Hesperocyparis Macrocarpa
''Hesperocyparis macrocarpa'' is a coniferous tree. It is commonly known as the Monterey cypress and is one of several species of cypress trees endemic to California. The Monterey cypress is found naturally only on the Central Coast of California. The natural distributional range of the species during modern times is confined to two small relict populations near Carmel, California, at Cypress Point in Pebble Beach and at Point Lobos. Historically during the peak of the last ice age, Monterey cypress would have likely comprised a much larger forest that extended much further north and south.Axelrod, D. I. (1982)AGE AND ORIGIN OF THE MONTEREY ENDEMIC AREA.''Madroño'', ''29''(3), 127–147. Description ''Hesperocyparis macrocarpa'' is a medium-sized coniferous evergreen tree, which often becomes irregular and flat-topped as a result of the strong winds that are typical of its native area. It grows to heights of up to 40 meters (133 feet) in perfect growing conditions, a ...

Lone Cypress
The Lone Cypress is a Monterey cypress tree located in Pebble Beach, California. Standing atop a granite headland overlooking Carmel Bay, the tree has become a Western icon and has been called one of the most photographed trees in North America. History Early history The tree is believed to have been seeded circa 1750 in what was then the Spanish colony of New Spain. However, due to the invasive nature of traditional dendrochronology, the precise age of the tree is unknown and can only be inferred. Over the centuries the tree has been weathered by the wind and salt spray coming off the Pacific Ocean, gradually altering its appearance. The earliest known depictions of the tree's likeness in paintings and photographs date to the 1880s, which shows the tree with a lush dome-shaped canopy. 20th century In 1941, a stone retaining wall was constructed around the base of the tree to protect its roots from erosion. In 1948, a series of cables were installed to help support the tree. ...

Binomial Nomenclature
In taxonomy, binomial nomenclature ("two-term naming system"), also called nomenclature ("two-name naming system") or binary nomenclature, is a formal system of naming species of living things by giving each a name composed of two parts, both of which use Latin grammatical forms, although they can be based on words from other languages. Such a name is called a binomial name (which may be shortened to just "binomial"), a binomen, name or a scientific name; more informally it is also historically called a Latin name. The first part of the name – the '' generic name'' – identifies the genus to which the species belongs, whereas the second part – the specific name or specific epithet – distinguishes the species within the genus. For example, modern humans belong to the genus ''Homo'' and within this genus to the species ''Homo sapiens''. ''Tyrannosaurus rex'' is likely the most widely known binomial. The ''formal'' introduction of this system of naming species is credit ...

Glaucous
''Glaucous'' (, ) is used to describe the pale grey or bluish-green appearance of the surfaces of some plants, as well as in the names of birds, such as the glaucous gull (''Larus hyperboreus''), glaucous-winged gull (''Larus glaucescens''), glaucous macaw (''Anodorhynchus glaucus''), and glaucous tanager (''Thraupis glaucocolpa''). The term ''glaucous'' is also used botanically as an adjective to mean "covered with a greyish, bluish, or whitish waxy coating or bloom that is easily rubbed off" (e.g. glaucous leaves). The first recorded use of ''glaucous'' as a color name in English was in the year 1671. Examples The epicuticular wax coating on mature plum fruit gives them a glaucous appearance. Another familiar example is found in the common grape genus (''Vitis vinifera''). Some cacti have a glaucous coating on their stem(s). Glaucous coatings are hydrophobic so as to prevent wetting by rain. Their waxy character serves to hinder climbing of leaves, stem or fruit by insec ...

Cotyledon
A cotyledon (; ; ; , gen. (), ) is a significant part of the embryo within the seed of a plant, and is defined as "the embryonic leaf in seed-bearing plants, one or more of which are the first to appear from a germinating seed." The number of cotyledons present is one characteristic used by botanists to classify the flowering plants (angiosperms). Species with one cotyledon are called monocotyledonous ("monocots"). Plants with two embryonic leaves are termed dicotyledonous ("dicots"). In the case of dicot seedlings whose cotyledons are photosynthetic, the cotyledons are functionally similar to leaves. However, true leaves and cotyledons are developmentally distinct. Cotyledons are formed during embryogenesis, along with the root and shoot meristems, and are therefore present in the seed prior to germination. True leaves, however, are formed post-embryonically (i.e. after germination) from the shoot apical meristem, which is responsible for generating subsequent aerial por ...

Morphology (biology)
Morphology is a branch of biology dealing with the study of the form and structure of organisms and their specific structural features. This includes aspects of the outward appearance (shape, structure, colour, pattern, size), i.e. external morphology (or eidonomy), as well as the form and structure of the internal parts like bones and organs, i.e. internal morphology (or anatomy). This is in contrast to physiology, which deals primarily with function. Morphology is a branch of life science dealing with the study of gross structure of an organism or taxon and its component parts. History The etymology of the word "morphology" is from the Ancient Greek (), meaning "form", and (), meaning "word, study, research". While the concept of form in biology, opposed to function, dates back to Aristotle (see Aristotle's biology), the field of morphology was developed by Johann Wolfgang von Goethe (1790) and independently by the German anatomist and physiologist Karl Friedrich Burdach ...

