Iris Halophila
''Iris halophila'' is a species in the genus ''Iris'', it is also in the subgenus '' Limniris'' and in series '' Spuriae''. It is a rhizomatous perennial plant, with yellow, white or violet flowers. It is cultivated as an ornamental plant in temperate regions. It comes from a wide range from eastern Europe to China in Asia. It was known for a long while as a subspecies of ''Iris spuria'', before being treated as a separate species in its own right. Description It is similar in form to '' Iris orientalis'' but it is shorter. It has stout, thick, purple brown rhizomes, which can be 1.3–3 cm in diameter. Under the rhizome are thick roots. The rhizome spreads along the ground in a creeping habit. It has greyish-green, linear, erect, sword-shaped, leaves. That can grow up to long, and 0.7–2 cm wide. The leaves do not have a mid-vein. The leaves and foliage are sometimes longer than the flowering stems. Similar to ''Iris spuria'', they also have the ability to produce ...

Paul Friedrich August Ascherson
Paul Friedrich August Ascherson (June 4, 1834 – March 6, 1913) was a German botanist. His author citation is ''Asch.'', although ''Aschers.'' has been used in the past. Ascherson was born in Berlin in 1834 as the son of health counsellor. In 1850, he started studying medicine at the University of Berlin, but soon started getting more interested in botany. In 1855, he received his doctorate for a dissertation about the flora of the Margraviate of Brandenburg. In the 1850s, he started to botanize in Saxony, including several excursions with Ludwig Schneider and Gustav Maass. In 1860, Ascherson became an assistant at the Botanical Garden in Berlin; in 1865 he also started working at the Royal Herbarium. In 1863, he obtained his habilitation for specific botany and plant geography. In 1873, Ascherson became associate professor at the University of Berlin. He accompanied Friedrich Gerhard Rohlfs on his 1873/74 expedition in the Libyan desert. After 1876, he went on further expedit ...

Flavones
Flavones (from Latin ''flavus'' "yellow") are a class of flavonoids based on the backbone of 2-phenylchromen-4-one (2-phenyl-1-benzopyran-4-one) (as shown in the first image of this article). Flavones are common in foods, mainly from spices, and some yellow or orange fruits and vegetables. Common flavones include apigenin (4',5,7-trihydroxyflavone), luteolin (3',4',5,7-tetrahydroxyflavone), tangeritin (4',5,6,7,8-pentamethoxyflavone), chrysin (5,7-dihydroxyflavone), and 6-hydroxyflavone. Intake and elimination The estimated daily intake of flavones is about 2 mg per day. Following ingestion and metabolism, flavones, other polyphenols, and their metabolites are absorbed poorly in body organs and are rapidly excreted in the urine, indicating mechanisms influencing their presumed absence of metabolic roles in the body. Drug interactions Flavones have effects on CYP (P450) activity, which are enzymes that metabolize most drugs in the body. Biosynthesis The biosynthesis of f ...

Zygotic
A zygote (, ) is a eukaryotic cell formed by a fertilization event between two gametes. The zygote's genome is a combination of the DNA in each gamete, and contains all of the genetic information of a new individual organism. In multicellular organisms, the zygote is the earliest developmental stage. In humans and most other anisogamous organisms, a zygote is formed when an egg cell and sperm cell come together to create a new unique organism. In single-celled organisms, the zygote can divide asexually by mitosis to produce identical offspring. German zoologists Oscar and Richard Hertwig made some of the first discoveries on animal zygote formation in the late 19th century. Humans In human fertilization, a released ovum (a haploid secondary oocyte with replicate chromosome copies) and a haploid sperm cell (male gamete) combine to form a single diploid cell called the zygote. Once the single sperm fuses with the oocyte, the latter completes the division of the second ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Iris Pseudacorus
''Iris pseudacorus'', the yellow flag, yellow iris, or water flag, is a species of flowering plant in the family Iridaceae. It is native to Europe, western Asia and northwest Africa. Its specific epithet ''pseudacorus'' means "false acorus", referring to the similarity of its leaves to those of ''Acorus calamus'' (sweet flag), as they have a prominently veined mid-rib and sword-like shape. However, the two plants are not closely related. The flower is commonly attributed with the fleur-de-lis. Description This herbaceous flowering perennial plant grows to , or a rare tall, with erect leaves up to long and broad. The flowers are bright yellow, across, with the typical iris form. The fruit is a dry capsule long, containing numerous pale brown seeds. ''I. pseudacorus'' grows best in very wet conditions, and is common in wetlands, where it tolerates submersion, low pH, and anoxic soils. The plant spreads quickly, by both rhizome and water-dispersed seed. It fills a simila ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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 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 Phylogenetics, phylogenetic nor Morphology (biology), 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. ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Iris Laevigata
''Iris laevigata'', known as Japanese iris, rabbit-ear iris, or shallow-flowered iris (Japanese: カキツバタ), is a species of flowering plant in the family Iridaceae, native to Japan. It is related to other members of ''Iris'' subgenus '' Limniris'', including other species of Japanese irises.
