Ravenella Sharsmithiae
''Ravenella sharsmithiae'' is a rare species of bellflower known by the common names Mt. Hamilton bellflower and Sharsmith's harebell. It is endemic to California, where it is known from just a few occurrences in the higher mountain peaks just south of the San Francisco Bay Area, including Mt. Hamilton and Mount Boardman in the Diablo Range. It is a small, hairy annual herb producing an erect stem up to 25 centimeters tall. The fleshy, toothed leaves are a centimeter long or less. The flower is funnel- or bell-shaped and purple in color. The plant is named for late local botanist Helen Sharsmith Helen Katherine Myers Sharsmith (August 26, 1905 – November 10, 1982) was an American biologist. Biography Helen Sharsmith was born 1905 in Oakland, California. She received an AB and MA from University of California, Berkeley in 1927 an ....

Plants Of The World Online
Plants of the World Online (POWO) is an online database published by the Royal Botanic Gardens, Kew. It was launched in March 2017 with the ultimate aim being "to enable users to access information on all the world's known seed-bearing plants by 2020". The initial focus was on tropical African Floras, particularly Flora Zambesiaca, Flora of West Tropical Africa and Flora of Tropical East Africa. The database uses the same taxonomical source as Kew's World Checklist of Selected Plant Families, which is the International Plant Names Index, and the World Checklist of Vascular Plants (WCVP). POWO contains 1,234,000 global plant names and 367,600 images.

Campanula
''Campanula'' () is one of several genera of flowering plants in the family Campanulaceae commonly known as bellflowers. They take both their common and scientific names from the bell-shaped flowers — ''campanula'' is Latin for "little bell". The genus includes over 500 species and several subspecies, distributed across the temperate and subtropical regions of the Northern Hemisphere, with the highest diversity in the Mediterranean region east to the Caucasus. The range also extends into mountains in tropical regions of Asia and Africa. The species include annual, biennial and perennial plants, and vary in habit from dwarf arctic and alpine species under 5 cm high, to large temperate grassland and woodland species growing to tall. Description upright=1.35, thumbThe leaves are alternate and often vary in shape on a single plant, with larger, broader leaves at the base of the stem and smaller, narrower leaves higher up; the leaf margin may be either entire or serrat ...

Endemism
Endemism is the state of a species being found in a single defined geographic location, such as an island, state, nation, country or other defined zone; organisms that are indigenous to a place are not endemic to it if they are also found elsewhere. For example, the Cape sugarbird is found exclusively in southwestern South Africa and is therefore said to be ''endemic'' to that particular part of the world. An endemic species can be also be referred to as an ''endemism'' or in scientific literature as an ''endemite''. For example '' Cytisus aeolicus'' is an endemite of the Italian flora. '' Adzharia renschi'' was once believed to be an endemite of the Caucasus, but it was later discovered to be a non-indigenous species from South America belonging to a different genus. The extreme opposite of an endemic species is one with a cosmopolitan distribution, having a global or widespread range. A rare alternative term for a species that is endemic is "precinctive", which applies to ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

San Francisco Bay Area
The San Francisco Bay Area, often referred to as simply the Bay Area, is a populous region surrounding the San Francisco, San Pablo, and Suisun Bay estuaries in Northern California. The Bay Area is defined by the Association of Bay Area Governments to include the nine counties that border the aforementioned estuaries: Alameda, Contra Costa, Marin, Napa, San Mateo, Santa Clara, Solano, Sonoma, and San Francisco. Other definitions may be either smaller or larger, and may include neighboring counties that do not border the bay such as Santa Cruz and San Benito (more often included in the Central Coast regions); or San Joaquin, Merced, and Stanislaus (more often included in the Central Valley). The core cities of the Bay Area are San Francisco, San Jose, and Oakland. Home to approximately 7.76 million people, Northern California's nine-county Bay Area contains many cities, towns, airports, and associated regional, state, and national parks, connected by a comp ...

Mount Hamilton is a mountain in the Diablo Range in Santa Clara County, California, Santa Clara County, California. The mountain's peak, at , overlooks the heavily urbanized Santa Clara Valley and is the site of Lick Observatory, the world's first permanently occupied mountain-top observatory. The asteroid 452 Hamiltonia, discovered in 1899, is named after the mountain. Golden eagle nesting sites are found on the slopes of Mount Hamilton. On clear days, Mount Tamalpais, the Santa Cruz Mountains, Monterey Bay, the Monterey Peninsula, and even Yosemite National Park are visible from the summit of the mountain. History On August 26, 1861, while working for Josiah Whitney, Josiah D. Whitney on the first California Geological Survey, William Henry Brewer, William H.

Mount Boardman is located in the Diablo Range in California. The summit is near a point where Santa Clara, Alameda, Stanislaus, and San Joaquin counties meet. It was named for W. F. Boardman, the Alameda County surveyor between 1865 and 1869. There is a higher peak to the north which is unofficially called Boardman North and has an elevation of .} This north peak, unnamed on topographic maps, is located on the Alameda – San Joaquin county line, and is the highest point in San Joaquin County.

Diablo Range
The Diablo Range is a mountain range in the California Coast Ranges subdivision of the Pacific Coast Ranges in northern California, United States. It stretches from the eastern San Francisco Bay area at its northern end to the Salinas Valley area at its southern end. Geography The Diablo Range extends from the Carquinez Strait in the north to Orchard Peak and Polonio Pass in the south, near the point where State Route 46 crosses over the Coast Ranges at Cholame, as described by the United States Geological Survey (USGS). It is bordered on the northeast by the San Joaquin River, on the southeast by the San Joaquin Valley, on the southwest by the Salinas River, and on the northwest by the Santa Clara Valley. The USGS designation is somewhat ambiguous north of the Santa Clara Valley, but on USGS maps, the range is shown as the ridgeline which runs between its namesake Mount Diablo southeastward past Mount Hamilton. Geologically, the range corresponds to the California Coast R ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
