Rubus ursinus Cham. & Schltdl.[FNA9, HC, HC2]
Pacific blackberry, trailing blackberry, dewberry, Douglasberry
Publication: Linnaea 2: 11. 1827.
Origin: Native
Herbarium search: CPNWH
Notes: Draft FNA9: "Rubus ursinus is often reminiscent in habit of the predominantly eastern North American but non-sympatric R. flagellaris, and is likewise polymorphic. Of agricultural significance, R. ursinus is a parent of several important cultivars, including loganberry and boysenberry.
See discussion under Rubus flagellaris for the superficially similar R. caesius. See discussion under R. spectabilis for the application of the name R. menziesii."
