Charles Christopher Parry
image:Charles Christopher Parry.jpg, Parry circa 1875 Charles Christopher Parry (August 28, 1823 – February 20, 1890) was a British-American botanist and Mountaineering, mountaineer. Biography Parry was born in Gloucestershire, England, but moved to the United States with his parents in 1832, settling first in Washington County, New York. He studied medicine at Columbia University, and botany under John Torrey, Asa Gray and George Engelmann. He moved to Davenport, Iowa in 1846 where he practiced as a doctor for a short time before joining the United States and Mexican Boundary Survey (1848–1855) as surgery, surgeon and botanist. He made extensive plant collections along the U.S.-Mexico border in California, and later in Colorado, Utah and other western states, many of which proved to be new species. Important plants he was the first to describe include the Torrey pine and Engelmann spruce, which he named in honour of his mentors. Dozens of plants are named after him, i ...

The Polygonaceae are a Family (biology), family of flowering plants known Common name, informally as the knotweed family or smartweed—buckwheat family in the United States. The Botanical name, name is Basionym, based on the genus ''Polygonum'', and was first used by Antoine Laurent de Jussieu in 1789 in his book, ''Genera Plantarum''.Antoine Laurent de Jussieu. 1789. ''Genera plantarum: secundum ordines naturales disposita, juxta methodum in Horto regio parisiensi exaratam''. page 82. Herrisant and Barrois: Paris, France. (see ''External links'' below) The name may refer to the many swollen Node (botany), nodes the stems of some species have, being Etymology, derived from Greek language, Greek ( meaning and meaning or ). Alternatively, it may have a different origin, meaning 'many seeds'. The Polygonaceae comprise about 1200 speciesDavid J. Mabberley. 2008. ''Mabberley's Plant-Book'' third edition (2008).

Endemism
Endemism is the state of a species being found only 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 also be referred to as an ''endemism'' or, in scientific literature, as an ''endemite''. Similarly, many species found in the Western ghats of India are examples of endemism. Endemism is an important concept in conservation biology for measuring biodiversity in a particular place and evaluating the risk of extinction for species. Endemism is also of interest in evolutionary biology, because it provides clues about how changes in the environment cause species to undergo range shifts (potentially expanding their range into a larger area or b ...

California
California () is a U.S. state, state in the Western United States that lies on the West Coast of the United States, Pacific Coast. It borders Oregon to the north, Nevada and Arizona to the east, and shares Mexico–United States border, an international border with the Mexico, Mexican state of Baja California to the south. With almost 40million residents across an area of , it is the List of states and territories of the United States by population, largest state by population and List of U.S. states and territories by area, third-largest by area. Prior to European colonization of the Americas, European colonization, California was one of the most culturally and linguistically diverse areas in pre-Columbian North America. European exploration in the 16th and 17th centuries led to the colonization by the Spanish Empire. The area became a part of Mexico in 1821, following Mexican War of Independence, its successful war for independence, but Mexican Cession, was ceded to the U ...

Endangered Species
An endangered species is a species that is very likely to become extinct in the near future, either worldwide or in a particular political jurisdiction. Endangered species may be at risk due to factors such as habitat loss, poaching, invasive species, and climate change. The International Union for Conservation of Nature (IUCN) Red List lists the global conservation status of many species, and various other agencies assess the status of species within particular areas. Many nations have laws that protect conservation-reliant species which, for example, forbid hunting, restrict land development, or create protected areas. Some endangered species are the target of extensive conservation efforts such as captive breeding and habitat restoration. Human activity is a significant cause in causing some species to become endangered. Conservation status The conservation status of a species indicates the likelihood that it will become extinct. Multiple factors are ...

Inflorescence
In botany, an inflorescence is a group or cluster of flowers arranged on a plant's Plant stem, stem that is composed of a main branch or a system of branches. An inflorescence is categorized on the basis of the arrangement of flowers on a main axis (Peduncle (botany), peduncle) and by the timing of its flowering (determinate and indeterminate). Morphology (biology), Morphologically, an inflorescence is the modified part of the Shoot (botany), shoot of spermatophyte, seed plants where flowers are formed on the axis of a plant. The modifications can involve the length and the nature of the internode (botany), internodes and the phyllotaxis, as well as variations in the proportions, compressions, swellings, adnations, connations and reduction of main and secondary axes. One can also define an inflorescence as the reproductive portion of a plant that bears a cluster of flowers in a specific pattern. General characteristics Inflorescences are described by many different charact ...

Bract
In botany, a bract is a modified or specialized leaf, associated with a reproductive structure such as a flower, inflorescence axis or cone scale. Bracts are usually different from foliage leaves in size, color, shape or texture. They also look different from the parts of the flower, such as the petals or sepals. A plant having bracts is referred to as bracteate or bracteolate, while one that lacks them is referred to as ebracteate or ebracteolate. Variants Some bracts are brightly coloured which aid in the attraction of pollinators, either together with the perianth or instead of it. Examples of this type of bract include those of '' Euphorbia pulcherrima'' (poinsettia) and '' Bougainvillea'': both of these have large colourful bracts surrounding much smaller, less colourful flowers. In grasses, each floret (flower) is enclosed in a pair of papery bracts, called the lemma (lower bract) and palea (upper bract), while each spikelet (group of florets) has a further pair o ...

Scotts Valley, California
Scotts Valley is a small city in Santa Cruz County, California, United States, about south of downtown San Jose and north of the city of Santa Cruz, in the upland slope of the Santa Cruz Mountains. As of the 2020 census, the city population was 12,224. Principal access to the city is supplied by State Route 17 that connects San Jose and Santa Cruz. The city was incorporated in 1966. History Approximately ten thousand years ago there was a lake in the lowest elevation of Scotts Valley. Archeological excavations of site CA-SCR-177 (Scotts Valley Site) in 1983 and 1987 support dates for human settlement of this area as between 9,000 and 12,000 years before present (''YBP''). The lake drained during the Mid-Holocene warming period (4,000-5,000 YBP) forming what is now known as Carbonera Creek. When the lake drained, the people moved downslope following the lake water's transformation as in became the creek. Around 2000 BC, Ohlone people occupied areas along the remaining ...

Chorizanthe
''Chorizanthe'' is a genus of plants in the buckwheat family known generally as spineflowers. These are small, squat, herbaceous plants with spiny-looking inflorescences of flowers. The flowers may be in shades of red or yellow to white. The bracts are pointed and sometimes tipped with a hooked awn, and the inflorescence often dries into a rounded, spiny husk. Spineflowers are found in western North America and South America. Name derivation: The word ''Chorizanthe'' comes from the Greek roots chorizo and anthos meaning "to divide," and "flower," thus meaning "divided flowers," but actually used in reference to the divided calyx. Selected species: * '' Chorizanthe angustifolia'' - narrowleaf spineflower * '' Chorizanthe aphanantha'' * '' Chorizanthe biloba'' - twolobe spineflower * '' Chorizanthe blakleyi'' - Blakley's spineflower * '' Chorizanthe brevicornu'' - brittle spineflower * '' Chorizanthe breweri'' - San Luis Obispo spineflower * '' Chorizanthe corrugata'' - wrinkled ...
