Iris Lortetii
''Iris lortetii'' (also known as Lortet's iris or in Israel as the Samarian iris) is a species in the genus ''Iris (plant), Iris''. It has straight grey-green leaves, a 30–50 cm tall stem, and large showy flowers in late spring or mid-summer that come in shades of pink, from white, lilac, pale lavender and grey-purple. It is veined and dotted pink or maroon. It has a signal patch that is deep maroon and a sparse and brown, purple-brown or reddish beard. Description ''Iris lortetii'' is thought to resemble various other irises such as ''Iris sari'', ''Iris gatesii'', and ''Iris susiana'',John Weathers and has been called ''perhaps the most beautiful Iris in the world''. It has a short, stout rhizome, that is brown and fibrous. They grow just under the surface of the soil and form little complex networks. It has grey-green leaves that are straight and sword-shaped. It can grow to between long, and wide. The leaves are larger than those of ''Iris susiana'', (an iris in t ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
William Barbey
William Barbey (1842–1914) was a Swiss botanist and politician. William Barbey was born on 14 July 1842 at Genthod in the canton of Geneva. He studied science at the Academy in Geneva and then engineering at the École Centrale de Paris. From 1862 to 1869, he worked in New York City. He married Caroline, the daughter of the prominent botanist Edmond Boissier. After his marriage, he studied botany and undertook botanical research in Spain, Palestine, Greece and Asia Minor. In 1885, he founded the publication ''Bulletin de l'Herbier Boissier'', which in 1910 became the ''Bulletin de la société botanique de Genève''. He built, largely at his own expense, the Yverdon–Saint-Croix railway. However, as a supporter of Sunday observance, he insisted that the trains did not run on that day.

Encyclopedia Of Life
The ''Encyclopedia of Life'' (''EOL'') is a free, online encyclopedia intended to document all of the 1.9 million living species known to science. It is compiled from existing trusted databases curated by experts and with the assistance of non-experts throughout the world. It aims to build one "infinitely expandable" page for each species, including video, sound, images, graphics, as well as text. In addition, the Encyclopedia incorporates content from the Biodiversity Heritage Library, which digitizes millions of pages of printed literature from the world's major natural history libraries. The project was initially backed by a US$50 million funding commitment, led by the MacArthur Foundation and the Sloan Foundation, who provided US$20 million and US$5 million, respectively. The additional US$25 million came from five cornerstone institutions—the Field Museum, Harvard University, the Marine Biological Laboratory, the Missouri Botanical Garden, and the Smithsonian Ins ...

Upper Galilee
The Upper Galilee ( he, הגליל העליון, ''HaGalil Ha'Elyon''; ar, الجليل الأعلى, ''Al Jaleel Al A'alaa'') is a geographical-political term in use since the end of the Second Temple period. It originally referred to a mountainous area straddling what today is northern Israel and southern Lebanon. The boundaries of this area were the Litani River in the north, the Mediterranean Sea in the west, the Lower Galilee in the south (from which it is separated by the Beit HaKerem Valley), and the upper Jordan River and the Hula Valley in the east. According to the 1st-century historian Josephus, the bounds of Upper Galilee stretched from Bersabe in the Beit HaKerem Valley to Baca (Peki'in) in the north. The extent of this region is approximately 470 km². However, in present-day Israeli usage, the toponym mainly refers only to the northern part of the Galilee that is under Israeli sovereignty. That is, the term today does not include the portion of Southern Le ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Egyptologist
Egyptology (from ''Egypt'' and Greek , '' -logia''; ar, علم المصريات) is the study of ancient Egyptian history, language, literature, religion, architecture and art from the 5th millennium BC until the end of its native religious practices in the 4th century AD. A practitioner of the discipline is an " Egyptologist". In Europe, particularly on the Continent, Egyptology is primarily regarded as being a philological discipline, while in North America it is often regarded as a branch of archaeology. History First explorers The earliest explorers of ancient Egypt were the ancient Egyptians themselves. Inspired by a dream he had, Thutmose IV led an excavation of the Great Sphinx of Giza and inscribed a description of the dream on the Dream Stele. Less than two centuries later, Prince Khaemweset, fourth son of Ramesses II, would gain fame for identifying and restoring historic buildings, tombs and temples, including pyramids; and has subsequently been described as ...

