Acis Tingitana
''Acis tingitana'' is a species of flowering plant in the family Amaryllidaceae, native to north Morocco. Rare in cultivation, it is not fully frost-hardy. Description ''Acis tingitana'' is a bulbous flowering plant. Forms described under the synonym ''Leucojum fontianum'' have four to five leaves per bulb, each 6–8 mm wide, produced with the flowers in spring. The flowering stems are about 10–12 cm tall, and bear up to four flowers, with six 1–1.5 cm-long tepals, each with a sharply pointed tip. Forms described under the synonym ''Leucojum tingitanum'' are less robust, with narrower leaves. Taxonomy ''Acis tingitana'' was first described in 1878 by John Gilbert Baker, as ''Leucojum tingitanum''. The specific epithet ''tingitanus'' refers to Tangier, in Morocco. In 1934, René Maire described ''Leucojum fontianum''. Although in 1987 Brian Mathew regarded the two species as distinct, in 1992, he synonymized them. In 2004, ''Leucojum tingitanum'' was transfe ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Gothenburg Botanical Garden
The Gothenburg Botanical Garden ( sv, Göteborgs botaniska trädgård) is located in Gothenburg, Sweden, and is one of the larger botanical gardens in Europe. History The Gothenburg Botanical Garden is situated in a formerly completely rural area, where earlier a great country estate named Stora Änggården was located. The garden was initially funded by a donation from the Charles Felix Lindberg Foundation, in special memory of himself. Lindberg was a Swedish businessman and donor, who died in 1909. The Gothenburg City Council took the initiative to the botanical garden in 1912. The decision was finally taken in 1915 and work started in 1916. The park was opened to the public in 1919 (the Woodlands) and in 1923 (the cultivated areas). It was first planned as "a field for experimentation and biological demonstrations, and a nature park". Stora Änggården was built in 1812 and renovated under the supervision of the architect Sigfrid Ericson in 1919 and is now used as staff res ...

Flora Of Morocco
Morocco provides a refuge for a rich and diverse flora with about 4,200 taxa, of which 22% (879 taxa) are endemic. The phytogeographic zones of Morocco comprise 8 zones: the Mediterranean zone (central 0–500m, middle 500-1,000m and upper 1,100-1500m), the Cedar zone (1000-2000m), the sub-Alpine zone (2,000-2,500m), the Alpine zone (2,500m+), the semi-desert scrub zone, the Reg , the sandy desert zone and the oases. Mediterranean or coastal zone Maquis and Garrique Mediterranean dry woodlands and steppe, Mediterranean woodlands and forests, lower Northern slopes of Rif and Tell Atlas. The climax of the Mediterranean coast is a well-developed maquis commonly associated with ''Clematis'', ''Smilax'', ''Lonicera'' and ''Asparagus''. Except in inaccessible or protected places the vegetation has been heavily grazed by domestic animals and this degraded maquis, called garrigue, is widespread.

World Checklist Of Selected Plant Families
The World Checklist of Selected Plant Families (usually abbreviated to WCSP) is an "international collaborative programme that provides the latest peer reviewed and published opinions on the accepted scientific names and synonyms of selected plant families." Maintained by the Royal Botanic Gardens, Kew, it is available online, allowing searches for the names of families, genera and species, as well as the ability to create checklists. The project traces its history to work done in the 1990s by Kew researcher Rafaël Govaerts on a checklist of the genus ''Quercus''. Influenced by the Global Strategy for Plant Conservation, the project expanded. , 173 families of seed plants were included. Coverage of monocotyledon families is complete; other families are being added. There is a complementary project called the International Plant Names Index (IPNI), in which Kew is also involved. The IPNI aims to provide details of publication and does not aim to determine which are accepted spec ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
International Plant Names Index
The International Plant Names Index (IPNI) describes itself as "a database of the names and associated basic bibliographical details of seed plants, ferns and lycophytes." Coverage of plant names is best at the rank of species and genus. It includes basic bibliographical details associated with the names. Its goals include eliminating the need for repeated reference to primary sources for basic bibliographic information about plant names. The IPNI also maintains a list of standardized author abbreviations. These were initially based on Brummitt & Powell (1992), but new names and abbreviations are continually added. Description IPNI is the product of a collaboration between The Royal Botanic Gardens, Kew (Index Kewensis), The Harvard University Herbaria (Gray Herbarium Index), and the Australian National Herbarium ( APNI). The IPNI database is a collection of the names registered by the three cooperating institutions and they work towards standardizing the information. The stan ...

