Berberis Coloradensis
''Berberis'' (), commonly known as barberry, is a large genus of deciduous and evergreen shrubs from tall, found throughout temperate and subtropical regions of the world (apart from Australia). Species diversity is greatest in South America and Asia; Europe, Africa and North America have native species as well. The best-known ''Berberis'' species is the European barberry, ''Berberis vulgaris'', which is common in Europe, North Africa, the Middle East, and central Asia, and has been widely introduced in North America. Many of the species have spines on the shoots and all along the margins of the leaves. Description The genus ''Berberis'' has dimorphic shoots: long shoots which form the structure of the plant, and short shoots only long. The leaves on long shoots are non-photosynthetic, developed into one to three or more spines long. The bud in the axil of each thorn-leaf then develops a short shoot with several normal, photosynthetic leaves. These leaves are long, simple, ...

Mahonia Hakeaefolia
''Mahonia'' is a formerly accepted genus of approximately 70 species of shrubs or, rarely, small trees with evergreen leaves in the family Berberidaceae, native to eastern Asia, the Himalaya, North America, and Central America. They are closely related to the genus ''Berberis'' and as of 2023 the majority of botanical sources list it as a synonym for ''Berberis.'' However, there is still disagreement among botanists, and as recently as 2017 papers have been published arguing for the validity of the genus. In addition, sources that are updated less frequently like the USDA Natural Resources Conservation Service PLANTS database have many plants listed in ''Mahonia''. Most botanists prefer to classify ''Mahonia'' as a part of ''Berberis'' because several species in both genera are able to hybridize, and because there are no consistent morphological differences between the two groups other than the leaf pinnation (''Berberis sensu stricto'' appear to have simple leaves, but these a ...

Vaccinium Creedensis
''Vaccinium'' is a common and widespread genus of shrubs or dwarf shrubs in the heath family (Ericaceae). The fruits of many species are eaten by humans and some are of commercial importance, including the cranberry, blueberry, bilberry (whortleberry), lingonberry (cowberry), and huckleberry. Like many other heath plants, they are restricted to acidic soils. Description The plant structure varies between species: some trail along the ground, some are dwarf shrubs, and some are larger shrubs perhaps tall. Some tropical species are epiphytic. Stems are usually woody. Flowers are epigynous with fused petals and have long styles that protrude from their bell-shaped corollas. Stamens have anthers with extended tube-like structures called "awns" through which pollen falls when mature. Inflorescences can be axillary or terminal. The fruit develops from an inferior ovary and is a four- or five-parted berry; it is usually brightly coloured, often red or bluish with purple juice. Root ...

Philadelphus Creedensis
''Philadelphus'' () (mock-orange) is a genus of about 60 species of shrubs from 3–20 ft (1–6 m) tall, native to North America, Central America, Asia and (locally) in southeast Europe. They are named "mock-orange" in reference to their flowers, which in wild species look somewhat similar to those of oranges and lemons (''Citrus'') at first glance, and smell of orange flowers and jasmine (''Jasminum''). But ''Philadelphus'' is a basal asterid, not closely related to ''Jasminum'' (advanced asterids), and among the eudicots quite distant from ''Citrus'' (advanced rosids). An entirely misleading name for ''Philadelphus'' that is sometimes encountered is ''syringa''; this properly refers to the lilacs, which are fairly close relatives of jasmine. The connection of the two shrubs lies in their introduction from Ottoman gardens to European ones, effected at the same time by the Holy Roman emperor's ambassador to the Sublime Porte, Ogier Ghiselin de Busbecq, who returned to Vi ...

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] |
