Aloe Squarrosa
''Aloe squarrosa'' is a species of flowering plant in the Asphodelaceae family. It is from the island of Socotra, Yemen. Description ''Aloe squarrosa'' has smooth, green, spotted leaves that curve backwards. These recurved leaves are kept only around the head or top of each stem, with dead leaves falling off the lower parts of the stem. The inflorescence is short and simple, and the flowers are light orange with green tips. It is relatively rare in cultivation. It is frequently confused with '' Aloe juvenna'' from Kenya. However the more common ''Aloe juvenna'' has shorter, straight, non-recurved triangular leaves and grows long stems, with the leaves retained all along the stems.

John Gilbert Baker
John Gilbert Baker (13 January 1834 – 16 August 1920) was an England, English botanist. His son was the botanist Edmund Gilbert Baker (1864–1949). Biography Baker was born in Guisborough in North Yorkshire, the son of John and Mary (née Gilbert) Baker, and died in Kew. He was educated at Quaker schools at Ackworth School and Bootham School, York. He then worked at the library and herbarium of the Royal Botanic Gardens, Kew between 1866 and 1899, and was keeper of the herbarium from 1890 to 1899.

Taxonomy Articles Created By Polbot
280px, Generalized scheme of taxonomy Taxonomy is a practice and science concerned with classification or categorization. Typically, there are two parts to it: the development of an underlying scheme of classes (a taxonomy) and the allocation of things to the classes (classification). Originally, taxonomy referred only to the classification of organisms on the basis of shared characteristics. Today it also has a more general sense. It may refer to the classification of things or concepts, as well as to the principles underlying such work. Thus a taxonomy can be used to organize species, documents, videos or anything else. A taxonomy organizes taxonomic units known as "taxa" (singular "taxon"). Many are hierarchies. One function of a taxonomy is to help users more easily find what they are searching for. This may be effected in ways that include a library classification system and a search engine taxonomy. Etymology The word was coined in 1813 by the Swiss botanist A ...

Endemic Flora Of Socotra
Endemism is the state of a species being found only 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 also be referred to as an ''endemism'' or, in scientific literature, as an ''endemite''. Similarly, many species found in the Western ghats of India are examples of endemism. Endemism is an important concept in conservation biology for measuring biodiversity in a particular place and evaluating the risk of extinction for species. Endemism is also of interest in evolutionary biology, because it provides clues about how changes in the environment cause species to undergo range shifts (potentially expanding their range into a larger area or becomin ...

Aloe
''Aloe'' (; also written ''Aloë'') is a genus containing over 650 species of flowering plant, flowering succulent plant, succulent plants.WFO (2022): Aloe L. Published on the Internet;http://www.worldfloraonline.org/taxon/wfo-4000001341. Accessed on: 06 Nov 2022 The most widely known species is ''Aloe vera'', or "true aloe". It is called this because it is cultivated as the standard source for assorted pharmaceutical purposes. Other species, such as ''Aloe ferox'', are also cultivated or harvested from the wild for similar applications. The APG IV system (2016) places the genus in the family Asphodelaceae, subfamily Asphodeloideae. Within the subfamily it may be placed in the tribe Aloeae.Stevens, P.F. (2001 onwards).Asphodelaceae. ''Angiosperm Phylogeny Website''. Retrieved 2016-06-09. In the past, it has been assigned to the family Aloaceae (now included in the Asphodeloidae) or to a broadly Circumscription (taxonomy), circumscribed family Liliaceae (the lily family). The ...

Habitat Destruction
Habitat destruction (also termed habitat loss or habitat reduction) occurs when a natural habitat is no longer able to support its native species. The organisms once living there have either moved elsewhere, or are dead, leading to a decrease in biodiversity and species numbers. Habitat destruction is in fact the leading cause of biodiversity loss and species extinction worldwide. Humans contribute to habitat destruction through the use of natural resources, agriculture, industrial production and urbanization (urban sprawl). Other activities include mining, logging and trawling. Environmental factors can contribute to habitat destruction more indirectly. Geological processes, climate change, introduction of invasive species, ecosystem nutrient depletion, water and noise pollution are some examples. Loss of habitat can be preceded by an initial habitat fragmentation. Fragmentation and loss of habitat have become one of the most important topics of research in ecology as the ...

Habitat
In ecology, habitat refers to the array of resources, biotic factors that are present in an area, such as to support the survival and reproduction of a particular species. A species' habitat can be seen as the physical manifestation of its ecological niche. Thus "habitat" is a species-specific term, fundamentally different from concepts such as Biophysical environment, environment or vegetation assemblages, for which the term "habitat-type" is more appropriate. The physical factors may include (for example): soil, moisture, range of temperature, and Luminous intensity, light intensity. Biotic index, Biotic factors include the availability of food and the presence or absence of Predation, predators. Every species has particular habitat requirements, habitat generalist species are able to thrive in a wide array of environmental conditions while habitat specialist species require a very limited set of factors to survive. The habitat of a species is not necessarily found in a ge ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Aloe Juvenna
''Aloe juvenna'' (tiger-tooth aloe) is a species of plant in the genus ''Aloe''. It is popular in cultivation but extremely rare in its natural habitat in Kenya. Distribution and habitat It is Endemism, endemic to Kenya in East Africa. Here it is restricted to a small rocky area in the mountainous south west of the country, near the border with Tanzania. Discovery and history in cultivation It has long been common in cultivation, but its origin was not known. The first recorded cultivated specimens were in South Africa, but although there were rumours that it had come from Kenya, its origins were a mystery even then. It was first believed to be a juvenile Aloe, due to its small size, and it was labelled "juvenna" ("juvenile") for this reason. However that label eventually became its formal name. Later, it was thought to be a hybrid perhaps of ''Aloe distans'' with ''Haworthia coarctata'' or a species of ''Astroloba''. It underwent genetic testing in the 1970s and, when it wa ...
