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 fruit|aggregate]] of [[drupelet]]s. The term "cane fruit" or "cane berry" applies to any ''Rubus'' species or [[Hybrid (biology)|hybrid]] which is commonly grown with supports such as wires or canes, including raspberries, blackberries, and hybrids such as [[loganberry]], [[boysenberry]], [[marionberry]] and [[tayberry]].<ref name=GYOF>{{cite book |last=Klein |first=Carol |title=Grow your own fruit |year=2009 |publisher=Mitchell Beazley |location=United Kingdom |isbn=978-1-84533-434-5 |pages=224}}</ref> The stems of such plants are also referred to as canes.

==Taxonomy==
=== Modern classification ===
''Rubus'' is the only genus in the tribe Rubeae.<ref>{{Cite journal |last1=Chen |first1=Xun |last2=Li |first2=Jinlu |last3=Cheng |first3=Tao |last4=Zhang |first4=Wen |last5=Liu |first5=Yanlei |last6=Wu |first6=Ping |last7=Yang |first7=Xueying |last8=Wang |first8=Ling |last9=Zhou |first9=Shiliang |date=February 2020 |title=Molecular systematics of Rosoideae (Rosaceae) |url=http://link.springer.com/10.1007/s00606-020-01629-z |journal=Plant Systematics and Evolution |language=en |volume=306 |issue=1 |page=9 |doi=10.1007/s00606-020-01629-z |bibcode=2020PSyEv.306....9C |issn=0378-2697}}</ref>

''Rubus'' is very complex, particularly within the [[blackberry]]/[[dewberry]] [[subgenus]] (''Rubus''), with polyploidy, [[Hybrid (biology)|hybridization]], and facultative [[apomixis]] apparently all frequently occurring, making species [[Taxonomy (biology)|classification]] of the great variation in the subgenus one of the grand challenges of [[systematic botany]]. In publications between 1910 and 1914, German botanist [[Wilhelm Olbers Focke]] attempted to organize the genus into 12 subgenera, a classification system that since became widely accepted, though modern genetic studies have found that many of these subgenera are not [[monophyletic]].<ref name=":0" />

Some treatments have recognized dozens of species each for what other, comparably qualified botanists have considered single, more variable species. On the other hand, species in the other ''Rubus'' subgenera (such as the [[raspberries]]) are generally distinct, or else involved in more routine one-or-a-few taxonomic debates, such as whether the European and American red raspberries are better treated as one species or two (in this case, the two-species view is followed here, with ''[[Rubus idaeus|R.&nbsp;idaeus]]'' and ''[[Rubus strigosus|R.&nbsp;strigosus]]'' both recognized; if these species are combined, then the older name ''R.&nbsp;idaeus'' has priority for the broader species).

The classification presented below recognizes 13 subgenera within ''Rubus'', with the largest subgenus (''Rubus'') in turn divided into 12 [[Section (botany)|sections]]. Representative examples are presented, but many more species are not mentioned here. A&nbsp;comprehensive 2019 study found subgenera ''Orobatus'' and ''Anoplobatus'' to be [[monophyletic]], while all other subgenera to be [[paraphyletic]] or [[polyphyletic]].<ref name="Carter-2019">{{Cite journal |last1=Carter |first1=Katherine A. |last2=Liston |first2=Aaron |last3=Bassil |first3=Nahla V. |last4=Alice |first4=Lawrence A. |last5=Bushakra |first5=Jill M. |last6=Sutherland |first6=Brittany L. |last7=Mockler |first7=Todd C. |last8=Bryant |first8=Douglas W. |last9=Hummer |first9=Kim E. |date=2019-12-20 |title=Target Capture Sequencing Unravels Rubus Evolution |journal=Frontiers in Plant Science |volume=10 |pages=1615 |doi=10.3389/fpls.2019.01615 |issn=1664-462X |pmc=6933950 |pmid=31921259 |doi-access=free}}</ref>