Hybrid (biology)
In biology, a hybrid is the offspring resulting from combining the qualities of two organisms of different breeds, varieties, species or genera through sexual reproduction. Hybrids are not always intermediates between their parents (such as in blending inheritance), but can show hybrid vigor, sometimes growing larger or taller than either parent. The concept of a hybrid is interpreted differently in animal and plant breeding, where there is interest in the individual parentage. In genetics, attention is focused on the numbers of chromosomes. In taxonomy, a key question is how closely related the parent species are. Species are reproductively isolated by strong barriers to hybridisation, which include genetic and morphological differences, differing times of fertility, mating behaviors and cues, and physiological rejection of sperm cells or the developing embryo. Some act before fertilization and others after it. Similar barriers exist in plants, with differences in flowering tim ...

Common Descent
Common descent is a concept in evolutionary biology applicable when one species is the ancestor of two or more species later in time. All living beings are in fact descendants of a unique ancestor commonly referred to as the last universal common ancestor (LUCA) of all life on Earth, according to modern evolutionary biology. Common descent is an effect of speciation, in which multiple species derive from a single ancestral population. The more recent the ancestral population two species have in common, the more closely are they related. The most recent common ancestor of all currently living organisms is the last universal ancestor, which lived about 3.9 billion years ago. The two earliest pieces of evidence for life on Earth are graphite found to be biogenic in 3.7 billion-year-old metasedimentary rocks discovered in western Greenland and microbial mat fossils found in 3.48 billion-year-old sandstone discovered in Western Australia. All currently living organisms on Earth sha ...

Juniper
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, from the Arctic, south to tropical Africa, throughout parts of West Asia, western, Central Asia, central and South Asia, southern Asia, east to eastern Tibet in the Old World, and in the mountains of 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 Conifer cone, seed cones are very distinctive, with fleshy, fruit-like coalescing scales which fuse together to form Juniper berry, a&n ...

Systematic Botany
Plant taxonomy is the science that finds, identifies, describes, classifies, and names plants. It is one of the main branches of taxonomy (the science that finds, describes, classifies, and names living things). Plant taxonomy is closely allied to plant systematics, and there is no sharp boundary between the two. In practice, "plant systematics" involves relationships between plants and their evolution, especially at the higher levels, whereas "plant taxonomy" deals with the actual handling of plant specimens. The precise relationship between taxonomy and systematics, however, has changed along with the goals and methods employed. Plant taxonomy is well known for being turbulent, and traditionally not having any close agreement on circumscription and placement of taxa. See the list of systems of plant taxonomy. Background Classification systems serve the purpose of grouping organisms by characteristics common to each group. Plants are distinguished from animals by various trai ...

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. 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''. This genus contains the following species: *'' Hesperocyparis abramsiana'' (C. B. Wolf) Bartel *''Hesperocyparis arizonica'' (Greene) Bartel *''Hesperocyparis baker ...

Rancho La Brea
Rancho La Brea was a Mexican land grant in present-day Los Angeles County, California, given in 1828 to Antonio Jose Rocha and Nemisio Dominguez by José Antonio Carrillo, the alcalde of Los Angeles. Rancho La Brea consisted of one square league of land of what is now Wilshire's Miracle Mile, Hollywood, and parts of West Hollywood. The grant included the famous La Brea Tar Pits. History The title awarded by the alcalde in 1828 was confirmed by José María de Echeandía, governor of Alta California; in 1840, it was reconfirmed by Governor Juan Alvarado. With the cession of California to the United States after the Mexican–American War, the 1848 Treaty of Guadalupe Hidalgo provided that the land grants would be honored. As required by the Land Act of 1851, a claim was filed by Antonio José Rocha, José Jorge Rocha, and Josefa de la Merced de Jordan with the Public Land Commission in 1852, but it was rejected in 1860. As a lawyer and surveyor, Henry Hancock worked for the ...

Drakes Bay
Drakes Bay (Coast Miwok: ''Tamál-Húye'') is a wide bay named so by U.S. surveyor George Davidson in 1875 along the Point Reyes National Seashore on the coast of northern California in the United States, approximately northwest of San Francisco at approximately 38 degrees north latitude. The bay is approximately wide. It is formed on the lee side of the coastal current by Point Reyes. The bay is named after Sir Francis Drake and has long been considered Drake's most likely landing spot on the west coast of North America during his circumnavigation of the world by sea in 1579. An alternative name for this bay is Puerto De Los Reyes. The bay is fed by Drake's Estero, an expansive estuary on the Point Reyes peninsula. The estuary is protected by Estero de Limantour State Marine Reserve & Drakes Estero State Marine Conservation Area. Point Reyes State Marine Reserve & Point Reyes State Marine Conservation Area lie within Drakes Bay. Like underwater parks, these marine pr ...
