Blackberry
The blackberry is an edible fruit produced by many species in the genus ''Rubus'' in the family Rosaceae, hybrids among these species within the subgenus ''Rubus'', and hybrids between the subgenera ''Rubus'' and ''Idaeobatus''. The taxonomy of blackberries has historically been confused because of hybridization and apomixis, so that species have often been grouped together and called species aggregates. For example, the entire subgenus ''Rubus'' has been called the '' Rubus fruticosus'' aggregate, although the species ''R. fruticosus'' is considered a synonym of '' R. plicatus''. '' Rubus armeniacus'' ("Himalayan" blackberry) is considered a noxious weed and invasive species in many regions of the Pacific Northwest of Canada and the United States, where it grows out of control in urban and suburban parks and woodlands. Description What distinguishes the blackberry from its raspberry relatives is whether or not the torus ( receptacle or stem) "picks with" (i.e., stays w ...

Rubus Ursinus
''Rubus ursinus'' is a North American species of blackberry or dewberry, known by the common names California blackberry, California dewberry, Douglas berry, Pacific blackberry, Pacific dewberry and trailing blackberry. Description ''Rubus ursinus'' is a wide, mounding shrub or vine, growing to high, and more than wide. The prickly branches can take root if they touch soil, thus enabling the plant to spread vegetatively and form larger clonal colonies. The leaves usually have 3 leaflets but sometimes 5 or only 1, and are deciduous. The plant is dioecious, with male and female plants on separate plants, also unusual for the genus. As with other ''Rubus'', the canes are typically vegetative the first year, and reproductive in the second. The flowers are white with narrower petals than most related species, and have a fragrance. The sweet, very aromatic, edible fruits are dark purple, dark red, or black and up to in length. Taxonomy Subspecies and varieties Current o ...

Rubus Armeniacus
''Rubus armeniacus'', the Himalayan blackberry or Armenian blackberry, is a species of ''Rubus'' in the blackberry group ''Rubus'' subgenus ''Rubus'' series ''Discolores'' (P.J. Müll.) Focke. It is native to Armenia and Northern Iran, and widely naturalised elsewhere. Both its scientific name and origin have been the subject of much confusion, with much of the literature referring to it as either ''Rubus procerus'' or ''Rubus discolor'', and often mistakenly citing its origin as western European.Ceska, A. (1999). ''Rubus armeniacus'' - a correct name for Himalayan Blackberries ''Botanical Electronic News'' 230. AvailablonlineFlora of NW Europe''Rubus armeniacus''/ref> Flora of North America, published in 2014, considers the taxonomy unsettled, and tentatively uses the older name '' Rubus bifrons''. In some areas, the plant is cultivated for its berries, but in many areas it is considered a noxious weed and an invasive species. Description ''Rubus armeniacus'' is a perennial pl ...

Rubus
''Rubus'' is a large and diverse genus of flowering plants in the rose family, Rosaceae, subfamily Rosoideae, with over 1,350 species. Raspberries, blackberries, and dewberries are common, widely distributed members of the genus. Most of these plants have woody stems with prickles like roses; spines, bristles, and gland-tipped hairs are also common in the genus. The ''Rubus'' fruit, sometimes called a bramble fruit, is an aggregate of drupelets. The term "cane fruit" or "cane berry" applies to any ''Rubus'' species or hybrid which is commonly grown with supports such as wires or canes, including raspberries, blackberries, and hybrids such as loganberry, boysenberry, marionberry and tayberry. The stems of such plants are also referred to as canes. Description Most species in the genus are hermaphrodites, '' Rubus chamaemorus'' being an exception. ''Rubus'' species have a basic chromosome number of seven. Polyploidy from the diploid (14 chromosomes) to the tetradecaplo ...

Bramble
A bramble is any rough, tangled, prickly shrub, usually in the genus ''Rubus'', which grows blackberries, raspberries, or dewberries. "Bramble" is also used to describe other prickly shrubs, such as roses (''Rosa'' species). The fruits include blackberries, arctic brambleberries, or raspberries, depending on the species, and are used to make jellies, jams, and preserves. In British English, bramble usually refers to the common blackberry, ''Rubus fruticosus''. ''R. fruticosus'' grows abundantly in all parts of the British Isles, and harvesting the fruits in late summer and autumn is often considered a favourite pastime. An especially hardy plant, bramble bushes can also become a nuisance in gardens, sending down strong suckering roots amongst hedges and shrubs and being particularly resilient against pruning. Many consider ''R. fruticosus'' a weed due its tendency to grow in neglected areas and its sharp, tough thorns, which can be hazardous to children and pets. ...

Rubus Allegheniensis
''Rubus allegheniensis'' is a North American species of glandular highbush blackberry in section Alleghenienses of the genus ''Rubus'', a member of the rose family. It is the most common and widespread highbush blackberry in eastern and central North America. It is commonly known as Allegheny blackberry. Description The characteristics of ''Rubus allegheniensis'' can be highly variable. It is an erect bramble, typically but occasionally rarely over high, with single shrubs approaching 2.4 m or more in breadth, although it usually forms dense thickets of many plants. The leaves are alternate, compound, ovoid, and have toothed edges. Canes have many prickles, with white, 5-petal, flowers in late spring and glossy, deep-violet to black, aggregate fruit in late summer. It is shade intolerant.Peterson, Chris J., and Steward T.A.

