Cupressus Goveniana
''Hesperocyparis goveniana'' commonly known as Californian cypress and Gowen cypress, is a species of western cypress that is endemic to a small area of coastal California near Monterey. It was formerly classified as ''Cupressus goveniana''. Distribution The tree is endemic to the Monterey Peninsula in coastal Monterey County, located on the Central Coast of California, in the Western United States. The tree is found in small, scattered populations, and not in large forests of its species. ''Hesperocyparis goveniana'' occurs with ''Hesperocyparis macrocarpa'' (Monterey cypress), in the two groves where the Monterey cypress occurs naturally, in Monterey County. Outside of California, ''Hesperocyparis goveniana'' has been introduced to Robinson Crusoe Island in Chile. It is on the IUCN Red List of endangered species. Description ''Hesperocyparis goveniana'' is an evergreen tree with a conic to ovoid-conic crown, very variable in size, with mature trees of under on some sites, t ...

UC Botanical Garden
The University of California Botanical Garden is a 34-acre (13.7 ha) botanical garden located on the University of California, Berkeley campus, in Strawberry Canyon. The garden is in the Berkeley Hills, inside the city boundary of Oakland, with views overlooking the San Francisco Bay. It is one of the most diverse plant collections in the United States, and famous for its large number of rare and endangered species. History Development The garden is situated on the land of the Chochenyo speaking Ohlone people called xučyun (Huichin). In the 1870s, a few years after the founding of the University of California, Berkeley, Dr. Eugene W. Hilgard, the university's first Dean of Agriculture, established a garden of plants on the land which is now Moffit Library. The University of California Botanical Garden was initially established in 1890 near Haviland Hall on the north side of campus by E.L. Greene, the first chairman of the Department of Botany, to preserve the trees, shr ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Foliage
A leaf (: leaves) is a principal appendage of the stem of a vascular plant, usually borne laterally above ground and specialized for photosynthesis. Leaves are collectively called foliage, as in "autumn foliage", while the leaves, stem, flower, and fruit collectively form the shoot system. In most leaves, the primary photosynthetic tissue is the palisade mesophyll and is located on the upper side of the blade or lamina of the leaf, but in some species, including the mature foliage of ''Eucalyptus'', palisade mesophyll is present on both sides and the leaves are said to be isobilateral. The leaf is an integral part of the stem system, and most leaves are flattened and have distinct upper ( adaxial) and lower ( abaxial) surfaces that differ in color, hairiness, the number of stomata (pores that intake and output gases), the amount and structure of epicuticular wax, and other features. Leaves are mostly green in color due to the presence of a compound called chlorophyll ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Natural Resources Conservation Service
Natural Resources Conservation Service (NRCS), formerly known as the Soil Conservation Service (SCS), is an agency of the United States Department of Agriculture (USDA) that provides technical assistance to farmers and other private landowners and managers. Its name was changed in 1994 during the presidency of Bill Clinton to reflect its broader mission. It is a relatively small agency, currently comprising about 12,000 employees. Its mission is to improve, protect, and conserve natural resources on private lands through a cooperative partnership with State governments of the United States, state and Local government in the United States, local agencies. While its primary focus has been agriculture, agricultural lands, it has made many technical contributions to soil surveying, soil classification, classification, and water quality improvement. One example is the Conservation Effects Assessment Project (CEAP), set up to quantify the benefits of agricultural conservation efforts pr ...

World Flora Online
World Flora Online is an Internet-based compendium of the world's plant species. Description The World Flora Online (WFO) is an open-access database, launched in October 2012 as a follow-up project to The Plant List, with the aim of publishing an online flora of all known plants by 2020. It is a project of the United Nations Convention on Biological Diversity, with goal of halting the loss of plant species worldwide by 2020. It is developed by a collaborative group of institutions around the world in response to the 2011–2020 Global Strategy for Plant Conservation (GSPC)'s updated Target 1: to produce "an online flora of all known plants". An accessible flora of all known plant species was considered a fundamental requirement for plant conservation. It provides a baseline for the achievement and monitoring of other targets of the strategy. The previous target of GSPC was achieved in 2010 with The Plant List. WFO was conceived in 2012 by an initial group of four instituti ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Plants Of The World Online
Plants of the World Online (POWO) is an online taxonomic database published by the Royal Botanic Gardens, Kew. History Following the Convention on Biological Diversity, the Royal Botanic Gardens in Kew launched Plants of the World Online in March 2017 with the goal of creating an exhaustive online database of all seed-bearing plants worldwide. (Govaerts wrongly speaks of "Convention for Botanical Diversity (CBD)). The initial focus was on tropical African flora, particularly flora ''Zambesiaca'', flora of West and East Tropical Africa. Since March 2024, the website has displayed AI-generated predictions of the extinction risk for each plant. Description The database uses the same taxonomical source as the International Plant Names Index, which is the World Checklist of Vascular Plants (WCVP).

