Persea Barbujana
''Persea barbujana'', the Canary laurel or barbusano, is a species of tree in the laurel family, Lauraceae. It is endemic to the Macaronesian islands of Madeira (incl. Porto Santo) and the Canary Islands. It is often placed as the sole species in genus '' Apollonias''. Molecular phylogenic analyses found that the species is nested within the genus ''Persea,'' which also includes the Macaronesian endemic ''Persea indica''. The La Gomera La Gomera () is one of Spain's Canary Islands, in the Atlantic Ocean off the coast of Africa. With an area of , it is the third-smallest of the archipelago's eight main islands. It belongs to the province of Santa Cruz de Tenerife. La Gomer ... subspecies is distinct and endangered.

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). The database contains information on the world's flora gathered from 250 years of botanical research. It aims to make available data from projects that no longer have an online ...

Persea
''Persea'' is a genus of about 111 species of evergreen trees belonging to the laurel family, Lauraceae. The best-known member of the genus is the avocado, ''P. americana'', widely cultivated in subtropical regions for its large, edible fruit. Overview They are medium-size trees, tall at maturity. The leaf, leaves are simple, lanceolate to broad lanceolate, varying with species from long and broad, and arranged spirally or alternately on the stems. The flowers are in short panicles, with six small greenish-yellow perianth segments long, nine stamens and an ovary with a single embryo. The fruit is an oval or pear-shaped berry (botany), berry, with a fleshy outer covering surrounding the single seed; size is very variable among the species, from in e.g. ''P. indica'', up to in some cultivars of ''P. americana''. Distribution and ecology The species of ''Persea'' have a disjunct distribution, with about 109 Neotropical realm, Neotropical species, ranging from Argentina and Ch ...

Plants Described In 1801
Plants are the eukaryotes that form the kingdom Plantae; they are predominantly photosynthetic. This means that they obtain their energy from sunlight, using chloroplasts derived from endosymbiosis with cyanobacteria to produce sugars from carbon dioxide and water, using the green pigment chlorophyll. Exceptions are parasitic plants that have lost the genes for chlorophyll and photosynthesis, and obtain their energy from other plants or fungi. Most plants are multicellular, except for some green algae. Historically, as in Aristotle's biology, the plant kingdom encompassed all living things that were not animals, and included algae and fungi. Definitions have narrowed since then; current definitions exclude fungi and some of the algae. By the definition used in this article, plants form the clade Viridiplantae (green plants), which consists of the green algae and the embryophytes or land plants (hornworts, liverworts, mosses, lycophytes, ferns, conifers and other gymnosperm ...

Flora Of Madeira
Flora (: floras or florae) is all the plant life present in a particular region or time, generally the naturally occurring (indigenous) native plants. The corresponding term for animals is ''fauna'', and for fungi, it is ''funga''. Sometimes bacteria and fungi are also referred to as flora as in the terms ''gut flora'' or ''skin flora'' for purposes of specificity. 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 ...

Endemic Flora Of Macaronesia
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 becoming ...

La Gomera
La Gomera () is one of Spain's Canary Islands, in the Atlantic Ocean off the coast of Africa. With an area of , it is the third-smallest of the archipelago's eight main islands. It belongs to the province of Santa Cruz de Tenerife. La Gomera is the third least populous of the eight main Canary Islands, with 22,361 inhabitants at the start of 2023.

Persea Indica
''Persea indica'' is a large, evergreen tree in the laurel family (Lauraceae), native to humid uplands on Madeira and the Canary Islands in the North Atlantic. It belongs to the genus '' Persea'', a group of evergreen trees including the avocado. It is threatened by habitat loss. It has been introduced to a number of islands in the nearby Azores. Overview Fossil evidence indicates that genus '' Persea'' originated in West Africa during the Paleocene, and spread to Asia, South America, Europe and North America. It is thought that the gradual drying of Africa, west Asia, and the Mediterranean from the Oligocene to the Pleistocene, and the glaciation of Europe during the Pleistocene, caused the extinction of the genus across these regions, resulting in the present distribution. Genus '' Persea'' disappeared from increasingly xerophytic Africa, starting with the formation of the Benguela Current. It is extinct in Africa, save for ''P. indica'', which survives in the cloud forests ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Apollonias
''Apollonias'' is a genus of flowering plants belonging to the laurel family, Lauraceae. The genus includes from zero to 10 species of evergreen trees and shrubs, depending on circumscription. Recent studies transferred the majority of species to ''Beilschmiedia''. A recent phylogenetic study found that ''Apollonias barbjuana'', native to the Canary Islands and Madeira, is nested in genus ''Persea'', and has been renamed ''Persea barbujana''. '' Apollonias arnottii'', which is endemic to the Western Ghats of India, is considered an unplaced taxon by Plants of the World Online. Species * '' A. arnottii'' ( unplaced) – Western Ghats * ''A. barbujana'' (syn.

Porto Santo Island
Porto Santo Island () is a Portuguese island and municipality northeast of Madeira Island in the North Atlantic Ocean; it is the northernmost and easternmost island of the archipelago of Madeira, located in the Atlantic Ocean west of Europe and Africa. The municipality of Porto Santo occupies the entire island and small neighbouring islands. It was elevated to city status on 6 August 1996. The sole parish of the municipality is also named Porto Santo. The population in 2011 was 5,483, in an area of 42.59 km2. The main settlement on the island is Vila Baleira. History It appears that some knowledge of Atlantic islands, such as Madeira, existed before the discovery and settlement of these lands, as the islands appear on maps as early as 1339. From a portolan dating to 1351, and preserved in Florence, Italy, it would appear that the islands of Madeira had been discovered long before being claimed by the Portuguese expedition of 1418.
