It is a diverse genus, and estimates of the number of ''Rubus'' species vary from 250 to over 1,000, found across all continents except Antarctica.

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.<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|url-access=subscription }}</ref>

''Rubus'' is very complex, particularly within the blackberry/dewberry subgenus (''Rubus''), with polyploidy, hybridization, and facultative apomixis apparently all frequently occurring, making species 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="Huang-2023">{{Cite journal |last1=Huang |first1=Ti-Ran |last2=Chen |first2=Jian-Hui |last3=Hummer |first3=Kim E. |last4=Alice |first4=Lawrence A. |last5=Wang |first5=Wen-He |last6=He |first6=Yi |last7=Yu |first7=Sheng-Xiang |last8=Yang |first8=Ming-Feng |last9=Chai |first9=Tuan-Yao |last10=Zhu |first10=Xiang-Yun |last11=Ma |first11=Lan-Qing |last12=Wang |first12=Hong |date=April 2023 |title=Phylogeny of Rubus (Rosaceae): Integrating molecular and morphological evidence into an infrageneric revision |url=https://onlinelibrary.wiley.com/doi/10.1002/tax.12885 |journal=Taxon |language=en |volume=72 |issue=2 |pages=278–306 |doi=10.1002/tax.12885 |bibcode=2023Taxon..72..278H |issn=0040-0262|url-access=subscription }}</ref>

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 ''R. idaeus'' and ''R. strigosus'' both recognized; if these species are combined, then the older name ''R. 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 sections. Representative examples are presented, but many more species are not mentioned here. A 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 |article-number=1615 |doi=10.3389/fpls.2019.01615 |issn=1664-462X |pmc=6933950 |pmid=31921259 |doi-access=free|bibcode=2019FrPS...10.1615C }}</ref>

==== 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 apomicts (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. ursinus'', ''R. fruticosus'') and raspberries (''R. 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=usurped }}</ref>

The hybrid berries include:-<ref>{{cite journal |last=Ardle |first=John |title=Hybris vigour |journal=The Garden |date=July 2013}}</ref> * loganberry (California, U.S., 1883) ''R.'' ×''loganobaccus'', a spontaneous hybrid between ''R. ursinus'' 'Aughinbaugh' and ''R. idaeus'' 'Red Antwerp' * boysenberry (U.S., 1920s) - a hybrid between ''R. idaeus'' and ''R.'' × ''loganobaccus'' * nectarberry - a suspected variant of boysenberry, a hybrid between ''R. idaeus'' and ''R.'' × ''loganobaccus'' * olallieberry (U.S., 1930s) - a hybrid between the loganberry and youngberry, themselves both hybrid berries * veitchberry (Europe, 1930s) - a hybrid between ''R. fruticosus'' and ''R. idaeus'' * skellyberry (Texas, U.S., 2000s) - a hybrid between ''R. invisus'' and ''R. phoenicolasius'' * marionberry (1956) - now thought to be a blackberry cultivar ''R.'' 'Marion' * silvanberry - ''R.'' 'Silvan', a hybrid between ''R.'' 'Marion' and boysenberry * tayberry (Dundee, Scotland, 1979) - another blackberry/raspberry hybrid * tummelberry, ''R.'' 'Tummel' - from the same Scottish breeding programme as the tayberry * hildaberry (1980s) - a tayberry/boysenberry hybrid discovered by an amateur grower * youngberry - a complex hybrid of raspberries, blackberries, and dewberries

=== 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 brambles.<ref name=":0">{{Cite web|url=https://www.woodlandtrust.org.uk/trees-woods-and-wildlife/plants/wild-flowers/bramble/|title=Bramble |website=Woodland Trust |access-date=20 February 2025 |archive-url=https://web.archive.org/web/20241220022318/https://www.woodlandtrust.org.uk/trees-woods-and-wildlife/plants/wild-flowers/bramble/ |archive-date=20 December 2024 }}</ref> 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 "batology". "Bramble" comes from Old English ''bræmbel'', a variant of ''bræmel''.<ref name="dict" />
