Iris Spuria Subsp. Carthaliniae
''Iris spuria'' subsp. ''carthaliniae'' is a species in the genus '' Iris''. It is also in the subgenus of '' Limniris'' and in the series '' Spuriae''. It is a subspecies of ''Iris spuria'', a rhizomatous perennial plant, from the Caucasus region, it is a tall iris with sky blue or white flowers. It was originally described by Fomin, as a separate species before Brian Mathew in 1981, added it to ''Iris spuria'' as one of its many subspecies. It is cultivated as an ornamental plant in temperate regions. Description It has a thick, creeping, horizontal, branched rhizome. The creeping habit creates large clumps of plants. It has linear, flat, lanceolate, acuminate (ending in a point), leaves. These can grow up to between long and 10–18 mm wide. The leaves are generally either equal to the flowering stem or longer than it.British Iris Society (1997) James Cullen, Sabina G. Knees, H. Suzanne Cubey (Editors) It has a sightly compressed, stem (or peduncle), that grows up ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Aleksandr Fomin (botanist)
Aleksandr Vasiljevich Fomin was a Russian botanist that lived during the reign of the Soviet Union. He studied ferns and seed plants. He was also a director of the Kiev University Botanical Garden; which was renamed after him, when he died. Biography He was born in the village of Ermolevka in Petrovsk, Saratov Oblast on (. From 1888 to 1890, Fomin along with Nicolaĭ Adolfowitsch Busch and Nikolai Ivanovich Kuznetsov, funded by the Russian Geographical Society, took several botanical and geographical expeditions to the Caucasus. In 1893, he graduated from Moscow University. In 1896, he became a graduate assistant at the Universität Dorpat (now known as the University of Tartu, Estonia). Foin, Busch and Kuznetsov later wrote 'Flora Caucasica critica' (Materially dlia flory Kavkaza : kriticheskoe sistematichesko-geograficheskoe izsliedovanie), which was published between 1901 and 1913.

Tepals
A tepal is one of the outer parts of a flower (collectively the perianth). The term is used when these parts cannot easily be classified as either sepals or petals. This may be because the parts of the perianth are undifferentiated (i.e. of very similar appearance), as in ''Magnolia'', or because, although it is possible to distinguish an outer whorl of sepals from an inner whorl of petals, the sepals and petals have similar appearance to one another (as in ''Lilium''). The term was first proposed by Augustin Pyramus de Candolle in 1827 and was constructed by analogy with the terms "petal" and "sepal". (De Candolle used the term ''perigonium'' or ''perigone'' for the tepals collectively; today, this term is used as a synonym for ''perianth''.) p. 39. Origin Undifferentiated tepals are believed to be the ancestral condition in flowering plants. For example, '' Amborella'', which is thought to have separated earliest in the evolution of flowering plants, has flowers with undiffer ...

Georgia (country)
Georgia (, ; ) is a transcontinental country at the intersection of Eastern Europe and Western Asia. It is part of the Caucasus region, bounded by the Black Sea to the west, by Russia to the north and northeast, by Turkey to the southwest, by Armenia to the south, and by Azerbaijan to the southeast. The country covers an area of , and has a population of 3.7 million people. Tbilisi is its capital as well as its largest city, home to roughly a third of the Georgian population. During the classical era, several independent kingdoms became established in what is now Georgia, such as Colchis and Iberia. In the early 4th century, ethnic Georgians officially adopted Christianity, which contributed to the spiritual and political unification of the early Georgian states. In the Middle Ages, the unified Kingdom of Georgia emerged and reached its Golden Age during the reign of King David IV and Queen Tamar in the 12th and early 13th centuries. Thereafter, the kingdom decl ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Kartli
Kartli ( ka, ქართლი ) is a historical region in central-to-eastern Georgia traversed by the river Mtkvari (Kura), on which Georgia's capital, Tbilisi, is situated. Known to the Classical authors as Iberia, Kartli played a crucial role in the ethnic and political consolidation of the Georgians in the Middle Ages. Kartli had no strictly defined boundaries and they significantly fluctuated in the course of history. After the partition of the kingdom of Georgia in the 15th century, Kartli became a separate kingdom with its capital at Tbilisi. The historical lands of Kartli are currently divided among several administrative regions of Georgia. The Georgians living in the historical lands of Kartli are known as Kartleli (ქართლელი) and comprise one of the largest geographic subgroups of the Georgian people. Most of them are Eastern Orthodox Christians adhering to the national Georgian Orthodox Church and speak a dialect which is the basis of the modern Georg ...

The scented red flowers have numerous yellow stamens in the centre. Description ''Paeonia tenuifolia'' is a hairless herbaceous perennial plant with a stem of 30–60 cm high, which is densely set with alternately arranged compound leaves. The lowest leaves are twice compounded or the leaflets are deeply divided into many fine linear segments, ½-6 mm wide, with a blunt to rounded tip, dark green above, and lighter glaucous green below. The usually single flower on each stem seems to be floating on the foliage. ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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 was intro ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Pinyin
Hanyu Pinyin (), often shortened to just pinyin, is the official romanization system for Standard Mandarin Chinese in China, and to some extent, in Singapore and Malaysia. It is often used to teach Mandarin, normally written in Chinese form, to learners already familiar with the Latin alphabet. The system includes four diacritics denoting tones, but pinyin without tone marks is used to spell Chinese names and words in languages written in the Latin script, and is also used in certain computer input methods to enter Chinese characters. The word ' () literally means "Han language" (i.e. Chinese language), while ' () means "spelled sounds". The pinyin system was developed in the 1950s by a group of Chinese linguists including Zhou Youguang and was based on earlier forms of romanizations of Chinese. It was published by the Chinese Government in 1958 and revised several times. The International Organization for Standardization (ISO) adopted pinyin as an international standard ...

Chinese Characters
Chinese characters () are logograms developed for the writing of Chinese. In addition, they have been adapted to write other East Asian languages, and remain a key component of the Japanese writing system where they are known as ''kanji''. Chinese characters in South Korea, which are known as ''hanja'', retain significant use in Korean academia to study its documents, history, literature and records. Vietnam once used the '' chữ Hán'' and developed chữ Nôm to write Vietnamese before turning to a romanized alphabet. Chinese characters are the oldest continuously used system of writing in the world. By virtue of their widespread current use throughout East Asia and Southeast Asia, as well as their profound historic use throughout the Sinosphere, Chinese characters are among the most widely adopted writing systems in the world by number of users. The total number of Chinese characters ever to appear in a dictionary is in the tens of thousands, though most are graphic ...

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 sis ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