Molecular Phylogenetics
Molecular phylogenetics () is the branch of phylogeny that analyzes genetic, hereditary molecular differences, predominantly in DNA sequences, to gain information on an organism's evolutionary relationships. From these analyses, it is possible to determine the processes by which diversity among species has been achieved. The result of a molecular phylogenetic analysis is expressed in a phylogenetic tree. Molecular phylogenetics is one aspect of molecular systematics, a broader term that also includes the use of molecular data in taxonomy and biogeography. Molecular phylogenetics and molecular evolution correlate. Molecular evolution is the process of selective changes (mutations) at a molecular level (genes, proteins, etc.) throughout various branches in the tree of life (evolution). Molecular phylogenetics makes inferences of the evolutionary relationships that arise due to molecular evolution and results in the construction of a phylogenetic tree.

Leucojum
''Leucojum'' is a small genus of bulbous plants native to Eurasia belonging to the Amaryllis family, subfamily Amaryllidoideae. As currently circumscribed, the genus includes only two known species, most former species having been moved into the genus '' Acis''. Both genera are known as snowflakes. ''Leucojum'' is a compound of Greek λευκος, ''leukos'' "white" and ἰόν, ''ion'' "violet". The spelling ''Leucoium'' is also used. Other common names include snowbell, dewdrop, and St. Agnes' flower. Description Until 2004, the genus ''Leucojum'' was treated as including species now placed in ''Acis''. ''Leucojum'' when narrowly circumscribed consists of only two species, '' Leucojum aestivum'' and '' Leucojum vernum''. Compared to ''Acis'', ''Leucojum'' has hollow rather than solid flower stalks ( scapes), white flowers with green or yellow marks on both the inner and outer three tepals, flower stems (pedicels) at least as long as the spathes enclosing the inflorescence ...

Acis (plant)
''Acis '' is a genus of perennial, herbaceous and bulbous plants in the amaryllis family (Amaryllidaceae, subfamily Amaryllidoideae). The genus consists of nine species distributed in Europe and Northern Africa. ''Acis'' was previously included in '' Leucojum''; both genera are known as snowflakes. Description ''Acis'' species are perennial bulbous plants. The flowers have six equally sized tepals, unlike the related genus ''Galanthus'' (snowdrops) in which the inner three tepals are shorter than the outer three. The tepals are unmarked, differing in this respect from '' Leucojum''. Most species have white tepals, although those of '' Acis rosea'' are pale pink. ''Acis'' species are relatively short, up to in '' Acis autumnalis'' and in ''Acis tingitana''. The leaves are narrow; very narrow (filiform) in '' Acis trichophylla''. The flower stalks (scapes) are solid. Taxonomy ''Acis'' was first differentiated from the genus '' Leucojum'' by Richard Anthony Salisbury in ''The P ...

Tangier
Tangier ( ; ; ar, طنجة, Ṭanja) is a city in northwestern Morocco. It is on the Moroccan coast at the western entrance to the Strait of Gibraltar, where the Mediterranean Sea meets the Atlantic Ocean off Cape Spartel. The town is the capital of the Tanger-Tetouan-Al Hoceima region, as well as the Ṭanja-Aẓila Prefecture of Morocco. Many civilisations and cultures have influenced the history of Tangier, starting from before the 10th centuryBCE. Between the period of being a strategic Berber town and then a Phoenician trading centre to Morocco's independence era around the 1950s, Tangier was a nexus for many cultures. In 1923, it was considered as having international status by foreign colonial powers and became a destination for many European and American diplomats, spies, bohemians, writers and businessmen. The city is undergoing rapid development and modernisation. Projects include tourism projects along the bay, a modern business district called Tangier City Cent ...
