Porteranthus
''Gillenia'' ( syn. ''Porteranthus'') is a genus of two species of perennial herbs in the family Rosaceae, '' Gillenia stipulata'' and '' Gillenia trifoliata''. Common names for plants in this genus include: Bowman's root, Indian-physic, American ipecac. This genus is endemic to dry open woods with acidic soils in eastern North America. Both plants are subshrubs with exposed semi-woody branches and serrated leaves; the larger lower leaves are divided into palmately arranged leaflets. Plants bloom in May, June, or July; blooms are composed of five slender white petals which are loosely arranged and typically appear slightly twisted and limp as if they were wilted. The flowers mature into small capsules. ''G. stipulata'' and ''G. trifoliata'' are often planted as ornamentals and used in herbal medicine. Classification and name Traditionally this genus is considered to be related to Spiraea, but it became apparent that it comes from the lineage which leads to tribe Maleae (which aro ...

Gillenia Trifoliata
''Gillenia trifoliata'', common name Bowman's root or Indian physic, is a species of flowering plant in the family (biology), family Rosaceae, native plant, native to eastern North America from Ontario to Georgia. It is an erect herbaceous plant, herbaceous perennial plant, perennial growing to tall by wide, with 3-palmate leaves and pale pink flowers with narrow petals and reddish sepal, calyces above red coloured stems in spring and summer. In cultivation, this plant has gained the Royal Horticultural Society's Award of Garden Merit. It is very hardiness (plants), hardy to or lower, but requires a sheltered position in partial shade, with acid soil, acid or neutral soil. The root was dried and powdered by Native Americans in the United States, Native Americans and used as both a laxative and emetic.

Conrad Moench
Conrad Moench (sometimes written Konrad Mönch; 15 August 1744 – 6 January 1805) was a German botanist, professor of botany at Marburg University from 1786 until his death. He wrote 'Methodus Plantas horti botanici et agri Marburgensis' in 1794, an arranged account of plants in the fields and gardens of Marburg. In 1802 he named the plant '' Gillenia trifoliata'' in a supplement to a local flora of the city of Marburg. He also named the plant genus ''Echinacea'' (1794). The botanical genus ''Moenchia'' (family Caryophyllaceae Caryophyllaceae, commonly called the pink family or carnation family, is a family of flowering plants. It is included in the dicotyledon order Caryophyllales in the APG III system, alongside 33 other families, including Amaranthaceae, Cactacea ...) is named in his honor. The standard botanical author abbreviation Moench is applied to plants he described. Principal writings * ''Enumeratio plantarum indigenarum Hassiae praesertim inferioris, sec ...

Phragmidium
''Phragmidium '' is a genus of rust fungus that typically infects plant species in the family Rosaceae. It is characterised by having stalked teliospores borne on telia each having a row of four or more cells. All species have a caeoma which is a diffuse aecidium lacking a peridium. There are a number of species of ''Phragmidium'', most of which are restricted to one or a few host species. Examples include: *'' Phragmidium acuminatum'' on '' Rubus saxatile'' *'' Phragmidium bulbosum'' on ''Rubus fruticosus'' and '' Rubeus caesius'' *'' Phragmidium mucronatum'' *'' Phragmidium sterilis'' on ''Potentilla sterilis'' *''Phragmidium potentillae'' on ''Potentilla anglica'' *''Phragmidium rosae-pimpinellifoliae'' *''Phragmidium rubi-idaei'' on raspberry *''Phragmidium tuberculatum'' on some rose cultivars *''Phragmidium violaceum'' on cultivated blackberry and loganberry Possibly the most commonly encountered is ''P. mucronatum'', found on most species of wild roses including ''Rosa c ...

