Dracaena Ajgal
''Dracaena ajgal'' is a species of flowering plant in the family Asparagaceae. It is a tree native to southwestern Morocco. It grows on steep rocky slopes of quarzitic and hard ultramafic rock in the western Anti-Atlas range at approximately 700 metres elevation, in the transition between semi-arid Argania– ''Olea europaea'' subsp. ''maroccana'' and Mediterranean-climate ''Quercus rotundifolia''–'' Genista segonnei'' plant communities.Rivas-Martínez, S., V.M. J. Molero, J.M. Marfíl, & G. Benítez, 2020.

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 ...

Flowering Plant
Flowering plants are plants that bear flowers and fruits, and form the clade Angiospermae (). The term angiosperm is derived from the Ancient Greek, Greek words (; 'container, vessel') and (; 'seed'), meaning that the seeds are enclosed within a fruit. The group was formerly called Magnoliophyta. Angiosperms are by far the most diverse group of Embryophyte, land plants with 64 Order (biology), orders, 416 Family (biology), families, approximately 13,000 known Genus, genera and 300,000 known species. They include all forbs (flowering plants without a woody Plant stem, stem), grasses and grass-like plants, a vast majority of broad-leaved trees, shrubs and vines, and most aquatic plants. Angiosperms are distinguished from the other major seed plant clade, the gymnosperms, by having flowers, xylem consisting of vessel elements instead of tracheids, endosperm within their seeds, and fruits that completely envelop the seeds. The ancestors of flowering plants diverged from the commo ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Asparagaceae
Asparagaceae (), known as the asparagus family, is a family of flowering plants, placed in the order Asparagales of the monocots. The family name is based on the edible garden asparagus, '' Asparagus officinalis''. This family includes both common garden plants as well as common houseplants. The garden plants include asparagus, yucca, bluebell, lily of the valley, and hosta, and the houseplants include snake plant, corn cane, spider plant, and plumosus fern. The Asparagaceae is a morphologically heterogenous family with the included species varying widely in their appearance and growth form. It has a cosmopolitan distribution, with genera and species contained in the family native to all continents except Antarctica. Taxonomy Early taxonomy The plant family Asparagaceae was first named, described, and published in Genera Plantarum in 1789 by the French botanist Antoine Laurent de Jussieu, who is particularly noted for his work in developing the concept of pl ...

