Coast Silk-tassel
''Garrya elliptica'', the coast silk-tassel, silk tassel bush or wavyleaf silktassel, is a species of flowering plant in the family (biology), family Garryaceae, native plant, native to the coastal ranges of California and southern Oregon. It is an erect, bushy, evergreen shrub reaching a height of . Description Growth habit It has a multi-furcate branching structure yielding an almost spherical form. The height averages in the wild. Like others of its genus, ''G. elliptica'' has opposite leaves with a tough leathery feel, glossy green on top, but paler and duller on the underside. Flowers The dioecious flowers are concentrated in inflorescences which cascade downward as ament (botany), aments of in length. While it manifests separate male and female plants, the pendant male catkins are much more showy and are grey-green and up to long; the female ones are shorter and silver-grey. Although the flowers bloom in late winter and early spring, dried bracts remain on the plant ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Pistil
Gynoecium (; ; : gynoecia) is most commonly used as a collective term for the parts of a flower that produce ovules and ultimately develop into the fruit and seeds. The gynoecium is the innermost whorl (botany), whorl of a flower; it consists of (one or more) ''#Pistil, pistils'' and is typically surrounded by the pollen-producing plant reproductive morphology, reproductive organs, the stamens, collectively called the androecium. The gynoecium is often referred to as the "female" portion of the flower, although rather than directly producing female gametes (i.e. egg cells), the gynoecium produces megaspores, each of which develops into a female gametophyte which then produces egg cells. The term gynoecium is also used by botanists to refer to a cluster of archegonia and any associated modified leaves or stems present on a gametophyte shoot in mosses, Marchantiophyta, liverworts, and hornworts. The corresponding terms for the male parts of those plants are clusters of antheridiu ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Clay
Clay is a type of fine-grained natural soil material containing clay minerals (hydrous aluminium phyllosilicates, e.g. kaolinite, ). Most pure clay minerals are white or light-coloured, but natural clays show a variety of colours from impurities, such as a reddish or brownish colour from small amounts of iron oxide. Clays develop plasticity (physics), plasticity when wet but can be hardened through Pottery#Firing, firing. Clay is the longest-known ceramic material. Prehistoric humans discovered the useful properties of clay and used it for making pottery. Some of the earliest pottery shards have been radiocarbon dating, dated to around 14,000 BCE, and Clay tablet, clay tablets were the first known writing medium. Clay is used in many modern industrial processes, such as paper making, cement production, and chemical filtration, filtering. Between one-half and two-thirds of the world's population live or work in buildings made with clay, often baked into brick, as an essenti ...

Coastal Sage Scrub
Coastal sage scrub, also known as coastal scrub, CSS, or soft chaparral, is a low scrubland plant community of the California coastal sage and chaparral subecoregion, found in coastal California and northwestern coastal Baja California. It is within the California chaparral and woodlands ecoregion, of the Mediterranean forests, woodlands, and scrub biome. Characteristics ;Plant community Coastal sage scrub is characterized by low-growing aromatic, and drought-deciduous shrubs adapted to the semi-arid Mediterranean climate of the coastal lowlands. The community is sometimes called "soft chaparral" due to the predominance of soft, drought-deciduous leaves in contrast to the hard, waxy-cuticled leaves on sclerophyllous plants of California's chaparral communities. ;Flora Characteristic shrubs and subshrubs include: * California sagebrush (''Artemisia californica'') * Black sage (''Salvia mellifera'') * White sage (''Salvia apiana'') * California buckwheat (''Eriogonum fasci ...

California Mixed Evergreen Forest
: California mixed evergreen forest is a plant community found in the mountain ranges of California and southwestern Oregon. The Mixed evergreen forest plant community is native to the Northern and Southern California Coast Ranges and Sierra Nevada of central and northern California; the Transverse Ranges and Peninsular Ranges of southern California; and the southwestern Oregon Coast Ranges. California mixed evergreen forests occur in ecoregions of the California Floristic Province, including in areas of the California chaparral and woodlands and its sub-ecoregions, Klamath Mountains (ecoregion), Klamath-Siskiyou Mountains forests, Northern California coastal forests, and Sierra Nevada lower montane forest. The mixed evergreen forests of each ecoregion have slightly different species composition. Klamath-Siskiyou mixed evergreen forest The mixed evergreen forests of the Klamath Mountains-Siskiyou Mountains occur above 300 meters (1000 ft) elevation, and are of four main ty ...

Northern Coastal Scrub
Northern coastal scrub is a diverse scrubland plant community found along the Pacific Coast from Northern California to Southern Oregon, as well as some offshore islands. It frequently forms a landscape mosaic with California coastal prairie, coastal prairie. Description Northern coastal scrub is found on various rocky coastal land forms along the Pacific Coast. It is observed as either patchy ocean-side cover near coastal prairie or a dense and continuous shrub cover over perennial herbaceous plants. Northern coastal scrub will form a landscape mosaic with coastal prairie on sites with thicker, more moist soil. The conditions are harsh, with high exposure to wind and salt deposition and generally low-quality soil. The vegetation of coastal scrub communities is mostly composed of resilient short shrubs with flexible branches growing from a rigid, woody base. Climate Northern coastal scrub and coastal prairie generally occur where the Pacific Ocean moderates summer drought. A ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
California Coastal Sage And Chaparral Ecoregion
The California coastal sage and chaparral () is a Mediterranean forests, woodlands, and scrub ecoregion, defined by the World Wildlife Fund, located in southwestern California (United States) and northwestern Baja California (Mexico).

Pacific Ocean
The Pacific Ocean is the largest and deepest of Earth's five Borders of the oceans, oceanic divisions. It extends from the Arctic Ocean in the north to the Southern Ocean, or, depending on the definition, to Antarctica in the south, and is bounded by the continents of Asia and Australia in the west and the Americas in the east.

Garrya Fremontii
''Garrya fremontii'' is a species of flowering shrub known by several common names, including California fever bush, bearbrush, and Frémont's silktassel. Both the latter name, and the plant's specific epithet are derived from John C. Frémont. Distribution The plant is native to the West coast of the United States, from Washington to California. It can be found in a number of habitats, from mountain forest to woodlands and chaparral canyons and slopes.

Garrya Congdonii
''Garrya congdonii'', the chaparral silktassel or Congdon silktassel, a fairly common evergreen shrub native to the northern California Coast Ranges, is one of a small biological family of approximately twenty known species in the family Garryaceae, most of which are ''Garrya''. While the female and male sexual organs of Congdon silktassel are on separate plants, the pendant male catkins are much more showy. This plant is reasonably attractive and neat enough in its growing habit to be appealing as a landscape species. It is stocked commonly at commercial plant nurseries. All ''Garrya'' are associated with warm temperate regions of North America. Description 240px, Leaves and spent blooms Congdon silktassel has a multi-furcate trunk branching structure yielding an almost spherical form. The height can attain four meters, but more commonly averages two to three meters in the wild. Congdon silktassel, as all the genus ''Garrya'', have opposite leaves that have a tough leathery f ...
