Rubus bartonianus, or Barton's raspberry, is an uncommon North American species of flowering plant in the rose family.
Description The shrub grows up to tall, with deciduous leaves up to long. The flowers have five white petals, which are each long. The dark red fruit resembles a raspberry.
Taxonomy The species is named for Mrs. Ralph Barton of Wallowa County, Oregon, who brought the plant to the attention of botanist Morton Eaton Peck.Peck, Morton Eaton. 1934. Rhodora 36(427): 267–268 description in Latin, commentary in English
The genetics of Rubus is extremely complex, so that it is difficult to decide on which groups should be recognized as species. There are many rare species with limited ranges such as this. Further study is suggested to clarify the taxonomy.Flora of North America, Rubus Linnaeus, 1754. Bramble
Distribution and habitat It is found only in north-central Idaho and northeastern Oregon in the northwestern United States.Biota of North America Program 2014 county distribution map It grows near streams and on rocky slopes in partial shade and after fire.
