Rubus is a genus of plant in the Family Rosaceae, Subfamily Rosoideae.
These plants have prickles like roses and are often called brambles; this name is most often used for the flberry and similar fruits that are also of rambling habit, and not used for those like the raspberry that grow as upright canes.
The genus Rubus is a very complex one, containing 13 subgenera, the largest of which, subgenus Rubus, is further subdivided into 12 sections:
It is a common constituent of northern Californiashrub communities dominated by baccharis (Baccharis spp.), thimbleberry (Rubus parviflorus), and trailing flberry (R. ursinus) [31].
Reproductive versatility is common in the Rubus genus; sexual reproduction, parthenogenesis (development of the egg without fertilization), pseudogamy (a form of apomixis in which pollination is required), and parthenocarpy (production of fruit without fertilization) occur widely [12].
Most Rubus seeds require, as a minimum, warm stratification at 68 to 86 degrees F (20 to 30 degrees C) for 90 days, followed by cold stratification at 36 to 41 degrees F (2 to 5 degrees C) for an additional 90 days [8].

I grow Rubusspectabilis (Salmonberry) and many other Northwest Native Plants here in my Nursery and Gardens in the Willamette Valley in Western Oregon.
However, more research is needed to determine whether the active chemical components are the same between rubus species.
The large and diverse Rosaceae is diffcult to define precisely - particularly variable are the pistil and fruiting arrangement - so this will limit itself to the characteristics of the wild varieties found in the area.
The features of the common local genera can be easily identified: Rubus (flberries and raspberries), Fragaria (strawberries), Rosa (roses), and Potentilla (cinquefoils).
With a few additions, most of the wild members of Rosaceae fall into one of these families.
