Rubus bartonianus
Rubus repens
Of conservation concern.
Rubus bartonianus is distinguished from the other flowering raspberries within its geographic range by its erect, unarmed stems, relatively small, simple leaves with acute to obtuse lobes, deeply cordate bases, sparsely hairy or glabrous abaxial surfaces, relatively large flowers with white petals, and densely long-hairy, clavate styles. The leaves superficially resemble those of Acer glabrum or some species of Ribes.
Rubus bartonianus is most similar to R. neomexicanus but especially R. deliciosus. The species is known only from the Snake River Canyon of Idaho and Oregon.

Rubus repens is recognized by its creeping, unarmed stems, simple, ovate-orbiculate leaves, long petioles with spreading hairs, sterile petaliferous flowers on long pedicels and fertile apetalous flowers on short pedicels, and essentially dry fruits. Phylogenetic analysis of DNA sequence data supports inclusion of D. repens in Rubus (L. A. Alice and C. S. Campbell 1999), among other basal species to R. lasiococcus (K. V. Ambrose 2006).
The Iroquois use a decoction of powdered plants of Rubus repens as a blood purifier and for venereal disease (J. W. Herrick 1977).
