Aquilegia Ballii
''Aquilegia ballii'' is a perennial flowering plant in the family Ranunculaceae, endemic to Morocco. Description ''Aquilegia ballii'' is a perennial herb growing to high. The rhizome is thick and covered with the remains of previous years' foliage. The stem is robust, smooth, and branched towards the top; the branches may be pubescent or glandular. The basal leaves are green on their upper surface and pale green on the underside, biternate or triternate (i.e. with three stalks, each with three leaflets that divide into three lobes), and have pubescent leaf stalks up to long. The flowers have white or slightly bluish sepals long and white petals long with blue, slightly curved nectar spurs of length. Both the sepals and petals are green at the tip and sparsely hairy. The anthers are bright yellow. Taxonomy ''Aquilegia ballii'' was described by René Verriet de Litardière and René Maire as the variety ''ballii'' of ''Aquilegia vulgaris'' in 1930. It was reassessed as a subs ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Glossary Of Leaf Morphology
The following terms are used to describe leaf plant morphology, morphology in the description and taxonomy (biology), taxonomy of plants. Leaves may be simple (that is, the leaf blade or 'lamina' is undivided) or compound (that is, the leaf blade is divided into two or more leaflet (botany), leaflets). The edge of the leaf may be regular or irregular, and may be smooth or have hair, bristles, or spines. For more terms describing other aspects of leaves besides their overall morphology see the leaf#Terminology, leaf article. The terms listed here all are supported by technical and professional usage, but they cannot be represented as mandatory or undebatable; readers must use their judgement. Authors often use terms arbitrarily, or coin them to taste, possibly in ignorance of established terms, and it is not always clear whether because of ignorance, or personal preference, or because usages change with time or context, or because of variation between specimens, even specimens from ...

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 ...

Aquilegia
''Aquilegia'', commonly known as columbines, is a genus of perennial flowering plants in the family Ranunculaceae (buttercups). The genus includes between 80 and 400 taxa (described species and subspecies) with natural Species distribution, ranges across the Northern Hemisphere. Natural and Introduced species, introduced populations of ''Aquilegia'' exist on all continents but Antarctica. Known for their high physical variability and ease of Hybridization in perennial plants, hybridization, columbines are popular garden plants and have been used to create many Cultivar, cultivated varieties. ''Aquilegia'' typically possess stiff stems and leaves divide into multiple Leaflet (botany), leaflets. Columbines often have colorful flowers with five sepals and five petals. The petals generally feature nectar spurs which differ in lengths between species. In North America, morphological variations in spurs evolved to suit different pollinators. Some species and varieties of columbines are ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

IUCN Red List
The International Union for Conservation of Nature (IUCN) Red List of Threatened Species, also known as the IUCN Red List or Red Data Book, founded in 1964, is an inventory of the global conservation status and extinction risk of biological species. A series of Regional Red Lists, which assess the risk of extinction to species within a political management unit, are also produced by countries and organizations. The goals of the Red List are to provide scientifically based information on the status of species and subspecies at a global level, to draw attention to the magnitude and importance of threatened biodiversity, to influence national and international policy and decision-making, and to provide information to guide actions to conserve biological diversity. Major species assessors include BirdLife International, the Institute of Zoology (the research division of the Zoological Society of London), the World Conservation Monitoring Centre, and many Specialist Groups w ...

