Zephyranthes Nivea
''Zephyranthes'' is a genus of temperate and tropical bulbous plants in the Amaryllis family, subfamily Amaryllidoideae, native to the Americas and widely cultivated as ornamentals. Following the expansion of the genus in 2019, which now includes the genera ''Habranthus'' and ''Sprekelia'', there are about 200 recognized species, as well as numerous hybrids and cultivars. Common names for species in this genus include fairy lily, rainflower, zephyr lily, magic lily, Atamasco lily, and rain lily. The name is derived from Ζέφυρος (''Zephyrus''), the Greek god of the west wind, and ἄνθος (''anthos''), meaning flower, referring to the slender stalks. Description Species in the genus vary in morphology. Along with floral morphology, characteristics such as bulb size, bulb tunic color, and leaf morphology help identify individual species. Foliage in the wild is often ephemeral, but under cultivation becomes more persistent. Leaf color ranges from the bright gr ...

Zephyranthes Candida
''Zephyranthes candida'', with common names that include autumn zephyrlily, white windflower, white rain lily, and Peruvian swamp lily, is a species of Zephyranthes, rain lily native to South America including Argentina, Uruguay, Paraguay, and Brazil. The species is widely cultivated as an ornamental and reportedly naturalized in many places (South Africa, the Indian subcontinent, Zimbabwe, Seychelles, central and southern China, Korea, Nansei-shoto (Ryukyu Islands), Bhutan, Solomon Islands, Queensland, Nauru, Tonga, Society Islands, Mariana Islands, southeastern United States (from Texas to North Carolina), the Lesser Antilles, and Peru). Description Leaves are a deep glossy green and measure 3 Millimetre, mm wide. Flowers, which bud late in August (when propagated in the Northern Hemisphere) at first resemble a new leaf, but emerge from their papery sheaves to a stunning whiteness; they are erect in perianth white and sometimes pinkish abaxially. The leaf-like bract is 1. ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Hybrid (biology)
In biology, a hybrid is the offspring resulting from combining the qualities of two organisms of different varieties, subspecies, species or genera through sexual reproduction. Generally, it means that each cell has genetic material from two different organisms, whereas an individual where some cells are derived from a different organism is called a chimera. Hybrids are not always intermediates between their parents such as in blending inheritance (a now discredited theory in modern genetics by particulate inheritance), but can show hybrid vigor, sometimes growing larger or taller than either parent. The concept of a hybrid is interpreted differently in animal and plant breeding, where there is interest in the individual parentage. In genetics, attention is focused on the numbers of chromosomes. In taxonomy, a key question is how closely related the parent species are. Species are reproductively isolated by strong barriers to hybridization, which include genetic and morph ...

Type (biology)
In biology, a type is a particular specimen (or in some cases a group of specimens) of an organism to which the scientific name of that organism is formally associated. In other words, a type is an example that serves to anchor or centralizes the defining features of that particular taxon. In older usage (pre-1900 in botany), a type was a taxon rather than a specimen. A taxon is a scientifically named grouping of organisms with other like organisms, a set that includes some organisms and excludes others, based on a detailed published description (for example a species description) and on the provision of type material, which is usually available to scientists for examination in a major museum research collection, or similar institution. Type specimen According to a precise set of rules laid down in the International Code of Zoological Nomenclature (ICZN) and the ''International Code of Nomenclature for algae, fungi, and plants'' (ICN), the scientific name of every taxon is ...

Apomictic
In botany, apomixis is asexual reproduction, asexual development of seed or embryo without Fertilisation, fertilization. However, other definitions include replacement of the seed by a plantlet or replacement of the flower by bulbils. Apomictically produced offspring are genetically identical to the parent plant, except in nonrecurrent apomixis. Its etymology is Greek for "away from" + "mixing". Normal asexual reproduction of plants, such as propagation from Cutting (plant), cuttings or leaves, has never been considered to be apomixis. In contrast to parthenocarpy, which involves seedless fruit formation without fertilization, apomictic fruits have viable seeds containing a proper embryo, with asexual origin. In flowering plants, the term "apomixis" is used in a restricted sense to mean agamospermy, i.e. cloning, clonal reproduction through seeds. Although agamospermy could theoretically occur in gymnosperms, it appears to be absent in that group. Apogamy is a related term ...

Common Name
In biology, a common name of a taxon or organism (also known as a vernacular name, English name, colloquial name, country name, popular name, or farmer's name) is a name that is based on the normal language of everyday life; and is often contrasted with the scientific name for the same organism, which is often based in Latin. A common name is sometimes frequently used, but that is not always the case. In chemistry, IUPAC defines a common name as one that, although it unambiguously defines a chemical, does not follow the current systematic naming convention, such as acetone, systematically 2-propanone, while a vernacular name describes one used in a lab, trade or industry that does not unambiguously describe a single chemical, such as copper sulfate, which may refer to either copper(I) sulfate or copper(II) sulfate. Sometimes common names are created by authorities on one particular subject, in an attempt to make it possible for members of the general public (including s ...