Louis Charles Émile Lortet
Louis Charles Émile Lortet (22 August 1836 – 26 December 1909) was a French physician, botanist, zoologist and Egyptologist who was a native of Oullins. He earned his medical doctorate in 1861, and his degree in natural sciences in 1867. He served as premier doyen at the Faculty of Medicine of Lyon from 1877 until 1906. Also, from 1868 to 1909, he was director of the natural history museum in Lyon. Lortet is remembered for his scientific and zoological expeditions to the Middle East ( Syria, Lebanon and Egypt). He performed studies of mummified animals from the New Kingdom of ancient Egypt, and in 1880 took part in an excavation of a Phoenician necropolis. Lortet was a member of numerous scientific societies, such as the ''Société de géographie de Lyon'', being a founding member in 1858. Species with the epithet of ''lorteti'' are named in his honor; an example being the pufferfish species ''Carinotetraodon lorteti''. Family His Grandmother Clémence Lortet (17 Septemb ...

Botanical Name
A botanical name is a formal scientific name conforming to the ''International Code of Nomenclature for algae, fungi, and plants'' (ICN) and, if it concerns a plant cultigen, the additional cultivar or Group epithets must conform to the '' International Code of Nomenclature for Cultivated Plants'' (ICNCP). The code of nomenclature covers "all organisms traditionally treated as algae, fungi, or plants, whether fossil or non-fossil, including blue-green algae ( Cyanobacteria), chytrids, oomycetes, slime moulds and photosynthetic protists with their taxonomically related non-photosynthetic groups (but excluding Microsporidia)." The purpose of a formal name is to have a single name that is accepted and used worldwide for a particular plant or plant group. For example, the botanical name '' Bellis perennis'' denotes a plant species which is native to most of the countries of Europe and the Middle East, where it has accumulated various names in many languages. Later, the plant w ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Chromosomes
A chromosome is a long DNA molecule with part or all of the genetic material of an organism. In most chromosomes the very long thin DNA fibers are coated with packaging proteins; in eukaryotic cells the most important of these proteins are the histones. These proteins, aided by chaperone proteins, bind to and condense the DNA molecule to maintain its integrity. These chromosomes display a complex three-dimensional structure, which plays a significant role in transcriptional regulation. Chromosomes are normally visible under a light microscope only during the metaphase of cell division (where all chromosomes are aligned in the center of the cell in their condensed form). Before this happens, each chromosome is duplicated (S phase), and both copies are joined by a centromere, resulting either in an X-shaped structure (pictured above), if the centromere is located equatorially, or a two-arm structure, if the centromere is located distally. The joined copies are now called s ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Diploid
Ploidy () is the number of complete sets of chromosomes in a cell, and hence the number of possible alleles for autosomal and pseudoautosomal genes. Sets of chromosomes refer to the number of maternal and paternal chromosome copies, respectively, in each homologous chromosome pair, which chromosomes naturally exist as. Somatic cells, tissues, and individual organisms can be described according to the number of sets of chromosomes present (the "ploidy level"): monoploid (1 set), diploid (2 sets), triploid (3 sets), tetraploid (4 sets), pentaploid (5 sets), hexaploid (6 sets), heptaploid or septaploid (7 sets), etc. The generic term polyploid is often used to describe cells with three or more chromosome sets. Virtually all sexually reproducing organisms are made up of somatic cells that are diploid or greater, but ploidy level may vary widely between different organisms, between different tissues within the same organism, and at different stages in an organism's life cycle. ...