High Atlas
The High Atlas, also called the Grand Atlas, is a mountain range in central Morocco, North Africa, the highest part of the Atlas Mountains. The High Atlas rises in the west at the Atlantic Ocean and stretches in an eastern direction to the Moroccan-Algerian border. At the Atlantic and to the southwest the range drops abruptly and makes an impressive transition to the coast and the Anti-Atlas range. To the north, in the direction of Marrakech, the range descends less abruptly. The range includes Jbel Toubkal, which at is the highest in the range and lies in Toubkal National Park. The range serves as a weather system barrier in Morocco running east–west and separating the Sahara from the Mediterranean and continental zones to the north and west. In the higher elevations of the massif, snow falls regularly, allowing winter sports. Snow lasts well into late spring in the High Atlas, mostly on the northern faces of the range. On the Western High Atlas, there is Oukaïmeden, o ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
John Ball (naturalist)
John Ball (20 August 1818 – 21 October 1889) was an Irish politician, naturalist and Alpine traveller. Background and education Ball was born in Dublin, the eldest son of Nicholas Ball, judge of the Court of Common Pleas (Ireland) and his wife Jane Sherlock. He was educated at Oscott College near Birmingham, and at Christ's College, Cambridge, where he was 41st Wrangler but as a Roman Catholic could not be admitted to a BA degree. He showed in his early years a taste for natural science, particularly botany; and after leaving Cambridge he travelled in Switzerland and elsewhere in Europe and North Africa, studying his favourite pursuits, and contributing papers on botany and the Swiss glaciers to scientific periodicals. Political career In 1846 Ball was made an assistant poor-law commissioner, but resigned in 1847, and in 1848 stood unsuccessfully as a parliamentary candidate for Sligo. In 1849 he was appointed second poor-law commissioner, but resigned in 1852 and succ ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Binomial Nomenclature
In taxonomy, binomial nomenclature ("two-term naming system"), also called binary nomenclature, is a formal system of naming species of living things by giving each a name composed of two parts, both of which use Latin grammatical forms, although they can be based on words from other languages. Such a name is called a binomial name (often shortened to just "binomial"), a binomen, name, or a scientific name; more informally, it is also called a Latin name. In the International Code of Zoological Nomenclature (ICZN), the system is also called nomenclature, with an "n" before the "al" in "binominal", which is a typographic error, meaning "two-name naming system". The first part of the name – the '' generic name'' – identifies the genus to which the species belongs, whereas the second part – the specific name or specific epithet – distinguishes the species within the genus. For example, modern humans belong to the genus ''Homo'' and within this genus to the species ''Hom ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Aquilegia Vulgaris
''Aquilegia vulgaris'' is a species of perennial flowering plant of the genus ''Aquilegia'' (columbine) in the family Ranunculaceae. Commonly called the common columbine, European crowfoot, and granny's bonnet, it presently possesses the most expansive range and greatest morphological variability in its genus. The current wild range of ''A. vulgaris'' includes its native range in Europe as well as introduced populations in Asia, Oceania, North America (where it has become naturalized), and South America. The wild form of ''A. vulgaris'' can grow flowering stems that tall from and often form a bushy clump at its base. In their native range, the species blooms from May to June. The flowers, with diameters measuring up to across, are typically blue or purple and possess petals with structures known as nectar spurs. Associated with fertility goddesses in ancient Greece and ancient Rome, archeological evidence suggests ''A. vulgaris'' was in cultivation by the 2nd c ...

Nectar Spur
A nectar spur is a hollow extension of a part of a flower. The spur may arise from various parts of the flower: the sepals, petals, or hypanthium, and often contain tissues that secrete nectar Nectar, (nectaries). Nectar spurs are present in many clades across the Flowering plant, angiosperms, and are often cited as an example of List of examples of convergent evolution, convergent evolution. Taxonomic significance Spur length can be an important diagnostic character for taxonomy, useful in species identification. For example, Yadon's piperia can be distinguished from ''Platanthera elegans'', an extremely similar species in section ''Piperia'' (Orchidaceae), by the unusually short length of its spur. Ecology and evolution The presence of nectar spurs in a clade of plants is associated with evolutionary processes such as coevolution (two-sided evolution) and pollinator shifts (one-sided evolution). Like variations in floral tube length, variation in nectar spur length has bee ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Sepal
A sepal () is a part of the flower of angiosperms (flowering plants). Usually green, sepals typically function as protection for the flower in bud, and often as support for the petals when in bloom., p. 106 Etymology The term ''sepalum'' was coined by Noël Martin Joseph de Necker in 1790, and derived . Collectively, the sepals are called the ''calyx'' (plural: calyces), the outermost Whorl (botany), whorl of parts that form a flower. The word ''calyx'' was adopted from the Latin ,Jackson, Benjamin, Daydon; A Glossary of Botanic Terms with their Derivation and Accent; Published by Gerald Duckworth & Co. London, 4th ed 1928 not to be confused with 'cup, goblet'. The Latin ''calyx'' is derived from Greek 'bud, calyx, husk, wrapping' ( Sanskrit 'bud'), while is derived from Greek 'cup, goblet'; both words have been used interchangeably in botanical Latin. Description The term ''tepal'' is usually applied when the parts of the perianth are difficult to distinguish, e. ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