=== Phylogeny ===
The genus has a likely North American origin,<ref name="Carter-2019" /> with fossils known from the [[Eocene]]-aged [[Florissant Formation]] of Colorado, around 34 million years old.<ref>{{Citation |last1=Leopold |first1=Estella B. |title=Phytogeography of the late Eocene Florissant flora reconsidered |date=2008 |url=https://pubs.geoscienceworld.org/books/book/587/chapter/3804067 |work=Paleontology of the Upper Eocene Florissant Formation, Colorado |publisher=Geological Society of America |language=en |doi=10.1130/2008.2435(04) |isbn=978-0-8137-2435-5 |access-date=2021-09-23 |last2=Manchester |first2=Steven R. |last3=Meyer |first3=Herbert W. |archive-date=2024-05-24 |archive-url=https://web.archive.org/web/20240524114632/https://pubs.geoscienceworld.org/gsa/books/book/587/chapter-abstract/3804067/Phytogeography-of-the-late-Eocene-Florissant-flora?redirectedFrom=fulltext |url-status=live }}</ref> ''Rubus'' expanded into Eurasia, South America, and Oceania during the [[Miocene]].<ref name="Carter-2019" /> [[Fossil]] seeds from the early [[Miocene]] of ''Rubus'' have been found in the [[Czech Republic|Czech]] part of the [[Zittau]] Basin.<ref>Acta Palaeobotanica – 43(1): 9-49, January 2003 – Early Miocene carpological material from the Czech part of the Zittau Basin – Vasilis Teodoridis</ref> Many fossil fruits of †''Rubus laticostatus'', †''Rubus microspermus'' and †''Rubus semirotundatus'' have been extracted from bore hole samples of the [[Middle Miocene]] fresh water deposits in [[Nowy Sacz]] Basin, [[West Carpathians]], [[Poland]].<ref>Łańcucka-Środoniowa M.: Macroscopic plant remains from the freshwater Miocene of the Nowy Sącz Basin (West Carpathians, Poland) [Szczątki makroskopowe roślin z miocenu słodkowodnego Kotliny Sądeckiej (Karpaty Zachodnie, Polska)]. Acta Palaeobotanica 1979 20 (1): 3-117.</ref>

Molecular data have backed up classifications based on geography and chromosome number, but following [[Plant morphology|morphological]] data, such as the structure of the leaves and stems, do not appear to produce a phylogenetic classification.<ref>{{cite journal |author1=Lawrence A.

==== Hybrid berries ====

The term "hybrid berry" is often used collectively for those fruits in the genus ''Rubus'' which have been developed mainly in the U.S. and U.K. in the last 130 years. As ''Rubus'' species readily interbreed and are [[apomict]]s (able to set seed without fertilisation), the parentage of these plants is often highly complex, but is generally agreed to include cultivars of blackberries (''R.&nbsp;ursinus'', ''R.&nbsp;fruticosus'') and raspberries (''R.&nbsp;idaeus''). The British National Collection of ''Rubus'' stands at over 200 species and, although not within the scope of the National Collection, also hold many cultivars.<ref>[http://www.rubusspecies.com/ National Collection of ''Rubus'' Species, Houghton, England, United Kingdom] {{Webarchive|url=https://web.archive.org/web/20170912105653/http://rubusspecies.com/ |date=2017-09-12 }} ''www.rubusspecies.com''</ref><ref>{{cite web |url=http://www.nccpg.com/National-Collections/Collection-Results.aspx?id=391 |title=Plant Heritage – National Collections Scheme, UK Garden Plants |work=nccpg.com |access-date=20 January 2015 |archive-date=20 January 2015 |archive-url=https://web.archive.org/web/20150120233053/http://www.nccpg.com/National-Collections/Collection-Results.aspx?id=391 |url-status=live }}</ref>

=== Etymology ===
The generic name means blackberry in [[Latin]] and was derived from the word ''ruber'', meaning "red".<ref>{{cite book |last=Quattrocchi |first=Umberto |url=https://books.google.com/books?id=zIOvJSJs-IkC |title=CRC World Dictionary of Plant Names |publisher=Taylor & Francis US |year=2000 |isbn=978-0-8493-2678-3 |volume=IV R-Z |page=2345 |access-date=2020-12-29 |archive-date=2024-05-24 |archive-url=https://web.archive.org/web/20240524114631/https://books.google.com/books?id=zIOvJSJs-IkC |url-status=live }}</ref>

The blackberries, as well as various other ''Rubus'' species with mounding or rambling growth habits, are often called [[bramble]]s. However, this name is not used for those like the raspberry that grow as upright canes, or for trailing or prostrate species, such as most dewberries, or various low-growing boreal, arctic, or alpine species. The scientific study of brambles is known as "[[wikt:batology|batology]]".
"Bramble" comes from Old English ''bræmbel'', a variant of ''bræmel''.<ref name="dict" />
