Cupressus Glabra
''Cupressus arizonica'' var. ''glabra'', known as the Arizona smooth bark cypress or smooth Arizona cypress, is a conifer native to the American Southwest, with a range stretching over the canyons and slopes in a somewhat wide vicinity around Sedona, Arizona. It was first described by George Bishop Sudworth in 1910. It is distinguished from ''Cupressus arizonica'' var. ''arizonica'' by its very smooth, non-furrowed bark which can appear in shades of pink, cherry, and grey. It is often seen in cultivation, as unlike the Monterey cypress, it has proved almost immune to cypress canker Cypress canker is a disease affecting ''Cupressus'' species, caused by one of several species of fungus in the genus ''Seiridium''.

Sedona, Arizona
Sedona is a city that straddles the county line between Coconino and Yavapai counties in the northern Verde Valley region of the U.S. state of Arizona. As of the 2010 census, its population was 10,031. It is within the Coconino National Forest. Sedona's main attraction is its array of red sandstone formations. The formations appear to glow in brilliant orange and red when illuminated by the rising or setting sun. The red rocks form a popular backdrop for many activities, ranging from spiritual pursuits to the hundreds of hiking and mountain biking trails. Sedona is also the home to the nationally recognized McDonald's with turquoise arches, instead of the traditional Golden Arches. Sedona was named after Sedona Arabella Miller Schnebly (1877–1950), the wife of Theodore Carlton Schnebly, the city's first postmaster. She was celebrated for her hospitality and industriousness. Her mother, Amanda Miller, claimed to have made the name up because "it sounded pretty". Histor ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Cupressus Arizonica
''Cupressus arizonica'', the Arizona cypress, is a North American species of tree in the cypress family Cupressaceae, native to the southwestern United States and Mexico. Populations may be scattered rather than in large, dense stands. Description ''Cupressus arizonica'' is a coniferous evergreen tree with a conic to ovoid-conic crown. It grows to heights of , and its trunk diameter reaches . The foliage grows in dense sprays, varying from dull gray-green to bright glaucous blue-green. The leaves are scale-like, 2–5 mm long, and produced on rounded (not flattened) shoots. The seed cones are globose to oblong, 15–33 mm long, with 6 or 8 (rarely 4 or 10) scales, green at first, maturing gray or gray-brown about 20–24 months after pollination. The cones remain closed for many years, only opening after the bearing branch is killed (in a wildfire or otherwise), allowing the seeds to colonize the bare ground exposed by the fire. The male cones are 3–5 mm long, and ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Cupressus 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, and ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Cypress Canker
Cypress canker is a disease affecting ''Cupressus'' species, caused by one of several species of fungus in the genus ''Seiridium''. Infection causes die-back of twigs and branches in susceptible cypress trees, with rapidly increasing amounts of damage and the death of the tree. History The first epidemic of cypress canker was recorded in California in 1928, with Monterey cypress (''Cupressus macrocarpa'') being affected. Within a few years the local populations of this tree had been killed. The species is widely traded as an ornamental tree and the disease had soon spread worldwide, probably with nursery stock. Within five decades the disease had reached New Zealand, France, Chile, Italy, Argentina, Greece, most of Europe, Canada, North Africa, South Africa and Australia. The causal agent of this pandemic spread was the pathogenic fungus ''Seiridium cardinale'', with '' Seiridium cupressi'' and '' Seiridium unicorne'' sometimes being involved, but being less aggressive; other pat ...

Cupressus
''Cupressus'' is one of several genera of evergreen conifers within the family Cupressaceae that have the common name cypress; for the others, see cypress. It is considered a 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 ''cipres'' from the Latin ''cyparissus'', which is the latinisation of the Greek κυπάρισσος (''kypárissos''). Taxonomy There has long been significant uncertainty about the New World members of ''Cupressus'', with several studies recovering them as forming a distinct clade from the Old World members. A 2021 molecular study found ''Cupressus'' to be the sister genus to ''Juniperus'', whereas the western members (classified in '' Callitropsis'' and ''Hesperocyparis'') were found to be sister to ''Xanthocyparis''. Description They are evergreen trees or large shrubs, growing to 5–40 m tall. The leaves are scale-lik ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Flora Of Arizona
Flora is all the plant life present in a particular region or time, generally the naturally occurring (indigenous) native plants. Sometimes bacteria and fungi are also referred to as flora, as in the terms '' gut flora'' or '' skin flora''. Etymology The word "flora" comes from the Latin name of Flora, the goddess of plants, flowers, and fertility in Roman mythology. The technical term "flora" is then derived from a metonymy of this goddess at the end of the sixteenth century. It was first used in poetry to denote the natural vegetation of an area, but soon also assumed the meaning of a work cataloguing such vegetation. Moreover, "Flora" was used to refer to the flowers of an artificial garden in the seventeenth century. The distinction between vegetation (the general appearance of a community) and flora (the taxonomic composition of a community) was first made by Jules Thurmann (1849). Prior to this, the two terms were used indiscriminately.Thurmann, J. (1849). ''Essai de ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Endemic Flora Of The United States
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 s ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Trees Of The Southwestern United States
In botany, a tree is a perennial plant with an elongated stem, or trunk, usually supporting branches and leaves. In some usages, the definition of a tree may be narrower, including only woody plants with secondary growth, plants that are usable as lumber or plants above a specified height. In wider definitions, the taller palms, tree ferns, bananas, and bamboos are also trees. Trees are not a taxonomic group but include a variety of plant species that have independently evolved a trunk and branches as a way to tower above other plants to compete for sunlight. The majority of tree species are angiosperms or hardwoods; of the rest, many are gymnosperms or softwoods. Trees tend to be long-lived, some reaching several thousand years old. Trees have been in existence for 370 million years. It is estimated that there are some three trillion mature trees in the world. A tree typically has many secondary branches supported clear of the ground by the trunk. This trunk typically co ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
