Charles Christopher Parry
Parry circa 1875 Charles Christopher Parry (August 28, 1823 – February 20, 1890) was a British-American botanist and 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 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, including the Parry Pinyon, Parry's Lily, Parry's primros ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Polygonaceae
The Polygonaceae are a family of flowering plants known informally as the knotweed family or smartweed—buckwheat family in the United States. The name is 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 nodes the stems of some species have, being derived from Greek, ''poly'' meaning 'many' and ''gony'' meaning 'knee' or 'joint'. Alternatively, it may have a different derivation, meaning 'many seeds'. The Polygonaceae comprise about 1200 speciesDavid J. Mabberley. 2008. ''Mabberley's Plant-Book'' third edition (2008). Cambridge University Press: UK. distributed into about 48 genera. The largest genera are ''Eriogonum'' (240 species), ''Rumex'' (20 ...

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] |

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 and invasive species. 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 considered when assessing the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Inflorescence
An inflorescence is a group or cluster of flowers arranged on a stem that is composed of a main branch or a complicated arrangement of branches. Morphologically, it is the modified part of the shoot of seed plants where flowers are formed on the axis of a plant. The modifications can involve the length and the nature of the 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. The stem holding the whole inflorescence is called a peduncle. The major axis (incorrectly referred to as the main stem) above the peduncle bearing the flowers or secondary branches is called the rachis. The stalk of each flower in the inflorescence is called a pedicel. A flower that is not part of an inflorescence is called a solitary flower and its stalk is al ...

Bract
In botany, a bract is a modified or specialized leaf, especially one associated with a reproductive structure such as a flower, inflorescence axis or cone scale. Bracts are usually different from foliage leaves. They may be smaller, larger, or of a different color, shape, or texture. Typically, 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 and ebracteolate, without bracts. Variants Some bracts are brightly-coloured and serve the function of attracting 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 p ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Scotts Valley, California
Scotts Valley is a small city in Santa Cruz County, California, United States, about thirty miles (48 km) south of downtown San Jose and six miles (10 km) 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, and Paleo Indians lived near its shores. Archeological excavations of site CA-SCR-177 in 1983 and 1987 support dates for human settlement of this area as between 9,000 to 12,000 years before present (''YBP''). The lake later receded to form a peat bog. Later, around 2000 BC, Ohlone people occupied areas along the remaining creeks, spring and seep areas, along with permanent and seasonal drainages, and on flat ridges and terraces. Therefore, ar ...

Chorizanthe
''Chorizanthe'' is a genus of plants in the Polygonaceae, 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 (botany), 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.
