Iris Loczyi
''Iris loczyi'' is a beardless iris in the genus ''Iris'', in the subgenus '' Limniris'' and in the series '' Tenuifoliae'' of the genus. It is a rhizomatous herbaceous perennial, from a wide area of Asia, including Afghanistan, Iran (the mountainous parts of Pakistan), Kazakhstan, Tajikistan, Mongolia, Tibet and China. It has long thin grey green leaves, long stems and 1 flower in pale violet, blue violet, lavender or light blue. Description It was once thought to be a form of ''Iris tenuifolia'', especially in China. It has a slender, fibrous, knobbly or gnarled, brown-black rhizome. It forms hard thick, tussocks or clumps of plants. On top of the rhizome are maroon-brown, fibrous (or straw-like), remnants (of last seasons leaves), as sheaths (of the new leaves). It has long and thin, linear, green-grey leaves, measuring long and 2-5mm wide. The leaves are sometimes evergreen. It has flower stems, that are long. They are sometimes only just above the ground level. It has 3 ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
August Kanitz
August Kanitz (25 April 1843, in Lugos – 12 July 1896, in Kolozsvár) was a Hungarian botanist. While a student at the University of Vienna he wrote ''Geschichte der Botanik in Ungarn'' (Hanover and Budapest, 1863), and soon after, ''Versuch einer Geschichte der Ungarischen Botanik'' (Halle, 1865). In 1866 he published a work on the flora of Slavonia, in 1877 he published a work on the flora of Montenegro, Bosnia, and Serbia and in 1879 one on that of Romania. For the last-named work he was elected (1880) a member of the Hungarian Academy of Sciences, and was made Knight of the Order of the Crown of Romania. He converted to Christianity. In 1872 Kanitz was appointed professor of botany at the Franz Joseph University. In 1877 he founded the ''Magyar Növénytani Lapok'' ('' Hungarian Journal of Botany''), which he edited until 1892.

Spathe
In botany, a bract is a modified or specialized leaf, especially one associated with a reproductive structure such as a flower, inflorescence axis or cone scale. Bracts are usually different from foliage leaves. They may be smaller, larger, or of a different color, shape, or texture. Typically, they also look different from the parts of the flower, such as the petals or sepals. A plant having bracts is referred to as bracteate or bracteolate, while one that lacks them is referred to as ebracteate and ebracteolate, without bracts. Variants Some bracts are brightly-coloured and serve the function of attracting pollinators, either together with the perianth or instead of it. Examples of this type of bract include those of ''Euphorbia pulcherrima'' (poinsettia) and ''Bougainvillea'': both of these have large colourful bracts surrounding much smaller, less colourful flowers. In grasses, each floret (flower) is enclosed in a pair of papery bracts, called the lemma (lower bract) and pa ... [...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] |
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 ...

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] |
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.
