Iris Bloudowii
''Iris bloudowii'' is a species in the genus '' Iris'', it is also in the subgenus of '' Iris'' and in the ''Psammiris'' section. It is a rhizomatous perennial, from Russia, Siberia, Kazakhstan, Mongolia and China, with sickle-shaped leaves, slender stem and 2 bright or pale yellow flowers. It is cultivated as an ornamental plant in temperate regions. Description It is similar in form to '' Iris humilis'' (another Psammiris species). It has a thick, short, irregularly shaped, fibrous rhizome. They are in diameter. Under the rhizome, are numerous yellow-white, secondary roots. On top of the rhizome, are the brown, fibrous remains of old leaves.British Iris Society (1997) The rhizome has many branches, creating a slowly, creeping plant. It has 2–4, linear, or lanceolate, or sword-shaped basal leaves, They are slightly curved or sickle-shaped. They appear in spring, as broad, brown shoots, before turning greyish green, or light green, they can grow up to between long and 4 ...

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 undif ...

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 c ... [...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. ...

Iris Sanguinea
''Iris sanguinea'' is a rhizomatous flowering plant in the genus '' Iris'' and in the series '' Sibiricae''. It is cultivated as an ornamental plant in temperate regions. It is one of the species considered a Japanese iris. It is from Asia, found between Russia, Mongolia, China, Japan and Korea. It has grey green leaves, an unbranched flowering stem and flowers in reddish-purple shades, from blue to blue-purple, red-violet, with a rare white variant. A 2020 taxonomic revision suggests that previously distinguished taxa of ''Iris sanguinea'' and ''Iris sibirica'' bear no phylogenetic nor morphological distinction. As such, name ''I. sanguinea'' was synonymized with ''I. siberica''. Description It has a thick creeping rhizome. It has grey-green leaves that are more or less the same height as the flowering stems, but as the leaves droop, they appear shorter. The linear, narrow leaves grow between 20 and 60 cm long and 5–13 mm wide. It has a hollow unbranched flowe ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Iris Tenuifolia
''Iris tenuifolia'' 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 region over central Asia, including Afghanistan, Pakistan, (the former Soviet Union republics of); Kazakhstan, Uzbekistan and Mongolia and in China. It has long greyish-green leaves, short stem and pale violet, lilac, pale blue, or purple flowers. Description ''Iris tenuifolia'' is very similar in form to the Mediterranean ''Iris unguicularis''. As they both have very small stems and the seed capsules are often hidden within the leaves of the plant. It has a dark brown, thin, short, knobbly, tough, wood-like rhizomes. Underneath, it has a network of fibrous roots. On top of the rhizome, at the base of the leaves, are the brown or red-brown, fibrous remains of the previous seasons leaves.