Raspberry
The raspberry is the edible fruit of a multitude of plant species in the genus ''Rubus'' of the rose family, most of which are in the subgenus '' Idaeobatus''. The name also applies to these plants themselves. Raspberries are perennial with woody stems. World production of raspberries in 2020 was 895,771 tonnes, led by Russia with 20% of the total. Description A raspberry is an aggregate fruit, developing from the numerous distinct carpels of a single flower. What distinguishes the raspberry from its blackberry relatives is whether or not the torus ( receptacle or stem) "picks with" (i.e., stays with) the fruit. When picking a blackberry fruit, the torus stays with the fruit. With a raspberry, the torus remains on the plant, leaving a hollow core in the raspberry fruit. Raspberries are grown for the fresh fruit market and for commercial processing into individually quick frozen (IQF) fruit, purée, juice, or as dried fruit used in a variety of grocery products such as ras ...

Rubus Argutus
''Rubus argutus'' is a North American species of prickly bramble in the rose family. It is a perennial plant native to the eastern and south-central United States. Common names are sawtooth blackberry or tall blackberry after its high growth. Description ''R. argutus'' usually forms woody shrubs or vines, up to 2 meters (80 inches) in height,Rydberg, Per Axel (1901''Rubus argutus''in Britton, Nathaniel, ''Manual of the Flora of the northern States and Canada''. p. 498. with thorns on stems, leaves, and flowers. The leaves are alternate and palmately compound. First-year plants have palmate leaves with 5 leaflets while second-year plants have palmate leaves with 3 leaflets. Second-year plants develop racemes of flowers each containing 5–20 flowers. The flowers are typically 5-merous with large, white petals and light green sepals, borne in mid-spring. Second-year plants are also capable of growing the fruit which gives the plant's common name, the blackberry. The fruits are ...

Fruit
In botany, a fruit is the seed-bearing structure in flowering plants that is formed from the ovary after flowering. Fruits are the means by which flowering plants (also known as angiosperms) disseminate their seeds. Edible fruits in particular have long propagated using the movements of humans and animals in a symbiotic relationship that is the means for seed dispersal for the one group and nutrition for the other; in fact, humans and many animals have become dependent on fruits as a source of food. Consequently, fruits account for a substantial fraction of the world's agricultural output, and some (such as the apple and the pomegranate) have acquired extensive cultural and symbolic meanings. In common language usage, "fruit" normally means the seed-associated fleshy structures (or produce) of plants that typically are sweet or sour and edible in the raw state, such as apples, bananas, grapes, lemons, oranges, and strawberries. In botanical usage, the term "fruit" ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Rubus Laciniatus
''Rubus laciniatus'', the cutleaf evergreen blackberry or evergreen blackberry, is a species of ''Rubus'', native to Eurasia. It is an introduced species in Australia and North America. It has become a weed and invasive species in forested habitats in the United States and Canada, particularly in the Northeast and along the Pacific Coast. Description ''Rubus laciniatus'' is a deciduous, bramble-forming shrub growing to 3 meters (10 feet) tall, with prickly shoots. The leaves are palmately compound, with five leaflets, each divided into deeply toothed subleaflets with jagged, thorny tips. The flowers have pink or white petals. Fruits are similar to the common blackberry, with a unique, fruitier flavour. [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Rubus Fruticosus
''Rubus fruticosus'' L. is the ambiguous name of a European blackberry species in the genus ''Rubus'' in the rose family. The name has been interpreted in several ways: *The species represented by the type specimen of ''Rubus fruticosus'' L., which is also the type specimen of the genus ''Rubus''. This specimen is considered to match the species '' R. plicatus'', in ''Rubus'' subgenus ''Rubus'', section ''Rubus''. * Various species consistent with Linnaeus' original description of the species, which was based on a mixture of specimens now considered to match '' Rubus ulmifolius'' and ''R. plicatus'' *a species aggregate (group of similar species) ''Rubus fruticosus'' agg.

Species
In biology, a species is the basic unit of classification and a taxonomic rank of an organism, as well as a unit of biodiversity. A species is often defined as the largest group of organisms in which any two individuals of the appropriate sexes or mating types can produce fertile offspring, typically by sexual reproduction. Other ways of defining species include their karyotype, DNA sequence, morphology, behaviour or ecological niche. In addition, paleontologists use the concept of the chronospecies since fossil reproduction cannot be examined. The most recent rigorous estimate for the total number of species of eukaryotes is between 8 and 8.7 million. However, only about 14% of these had been described by 2011. All species (except viruses) are given a two-part name, a "binomial". The first part of a binomial is the genus to which the species belongs. The second part is called the specific name or the specific epithet (in botanical nomenclature, also s ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