Anti-Atlas
The Anti-Atlas, also known as Lesser Atlas or Little Atlas, is a mountain range in Morocco, a part of the Atlas Mountains in the northwest of Africa. The Anti-Atlas extends from the Atlantic Ocean in the southwest toward the northeast, to the heights of Ouarzazate and further east to the city of Tafilalt, altogether a distance of approximately 500 km. The range borders on the Sahara to the south."Anti-Atlas" (or Jebel Saghru), ''The Encyclopædia Britannica'', 1910. In some contexts, the Anti-Atlas is considered separate from the Atlas Mountains system, as the prefix "anti" (i.e. opposite) implies. Geography The summits of the Anti-Atlas reach average heights of , with a few peaks reaching higher. To the north lies a plateau at 1700–1800 m in height. To the south lie the Sahara highlands at approximately 700 m. On the heights of Ouarzazate, the massif is cut through by the Draa valley, opening towards the south. The range is strongly fissured, particularly in a sout ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Argania
''Sideroxylon spinosum'', known as argan (), synonym ''Argania spinosa'', is a species of flowering plant. It is a tree Endemism, endemic to the calcareous semi-desert Sous valley of southwestern Morocco and to the region of Tindouf Province, Tindouf in southwestern Algeria. Argan trees grow to high and live up to approximately 200 years. They are thorny, with gnarled trunks and wide spreading crown. The crown has a circumference of up to and the branches may lean towards the ground. Name The former scientific name ''Argania'' was derived from ''argan'', the name of the tree in Shilha language, Shilha, the Berber languages, Berber language which is spoken by the majority of the people living in the areas where the tree is endemic. Shilha Berber has a rich vocabulary for the various parts of the fruit, its stages of ripeness, and its harvesting and processing. The oil is called argan oil. In medieval Arabic pharmacological sources, the tree is known as ''harjān'', a distortion ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Olea Europaea
The olive, botanical name ''Olea europaea'' ("European olive"), is a species of subtropical evergreen tree in the family Oleaceae. Originating in Asia Minor, it is abundant throughout the Mediterranean Basin, with wild subspecies in Africa and western Asia; modern cultivars are traced primarily to the Near East, Aegean Sea, and Strait of Gibraltar. The olive is the type species for its genus, '' Olea'', and lends its name to the Oleaceae plant family, which includes species such as lilac, jasmine, forsythia, and ash. The olive fruit is classed botanically as a drupe, similar to the cherry or peach. The term oil—now used to describe any viscous water-insoluble liquid—was virtually synonymous with olive oil, the liquid fat made from olives. The olive has deep historical, economic, and cultural significance in the Mediterranean; Georges Duhamel remarked that the "Mediterranean ends where the olive tree no longer grows". Among the oldest fruit trees domesticated ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Quercus Rotundifolia
''Quercus rotundifolia'', the holm oak or ballota oak, is an evergreen oak native to the western Mediterranean region, with the majority of the population in the Iberian Peninsula and minor populations in Northwest Africa. The species was first described by Jean-Baptiste Lamarck in 1785. It is the typical species of the Iberian ''dehesa'' or ''montado'', where its sweet-astringent acorns are a source of food for livestock, particularly the Iberian pig. Its acorns have also been used for human nourishment since the Neolithic era (7,000 BC). It is placed in section ''Ilex''. Some authors described it as a subspecies of ''Quercus ilex''. Description ''Quercus rotundifolia'' is a medium to large tree, usually in height, but can reach up to with a large, dense, rounded canopy. It has small, leathery, dark-green leaves with a glaucous, densely pubescent underside usually suborbicular to elliptical or lanceolate and are generally spiny to dentate on a younger tree. It has a semi- ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Genista Segonnei
''Genista'' is a genus of flowering plants in the legume family Fabaceae, native to open habitats such as moorland and pasture in Europe and western Asia. They include species commonly called broom, though the term may also refer to other genera, including ''Cytisus'' and ''Chamaecytisus''. Brooms in other genera are sometimes considered synonymous with ''Genista'': ''Echinospartum'', ''Retama'', ''Spartium'', ''Stauracanthus'', and ''Ulex''. Description They are mainly deciduous shrubs and trees, often with brush-like foliage, often spiny to deter browsing, and masses of small, pea-like yellow blooms which are sometimes fragrant. Many of the species have flowers that open explosively when alighted on by an insect, the style flying through the upper seam of the keel and striking the underside of the insect, followed by a shower of pollen that coats the insect. The name of the Plantagenet royal line, which reigned in England from 1154 to 1485, is derived from this genus, being ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Dracaena Draco
''Dracaena draco'', the Canary Islands dragon tree or drago, is a subtropics, subtropical tree in the genus ''Dracaena (plant), Dracaena'', native plant, native to the Canary Islands, Cape Verde, Madeira, Mount Adad Madani, western Morocco, and possibly introduced into the Azores. It was first described by Carl Linnaeus in 1762 as ''Asparagus draco''. In 1767 he assigned it to the new genus, ''Dracaena (plant), Dracaena''. A related tree of similar appearance, the Socotra dragon tree ''Dracaena cinnabari'', grows on the island of Socotra, Yemen, more than 7000 km from the Canary Islands. Description ''Dracaena draco'' is an evergreen long lived tree capable of exceeding in height and having a trunk of or more in circumference, starting with a smooth bark that evolves to a more rough texture as it ages. The "dragon tree" is a Monocot, with a branching growth pattern currently placed in the asparagus family (Asparagaceae, subfamily Nolinoidae). When young it has a single stem ...

Dracaena (plant)
''Dracaena'' () is a genus of about 200 species of trees and succulent shrubs. The formerly accepted genera '' Pleomele'' and '' Sansevieria'' are now included in ''Dracaena''. In the APG IV classification system, it is placed in the family Asparagaceae, subfamily Nolinoideae (formerly the family Ruscaceae). It has also formerly been separated (sometimes with '' Cordyline'') into the family Dracaenaceae or kept in the Agavaceae (now Agavoideae). The name ''dracaena'' is derived from the romanized form of the Ancient Greek – ''drakaina'', "female dragon". The majority of the species are native to Africa and the Canary Islands, southern Asia through to northern Australia, with two species in tropical Central America. Description Species of ''Dracaena'' have a secondary thickening meristem in their trunk, termed Dracaenoid thickening by some authors, which is quite different from the thickening meristem found in dicotyledonous plants. This characteristic is shared with me ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Endemic Flora Of Morocco
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 ...