Hesperocyparis
''Hesperocyparis'' (western cypress) is a genus of trees in the family Cupressaceae, containing North American species otherwise assigned to the genus ''Cupressus''. They are found throughout western North America. Only a few species have wide ranges, with most being restricted-range endemics. Taxonomy Members of ''Hesperocyparis'' were and still are placed in ''Cupressus'' by many authorities, but phylogenetic evidence supports a different affinity. A 2021 molecular study found ''Hesperocyparis'' to be the sister group to the genus '' Callitropsis'' (containing only the Nootka cypress), with this clade being sister to the Asian genus ''Xanthocyparis'', containing only the Vietnamese golden cypress. The clade comprising all three genera was found to be sister to a clade containing ''Juniperus'' and ''Cupressus sensu stricto''. If ''Hesperocyparis'' and the other smaller genera were reunited with ''Cupressus'' it may also require them to be merged into a larger genus including ...

Juniperus
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 as far south as tropical Africa, including the Arctic, parts of Asia, and 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 unwinged, hard-shelled seeds. In some species, these "berries" are red-brown or orange, but ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Cupressus
''Cupressus'' (common name cypress) is one of several genus, genera of evergreen conifers within the Family (biology), family Cupressaceae; for the others, see cypress. It is considered a Polyphyly, polyphyletic group. Based on genetic and morphological analysis, the genus ''Cupressus'' is found in the subfamily Cupressoideae. The common name "cypress" comes via the Old French from the Latin , which is the Latinisation (literature), latinisation of the Greek language, Greek κυπάρισσος (''kypárissos''). The name derives from Cyparissus, a mythological figure who was turned into a tree after killing a stag. As currently treated, these cypresses are native plants in scattered localities in mainly warm temperate climate regions in the Northern Hemisphere, including northwest Africa, the Middle East, the Himalayas, southern China and northern Vietnam. As with other pinophyta, conifers, extensive cultivation has led to a wide variety of forms, sizes and colours, that are gro ...

James Robert Gowen
James Robert Gowen (1784–1862) was an amateur English botanist and horticulturist, who was secretary of the Royal Horticultural Society (RHS) from 1845 to 1850, treasurer until 1855, a landowner in the Wairau Valley in 1848, was still paying rates in Nelson in 1862 and was a director of the New Zealand Company from 1840 to 1854. He was a lay member of the Lunacy Commission from 1842 to 1844 and patron of the Nelson Agricultural and Horticultural Society in 1845. The RHS lists 12 rhododendron varieties created by Gowen between 1826 and 1842 at Highclere Castle, on the Berkshire-Hampshire border, the home of the second Earl of Carnarvon, who was RHS Vice-President from 1829 to 1833. James Carton was head gardener at Highclere. At the request of Gowen, Carton's Rhododendron, a variety bred in 1825 was named after the gardener, by Professor John Lindley. In 1831 Lindley also named Govenia orchids after Gowen. Gowen Cypress, a Monterey conifer, was named after him by the RHS forem ...

Karl Theodor Hartweg
Karl Theodor Hartweg (18 June 1812 – 3 February 1871) was a German botanist. He collected numerous new species of plants in Colombia, Ecuador, Guatemala, Mexico and California in the United States, collecting for the London Horticultural Society. Many of the species he discovered were formally published, with attribution, by George Gordon, the Foreman of the London Horticultural Society Gardens and a specialist in the conifers which were well represented in Hartweg's collections. Many plants collected in Mexico by Hartweg from 1836 onward were identified and catalogued by George Bentham George Bentham (22 September 1800 – 10 September 1884) was an English botanist, described by the weed botanist Duane Isely as "the premier systematic botanist of the nineteenth century".

Seed
In botany, a seed is a plant structure containing an embryo and stored nutrients in a protective coat called a ''testa''. More generally, the term "seed" means anything that can be Sowing, sown, which may include seed and husk or tuber. Seeds are the product of the ripened ovule, after the embryo sac is fertilization, fertilized by Pollen, sperm from pollen, forming a zygote. The embryo within a seed develops from the zygote and grows within the mother plant to a certain size before growth is halted. The formation of the seed is the defining part of the process of reproduction in seed plants (spermatophytes). Other plants such as ferns, mosses and marchantiophyta, liverworts, do not have seeds and use water-dependent means to propagate themselves. Seed plants now dominate biological Ecological niche, niches on land, from forests to grasslands both in hot and cold climates. In the flowering plants, the ovary ripens into a fruit which contains the seed and serves to disseminate ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
