Ilex × Attenuata
''Ilex'' × ''attenuata'', the topal holly, is the result of a cross between '' Ilex cassine'' (dahoon) and '' Ilex opaca'' (American holly). It is a naturally occurring hybrid found in the southeastern United States where the ranges of the parents overlap, but hybrid cultivars have also been created. The best known cultivars are 'Fosteri', Foster holly, which does not require males to set fruit, and 'Savannah', with very showy red fruit. References attenuata ''Attenuata'' is a genus of minute sea snails, marine gastropod mollusks or micromollusks in the family Lironobidae.

William Willard Ashe
William Willard Ashe (June 4, 1872 – March 18, 1932) was an American forester and botanist. He was known as a prolific collector of plant specimens and an early proponent of conservationism in the Southern United States. Early life Ashe was born in Raleigh, North Carolina to Samuel A'Court Ashe (1840 – 1938) and Hannah Emerson Willard. He was the oldest of nine children and grew up on the family's antebellum estate "Elmwood," where he spent much of his childhood exploring the nearby woods and fields looking for natural curiosities. He quickly took to collecting plant specimens, and by the time he entered college, Ashe required a two-story building to house his entire collection. As a young man, Ashe also spent time writing; and along with his brother Samuel, he produced a tract titled "The West End Sun" that included woodcuts made by W.W. Ashe himself. A copy of "The West End Sun" was placed in the cornerstone of the State Agricultural College Building in Raleigh. [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Ilex Cassine
''Ilex cassine'' is a holly native to the southeastern coast of North America, in the United States from Virginia to southeast Texas, in Mexico in Veracruz, and in the Caribbean on the Bahamas, Cuba, and Puerto Rico. It is commonly known as dahoon holly or ''cassena'', the latter derived from the Timucua name for '' I. vomitoria''. It is a large shrub or small tree growing to 10–13 m tall. The leaves are evergreen, 6–15 cm long and 2–4 cm broad, glossy dark green, entire or with a few small spines near the apex of the leaf. The flowers are white, with a four-lobed corolla. The fruit is a red drupe, 5–6 mm in diameter, containing four seeds.Florida Department of Environmental ProtectionFlorida's HolliesHuxley, A., ed. (1992). ''New RHS Dictionary of Gardening''.

Ilex Opaca
''Ilex opaca'', the American holly, is a species of holly, native to the eastern and south-central United States, from coastal Massachusetts south to central Florida, and west to southeastern Missouri and eastern Texas. Description ''Ilex opaca'' is a medium-sized broadleaved evergreen tree growing on average to wide, and up to tall. Typically, its trunk diameter reaches , sometimes up to . The bark is light gray, roughened by small warty lumps. The branchlets are stout, green at first and covered with rusty down, later smooth and brown. The winter buds are brown, short, obtuse or acute. The leaves are alternate, long and wide, stiff, yellow green and dull matte to sub-shiny above (distinctly less glossy than the otherwise fairly similar European holly '' Ilex aquifolium''Huxley, A., ed. (1992). ''New RHS Dictionary of Gardening''. Macmillan .), often pale yellow beneath; the edges are curved into several sharp, spike-like points, and a wedge-shaped base and acute apex; ...

Hybrid (biology)
In biology, a hybrid is the offspring resulting from combining the qualities of two organisms of different breeds, varieties, species or genera through sexual reproduction. Hybrids are not always intermediates between their parents (such as in blending 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 hybridisation, which include genetic and morphological differences, differing times of fertility, mating behaviors and cues, and physiological rejection of sperm cells or the developing embryo. Some act before fertilization and others after it. Similar barriers exist in plants, with differences in floweri ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Cultivar
A cultivar is a type of cultivated plant that people have selected for desired traits and when propagated retain those traits. Methods used to propagate cultivars include: division, root and stem cuttings, offsets, grafting, tissue culture, or carefully controlled seed production. Most cultivars arise from purposeful human manipulation, but some originate from wild plants that have distinctive characteristics. Cultivar names are chosen according to rules of the International Code of Nomenclature for Cultivated Plants (ICNCP), and not all cultivated plants qualify as cultivars. Horticulturists generally believe the word ''cultivar''''Cultivar'' () has two meanings, as explained in '' Formal definition'': it is a classification category and a taxonomic unit within the category. When referring to a taxon, the word does not apply to an individual plant but to all plants that share the unique characteristics that define the cultivar. was coined as a term meaning "cultivated vari ...

Ilex
''Ilex'' (), or holly, is a genus of over 570 species of flowering plants in the family Aquifoliaceae, and the only living genus in that family. ''Ilex'' has the most species of any woody dioecious angiosperm genus. The species are evergreen or deciduous trees, shrubs, and climbers from tropics to temperate zones worldwide. The type species is ''Ilex aquifolium'', the common European holly used in Christmas decorations and cards. Description The genus ''Ilex'' is divided into three subgenera: *''Ilex'' subg. ''Byronia'', with the type species ''Ilex polypyrena'' *''Ilex'' subg. ''Prinos'', with 12 species *''Ilex'' subg. ''Ilex'', with the rest of the species The genus is widespread throughout the temperate and subtropical regions of the world. It includes species of trees, shrubs, and climbers, with evergreen or deciduous foliage and inconspicuous flowers. Its range was more extended in the Tertiary period and many species are adapted to laurel forest habitats. It occurs fr ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Interspecific Plant Hybrids
Biological specificity is the tendency of a characteristic such as a behavior or a biochemical variation to occur in a particular species. Biochemist Linus Pauling stated that "Biological specificity is the set of characteristics of living organisms or constituents of living organisms of being special or doing something special. Each animal or plant species is special. It differs in some way from all other species...biological specificity is the major problem about understanding life." Biological specificity within ''Homo sapiens'' ''Homo sapiens'' has many characteristics that show the biological specificity in the form of behavior and morphological traits. Morphologically, humans have an enlarged cranial capacity and more gracile features in comparison to other hominins. The reduction of dentition is a feature that allows for the advantage of adaptability in diet and survival. As a species, humans are culture dependent and much of human survival relies on the culture and soc ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Ornamental Trees
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 i ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
