Rubus nessensis is a species of bramble native to Northwestern Europe, including Great Britain and Ireland. Two subspecies are recognized: R. n. nessensis and R. n. cubirianus. [1]
Rubus nessensis is an erect, arching shrub growing to a height of 2 (rarely 3) metres. In its more usual shaded habitat, its stem is green; plants exposed to more light have brownish stems. Purple, conical prickles are numerous on the stem. Leaves bear 5 to 7 leaflets, the terminal leaflet being around 10 cm long, among the largest in the genus. The fruit is dark red, thus distinguishing Rubus nessensis from other members of Rubus subgenus Rubus , except Rubus scissus , which lacks the conical prickles. [2]
Rubus nessensis is found in riverside woodland, where it can dominate the ground flora. It occurs widely across Northwestern Europe. In Great Britain it has a broad distribution, with strongholds along the south coast, in South Wales, and in Argyll. Most Irish records are from the eastern half of the country. [2]
Rubus is a large and diverse genus of flowering plants in the rose family, Rosaceae, subfamily Rosoideae, with over 1,350 species.
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.
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. The fruits include blackberries, arctic brambleberries or raspberries depending on the species and are used to make jellies, jams and preserves.
Rubus spectabilis, the salmonberry, is a species of bramble in the rose family Rosaceae, native to the west coast of North America from west central Alaska to California, inland as far as Idaho. Like many other species in the genus Rubus, the salmonberry plant bears edible fruit, typically yellow-orange or red in color, resembling raspberries in appearance.
Rubus saxatilis, or stone bramble, is a species of bramble widespread across Europe and Asia from Iceland and Spain east as far as China. It has also been found in Greenland.
Rubus cockburnianus, the white-stemmed bramble, is a species of flowering plant in the family Rosaceae. It is endemic to China.
Rubus parvifolius, called Japanese bramble, or Australian raspberry in the United States or native raspberry in Australia is a species of plant in the rose family. It is a scrambling shrub native to eastern Asia and Australia. It has also become naturalized in a few scattered locations in the United States.
Rubus ulmifolius is a species of wild blackberry known by the English common name elmleaf blackberry or thornless blackberry and the Spanish common name zarzamora. It is native to Europe and North Africa, and has also become naturalized in parts of the United States, Australia, and southern South America.
Rubus flagellaris, the northern dewberry, also known as the common dewberry, is a North American species perennial subshrub species of dewberry, in the rose family. This dewberry is distributed across much of Canada, Mexico, and the United States. It grows in diverse habitats ranging from drier savannas to temperate deciduous forests.
Rubus adenophorus is a species of deciduous shrub in the genus Rubus in the family Rosaceae native to China, where it was discovered in 1907. It is distinctive for its black-headed glands mixed with bristles on the stems.
Rubus cubitans, the sprawling dewberry, is a rare North American species of flowering plant in the rose family. It has been found only in the State of Vermont in the northeastern United States.
Rubus roribaccus a North American species of brambles in the rose family, called the Lucretia blackberry. It grows in eastern Canada (Québec) and the eastern and central United States.
Rubus adenotrichos is a Mesoamerican species of brambles in the rose family. It grows in Central America, northwestern South America, and central and southern Mexico, from Michoacán and Veracruz south to Ecuador and Venezuela.
Rubus durescens is a rare British species of flowering plant in the rose family. It is native to England, where the entire global distribution of this bramble is found only within the southern half of the county of Derbyshire. It occurs in hedges, shrubs, wood and heathy areas, and was first described and named in 1892 by the Derbyshire botanist William Richardson Linton. Linton placed an illustration of the plant in gold leaf on the cover of the 1903 version of The Flora of Derbyshire, of which he was the sole author.
Rubus calvatus is a species of bramble endemic to the British Isles.
Rubus anglocandicans is a species of bramble endemic to England.
Rubus septentrionalis is a species of bramble widely distributed in Northern Europe. It grows at higher latitudes than most other brambles.
Rubus gratus is a species of bramble found across much of Northwest Europe.
Rubus dasyphyllus is a species of bramble found in northwest Europe, including Belgium, Denmark, Germany, the Netherlands, and the British Isles. It may be extinct in Sweden.
Rubus pyramidalis is a species of bramble, a flowering plant in the rose family, native to northwest Europe.
