"Rubus" is a large genus of flowering plants in the family Rosaceae, subfamily Rosoideae. 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 blackberries, as well as various other "Rubus" species with mounding or rambling growth habits, are often called brambles. 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 genus "Rubus" is believed to have existed since at least 23.7 to 36.6 million years ago. [ [] ]

Examples of the hundreds, if not thousands, of species of "Rubus" include:

*"Rubus allegheniensis" – Allegheny Blackberry
*"Rubus arcticus" – Arctic Raspberry
*"Rubus armeniacus" – Himalayan Blackberry
*"Rubus caesius" – European Dewberry
*"Rubus canadensis" – Canadian Blackberry
*"Rubus chamaemorus" – Cloudberry
*"Rubus coreanus" - Bokbunja
*"Rubus cuneifolius" – Sand Blackberry
*"Rubus fruticosus" agg. – Blackberry
*"Rubus idaeus" – European Red Raspberry
*"Rubus leucodermis" – Whitebark Raspberry or Western Raspberry
*"Rubus occidentalis" – Black Raspberry
*"Rubus odoratus" – Flowering Raspberry
*"Rubus parviflorus" – Thimbleberry
*"Rubus pensilvanicus" – Pennsylvania Blackberry
*"Rubus phoenicolasius" – Wineberry
*"Rubus saxatilis" – Stone Bramble
*"Rubus spectabilis" – Salmonberry
*"Rubus strigosus" – American Red Raspberry

The genus also includes numerous hybrids, both natural and bred by man, such as the Loganberry ("Rubus × loganobaccus").

Scientific classification

The genus "Rubus" is a very complex one, particularly 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. 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" and "R. strigosus" both recognized; if these species are combined, then the older name "R. idaeus" has priority for the broader species.)

Molecular data has backed up classifications based on geography and chromosome number, but following morphological data such as the structure of the leaves and stems does not appear to produce a phylogenetic classification.

Campbell | journal = American Journal of Botany | year = 1999 | volume = 86 | pages = 81–97 | doi = 10.2307/2656957 ]

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 there are many more species not mentioned here.
