Ceratozamia Sabatoi
''Ceratozamia sabatoi'' is a species of plant in the family Zamiaceae. It is endemic to Mexico, where it occurs in the states of Hidalgo and Querétaro. It is known from only two localities, one of which is degraded by agriculture and grazing. This cycad is generally palm-like in appearance. The trunk is rounded, becoming more cylindrical with age to a maximum length of 25 centimeters. It bears 2 to 6 prickly leaves each up to 80 centimeters long and made up of 12 to 136 leaflets.Vovides, A. P., Torres, M. V., Schutzman, B., & Iglesias, C. G.

Plant
Plants are predominantly photosynthetic eukaryotes of the kingdom Plantae. Historically, the plant kingdom encompassed all living things that were not animals, and included algae and fungi; however, all current definitions of Plantae exclude the fungi and some algae, as well as the prokaryotes (the archaea and bacteria). By one definition, plants form the clade Viridiplantae (Latin name for "green plants") which is sister of the Glaucophyta, and consists of the green algae and Embryophyta (land plants). The latter includes the flowering plants, conifers and other gymnosperms, ferns and their allies, hornworts, liverworts, and mosses. Most plants are multicellular organisms. Green plants obtain most of their energy from sunlight via photosynthesis by primary chloroplasts that are derived from endosymbiosis with cyanobacteria. Their chloroplasts contain chlorophylls a and b, which gives them their green color. Some plants are parasitic or mycotrophic and have lost the ...

Meliosma Alba
''Meliosma'' is a genus of flowering plants in the family Sabiaceae, native to tropical to warm temperate regions of southern and eastern Asia and the Americas. It is traditionally considered to contain about 100 species; some botanists take a much more conservative view accepting only 20-25 species as distinct. They are trees or shrubs, growing to 10–45 m tall. Fossil evidence shows the genus formerly had a much wider range in the Northern Hemisphere, including Europe and central Asia until the late Pliocene ice ages, and somewhat earlier in North America. Meliosma symbolises Peruvian cloud forest plants which, once did not have even a single species of Sabiaceae. Now,at least 17 species of Meliosma are known from Peru. The Indian awlking (''Choaspes benjaminii'') is one of the Lepidoptera whose caterpillars feed on ''Meliosma''; they have been found on '' M. pungens'', '' rhoifolia'', '' M. rigida'', and '' M. squamulata''. Selected species Asia * ''Meliosma angustifoli ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Endangered Biota Of Mexico
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] |
Endangered Plants
As of September 2016, the International Union for Conservation of Nature (IUCN) lists 3654 endangered plant species. 17% of all evaluated plant species are listed as endangered. The IUCN also lists 99 subspecies and 101 varieties as endangered. No subpopulations of plants have been evaluated by the IUCN. For a species to be considered endangered by the IUCN it must meet certain quantitative criteria which are designed to classify taxa facing "a very high risk of exintction". An even higher risk is faced by ''critically endangered'' species, which meet the quantitative criteria for endangered species. Critically endangered plants are listed separately. There are 6147 plant species which are endangered or critically endangered. Additionally 1674 plant species (7.6% of those evaluated) are listed as '' data deficient'', meaning there is insufficient information for a full assessment of conservation status. As these species typically have small distributions and/or populations, t ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Flora Of Querétaro
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 Phy ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Endemic Flora Of Mexico
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] |
Ceratozamia
''Ceratozamia'' is a genus of New World cycads in the family Zamiaceae. The genus contains 27 known currently living species and one or two fossil species. Most species are endemic to mountainous areas of Mexico, while few species extend into the mountains of Guatemala, Honduras and Belize. The genus name comes from the Greek ''ceras'', meaning horn, which refers to the paired, spreading horny projections on the male and female sporophylls of all species. Many species have extremely limited ranges, and almost all described species are listed as vulnerable, endangered, or critically endangered by the IUCN Red List. The whole genus is listed under CITES Appendix I / EU Annex A, which prohibits international trade in specimens of these species except when the purpose of the import is not commercial, for instance for scientific research. Illegal plant poaching has posed a major threat to ''Ceratozamia'' species. Description The plants are dioecious, with a globose or cylindrical st ...

Zamiaceae
The Zamiaceae are a family of cycads that are superficially palm or fern-like. They are divided into two subfamilies with eight genera and about 150 species in the tropical and subtropical regions of Africa, Australia and North and South America. The Zamiaceae, sometimes known as zamiads, are perennial, evergreen, and dioecious. They have subterranean to tall and erect, usually unbranched, cylindrical stems, and stems clad with persistent leaf bases (in Australian genera). Their leaves are simply pinnate, spirally arranged, and interspersed with cataphylls. The leaflets are sometimes dichotomously divided. The leaflets occur with several sub-parallel, dichotomously branching longitudinal veins; they lack a mid rib. Stomata occur either on both surfaces or undersurface only. Their roots have small secondary roots. The coralloid roots develop at the base of the stem at or below the soil surface. Male and female sporophylls are spirally aggregated into determinate cones that gro ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Carya Ovata
''Carya ovata'', the shagbark hickory, is a common hickory in the Eastern United States and southeast Canada. It is a large, deciduous tree, growing well over tall, and can live more than 350 years. The tallest measured shagbark, located in Savage Gulf, Tennessee, is over tall . Mature shagbarks are easy to recognize because, as their name implies, they have shaggy bark. This characteristic is, however, only found on mature trees; young specimens have smooth bark. The shagbark hickory's nut is edible and has a very sweet taste. The leaves are long, pinnate, with five (rarely three or seven) leaflets, the terminal three leaflets much larger than the basal pair. The shagbark hickory is monoecious. Staminate flowers are borne on long-stalked catkins at the tip of old wood or in the axils of the previous season's leaves. Pistillate flowers occur in short terminal spikes. The fruit is a drupe long, an edible nut with a hard, bony shell, contained in a thick, green four-sectione ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
