Scadoxus Multiflorus (1)
''Scadoxus multiflorus'' (formerly ''Haemanthus multiflorus'') is a species of bulbous plant native to most of sub-Saharan Africa from Senegal to Somalia to South Africa. It is also native to Arabian Peninsula (Saudi Arabia, Yemen, Oman) and to the Seychelles. It is naturalized in Mexico and in the Chagos Archipelago.It is also found in Indian peninsula. It is grown as an ornamental plant for its brilliantly coloured flowers, either in containers or in the ground in where the climate is suitable. There are three recognized subspecies. Strongly toxic like other ''Scadoxus'' species, it has been used as a component of arrow poisons and fishing poisons, as well as in traditional medicine. Common names, some of which are used for other species, include blood lily, ball lily, fireball lily, blood flower, Katherine-wheel, oxtongue lily, poison root and powderpuff lily.

Pedicel (botany)
In botany, a pedicel is a stem that attaches a single flower to the inflorescence. Such inflorescences are described as ''pedicellate''. The stalk at the base of a leaf is called a petiole. Description Pedicel refers to a structure connecting a single flower to its inflorescence. In the absence of a pedicel, the flowers are described as sessile. Pedicel is also applied to the stem of the infructescence. The word "pedicel" is derived from the Latin ''pediculus'', meaning "little foot". The stem or branch from the main stem of the inflorescence that holds a group of pedicels is called a peduncle. A pedicel may be associated with a bract or bracts.

Synonym (taxonomy)
In taxonomy, the scientific classification of living organisms, a synonym is an alternative scientific name for the accepted scientific name of a taxon. The Botanical nomenclature, botanical and Zoological nomenclature, zoological codes of nomenclature treat the concept of synonymy differently. * In nomenclature, botanical nomenclature, a synonym is a Binomial nomenclature, scientific name that applies to a taxon that now goes by a different scientific name. For example, Carl Linnaeus, Linnaeus was the first to give a scientific name (under the currently used system of scientific nomenclature) to the Norway spruce, which he called ''Pinus abies''. This name is no longer in use, so it is now a synonym of the current scientific name, ''Picea abies''. * In zoology, moving a species from one genus to another results in a different Binomial nomenclature, binomen, but the name is considered an alternative combination rather than a synonym. The concept of synonymy in zoology is reserved f ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Chromosome
A chromosome is a package of DNA containing part or all of the genetic material of an organism. In most chromosomes, the very long thin DNA fibers are coated with nucleosome-forming packaging proteins; in eukaryotic cells, the most important of these proteins are the histones. Aided by chaperone proteins, the histones bind to and condense the DNA molecule to maintain its integrity. These eukaryotic chromosomes display a complex three-dimensional structure that has a significant role in transcriptional regulation. Normally, chromosomes are 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 stage occurs, each chromosome is duplicated ( S phase), and the two copies are joined by a centromere—resulting in either an X-shaped structure if the centromere is located equatorially, or a two-armed structure if the centromere is located distally; the jo ...

Scadoxus
''Scadoxus'' is a genus of African and Arabian plants in the Amaryllidaceae, Amaryllis family, subfamily Amaryllidoideae. The English names blood lily or blood flower are used for some of the species. The genus has close affinities with ''Haemanthus.'' Species of ''Scadoxus'' are grown as ornamental plants for their brilliantly coloured flowers, either in containers or in the ground in frost-free climates. Although some species have been used in traditional medicine, they contain poisonous alkaloids. Description Species of ''Scadoxus'' grow from bulbs or rhizomes. Bulbous species usually also have distinct rhizomes. Particularly in the non-bulbous species, the petiole (botany), petioles (leaf stalks) overlap to produce a false stem or pseudostem, which may be purple-spotted. The leaf blades are lanceolate to ovate with a thickened midrib. The leafless flowering stem (Scape (botany), scape) is also sometimes purple-spotted, and either appears from among the leaves or pushes thro ...

Species Description
A species description is a formal scientific description of a newly encountered species, typically articulated through a scientific publication. Its purpose is to provide a clear description of a new species of organism and explain how it differs from species that have been previously described or related species. For a species to be considered valid, a species description must follow established guidelines and naming conventions dictated by relevant nomenclature codes. These include the International Code of Zoological Nomenclature (ICZN) for animals, the International Code of Nomenclature for algae, fungi, and plants (ICN) for plants, and the International Committee on Taxonomy of Viruses (ICTV) for viruses. A species description often includes photographs or other illustrations of type material and information regarding where this material is deposited. The publication in which the species is described gives the new species a formal scientific name. Some 1.9 million ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Berry (botany)
In botany, a berry is a fleshy fruit without a drupe, drupe (pit) produced from a single flower containing one Ovary (botany), ovary. Berries so defined include grapes, Ribes, currants, and tomatoes, as well as cucumbers, eggplants (aubergines), persimmons and bananas, but exclude certain fruits that meet the berry, culinary definition of berries, such as strawberries and raspberries. The berry is the most common type of fleshy fruit in which the entire outer layer of the ovary wall ripens into a potentially edible "pericarp". Berries may be formed from one or more gynoecium, carpels from the same flower (i.e. from a simple or a compound ovary). The seeds are usually embedded in the fleshy interior of the ovary, but there are some non-fleshy exceptions, such as ''Capsicum'' species, with air rather than pulp around their seeds. Many berries are edible, but others, such as the Potato fruit, fruits of the potato and the deadly nightshade, are poisonous to humans. A plant that be ...
