a perennial plant in the family Asteraceae that grows in the Great Basin of the western United States.Great Basin Wildflowers, Laird R. Blackwell, 2006, Morris Book Publishing LLC., It has five ray flowers that give it the appearance of being petals of a single flower of a plant in another plant family. Growth pattern It grows with much branching from . Leaves and stems Leaves are threadlike. Inflorescence and fruit The inflorescence is a head with 5 square-tipped, petal-like ray flowers and sepal-like phyllaries. Fruits are seeds attached to parachute-like pappi. Habitat and range Narrow leaved stephanomeria grows in the plains and dry slopes in sagebrush steppe, mixed conifer, and mountain shrub communities in the Great Basin. In California it can be found in sagebrush scrub, Northern juniper woodland, yellow pine forest, red fir forest, lodgepole forest, and subalpine forest ...

Perennial Plant
A perennial plant or simply perennial is a plant that lives more than two years. The term ('' per-'' + '' -ennial'', "through the years") is often used to differentiate a plant from shorter-lived annuals and biennials. The term is also widely used to distinguish plants with little or no woody growth (secondary growth in girth) from trees and shrubs, which are also technically perennials. Perennialsespecially small flowering plantsthat grow and bloom over the spring and summer, die back every autumn and winter, and then return in the spring from their rootstock or other overwintering structure, are known as herbaceous perennials. However, depending on the rigours of local climate (temperature, moisture, organic content in the soil, microorganisms), a plant that is a perennial in its native habitat, or in a milder garden, may be treated by a gardener as an annual and planted out every year, from seed, from cuttings, or from divisions. Tomato vines, for example, live several y ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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 ...

Great Basin
The Great Basin is the largest area of contiguous endorheic basin, endorheic watersheds, those with no outlets, in North America. It spans nearly all of Nevada, much of Utah, and portions of California, Idaho, Oregon, Wyoming, and Baja California. It is noted for both its arid climate and the basin and range topography that varies from the North American low point at Badwater Basin in Death Valley to the highest point of the contiguous United States, less than away at the summit of Mount Whitney. The region spans several physical geography, physiographic divisions, biomes, ecoregions, and deserts. Definition The term "Great Basin" is applied to hydrography, hydrographic, ecology, biological, floristic province, floristic, physiographic, topography, topographic, and Ethnography, ethnographic geographic areas. The name was originally coined by John C. Frémont, who, based on information gleaned from Joseph R. Walker as well as his own travels, recognized the hydrographic nature o ...

Phyllary
In botanical terminology, a phyllary, also known an involucral bract or tegule, is a single bract of the involucre of a composite flower. The involucre is the grouping of bracts together. Phyllaries are reduced leaf-like structures that form one or more whorls immediately below a flower head. Function Phyllaries provide protection to developing flowers and fruits. In the dandelion hybrid ''Taraxacum japonicum'' × ''officinale'', recurved phyllaries help defend the flowers from herbivory by slugs. They sometimes assist in the dispersal of fruits. The hooked phyllaries of burdock species (''Arctium'') cling to the fur and feathers of animals, dispersing the seeds away from the parent plant (exozoochory). Structure and arrangement Phyllary morphology is useful in plant identification as between species of the 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.

Pappus (botany)
In Asteraceae, the pappus is the modified calyx, the part of an individual floret, that surrounds the base of the corolla tube in flower. It functions as a wind-dispersal mechanism for the seeds. The term is sometimes used for similar structures in other plant families e.g. in certain genera of the Apocynaceae, although the pappus in Apocynaceae is not derived from the calyx of the flower. In Asteraceae, the pappus may be composed of bristles (sometimes feathery), awns, scales, or may be absent, and in some species, is too small to see without magnification. In genera such as ''Taraxacum'' or ''Eupatorium'', feathery bristles of the pappus function as a "parachute" which enables the seed to be carried by the wind. The name derives from the Ancient Greek word ''pappos'', Latin ''pappus'', meaning "old man", so used for a plant (assumed to be an ''Erigeron'' species) having bristles and also for the woolly, hairy seed of certain plants. The pappus of the dandelion plays a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Mountain Shrub
A mountain is an elevated portion of the Earth's crust, generally with steep sides that show significant exposed bedrock. Although definitions vary, a mountain may differ from a plateau in having a limited summit area, and is usually higher than a hill, typically rising at least 300 metres (1,000 feet) above the surrounding land. A few mountains are isolated summits, but most occur in mountain ranges. Mountains are formed through tectonic forces, erosion, or volcanism, which act on time scales of up to tens of millions of years. Once mountain building ceases, mountains are slowly leveled through the action of weathering, through slumping and other forms of mass wasting, as well as through erosion by rivers and glaciers. High elevations on mountains produce colder climates than at sea level at similar latitude. These colder climates strongly affect the ecosystems of mountains: different elevations have different plants and animals. Because of the less hospitable terrain and ...

Sagebrush Scrub
Sagebrush scrub is a vegetation type (biome) of mid to high elevation Western United States deserts characterized by low growing, drought resistant shrubs including sagebrush (''Artemisia tridentata'') and its associates.Karen Wiese, Sierra Nevada Wildflowers, 2013, p. 18-19Pam Mackay, Mojave Desert Wildflowers, p19 It is the dominant vegetation type of the Great Basin Desert (Great Basin shrub steppe), occurs along the margins of the Mojave Desert, including in the southern slopes of the Sierra Nevadas and Transverse Ranges of California, and occurs in the Colorado Plateau and Canyonlands region, where it may be referred to as cool desert shrub.Damian Fagan, Canyon Country Wildflowers, p3 It often occurs adjacent to Pinyon-juniper woodland communities, between 4,000 and 7,000 feet elevation, and where annual precipitation is 8"-15", much falling as snow. Sometimes it occurs in pure stands of sagebrush, or with associates that vary from region to region. Sagebrush scrub may occur ...

Juniper Woodland
Junipers are coniferous trees and shrubs in the genus ''Juniperus'' () of the cypress family Cupressaceae. Depending on the taxonomy, between 50 and 67 species of junipers are widely distributed throughout the Northern Hemisphere, from the Arctic, south to tropical Africa, throughout parts of western, central and southern Asia, east to eastern Tibet in the Old World, and in the mountains of Central America. The highest-known juniper forest occurs at an altitude of in southeastern Tibet and the northern Himalayas, creating one of the highest tree lines on earth. Description Junipers vary in size and shape from tall trees, tall, to columnar or low-spreading shrubs with long, trailing branches. They are evergreen with needle-like and/or scale-like leaves. They can be either monoecious or dioecious. The female seed cones are very distinctive, with fleshy, fruit-like coalescing scales which fuse together to form a berrylike structure ( galbulus), long, with one to 12 unwi ...

Yellow Pine Forest
Ponderosa pine forest is a plant association and plant community dominated by ponderosa pine and found in western North America. It is found from the Rocky Mountains to the Pacific Coast Ranges in the Western United States and Western Canada. In the south and east, ponderosa pine forest is the climax forest, while in the more northern part of its range, it can transition to Douglas-fir or grand fir, or white fir forests. Understory species depends on location. Fire suppression has led to insect outbreaks in ponderosa pine forests. Physiography Since ponderosa pine has a rather wide range of adaptability and can dominate some of the less mesic true forest sites, it occupies low mountains and foothills in many places; yet in mixtures with other species, it is found at moderate elevations. Ponderosa pine forest is the largest western forest type in the United States. Ponderosa pine is the principal species on over and is present on an additional . Within the western United States ...