Aneuploidy
Aneuploidy is the presence of an abnormal number of chromosomes in a cell, for example a human cell having 45 or 47 chromosomes instead of the usual 46. It does not include a difference of one or more complete sets of chromosomes. A cell with any number of complete chromosome sets is called a ''euploid'' cell. An extra or missing chromosome is a common cause of some genetic disorders. Some cancer cells also have abnormal numbers of chromosomes. About 68% of human solid tumors are aneuploid. Aneuploidy originates during cell division when the chromosomes do not separate properly between the two cells (nondisjunction). Most cases of aneuploidy in the autosomes result in miscarriage, and the most common extra autosomal chromosomes among live births are 21, 18 and 13. Chromosome abnormalities are detected in 1 of 160 live human births. Autosomal aneuploidy is more dangerous than sex chromosome aneuploidy, as autosomal aneuploidy is almost always lethal to embryos that cease develo ...

Chromosome Number
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.

Maleae
The Maleae (incorrectly Pyreae) are the apple tribe in the rose family, Rosaceae. The group includes a number of plants bearing commercially important fruits, such as apples and pears, while others are cultivated as ornamentals. Older taxonomies separated some of this group as tribe Crataegeae,G. K. Schulze-Menz 1964. ''Reihe Rosales''. in ''A. Engler's Syllabus der Pflanzenfamilien mit besonderer Berücksichtigung der Nutzpflanzen nebst einer Übersicht über die Florenreiche und Florengebiete der Erde'', Gebrüder Borntraeger, Berlin as the Cydonia group (a tentative placement), or some genera were placed in family Quillajaceae. The tribe consists exclusively of shrubs and small trees. Most have pomes, a type of accessory fruit that does not occur in other Rosaceae. All except ''Vauquelinia'' (with 15 chromosomes) have a basal haploid chromosome count of 17, instead of 7, 8, or 9 as in the other Rosaceae.

Herbal Medicine
Herbal medicine (also herbalism) is the study of pharmacognosy and the use of medicinal plants, which are a basis of traditional medicine. With worldwide research into pharmacology, some herbal medicines have been translated into modern remedies, such as the anti-malarial group of drugs called artemisinin isolated from ''Artemisia annua'', a herb that was known in Chinese medicine to treat fever. There is limited scientific evidence for the safety and efficacy of plants used in 21st century herbalism, which generally does not provide standards for purity or dosage. The scope of herbal medicine commonly includes fungal and bee products, as well as minerals, shells and certain animal parts. Herbal medicine is also called phytomedicine or phytotherapy. Paraherbalism describes alternative and pseudoscientific practices of using unrefined plant or animal extracts as unproven medicines or health-promoting agents. Paraherbalism relies on the belief that preserving various subst ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Ornamental Plant
Ornamental plants or garden plants are plants that are primarily grown for their beauty but also for qualities such as scent or how they shape physical space. Many flowering plants and garden varieties tend to be specially bred cultivars that improve on the original species in qualities such as color, shape, scent, and long-lasting blooms. There are many examples of fine ornamental plants that can provide height, privacy, and beauty for any garden. These ornamental perennial plants have seeds that allow them to reproduce. One of the beauties of ornamental grasses is that they are very versatile and low maintenance. Almost any types of plant have ornamental varieties: trees, shrubs, climbers, grasses, succulents. aquatic plants, herbaceous perennials and annual plants. Non-botanical classifications include houseplants, bedding plants, hedges, plants for cut flowers and foliage plants. The cultivation of ornamental plants comes under floriculture and tree nurseries, which is a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Wilting
Wilting is the loss of rigidity of non-woody parts of plants. This occurs when the turgor pressure in non-lignified plant cells falls towards zero, as a result of diminished water in the cells. Wilting also serves to reduce water loss, as it makes the leaves expose less surface area. The rate of loss of water from the plant is greater than the absorption of water in the plant. The process of wilting modifies the leaf angle distribution of the plant (or canopy) towards more erectophile conditions. Lower water availability may result from: * drought conditions, where the soil moisture drops below conditions most favorable for plant functioning; * the temperature falls to the point where the plant's vascular system cannot function; * high salinity, which causes water to diffuse from the plant cells and induce shrinkage; * saturated soil conditions, where roots are unable to obtain sufficient oxygen for cellular respiration, and so are unable to transport water into the plant; or ...
