Rubus deliciosus
Rubus repens
Rubus deliciosus is recognized by its decumbent to erect, unarmed stems, relatively small simple leaves with obtuse to broadly rounded lobes, shallowly cordate bases, sparsely hairy abaxial surfaces, large flowers, white petals, glabrous or sparsely hairy sepals, and densely villous clavate styles. The distinction between R. deliciosus and R. neomexicanus is not always clear, especially when the former has more narrowly obtuse lobes and denser leaf abaxial hairs. Rubus deliciosus is also similar to R. bartonianus of Idaho and Oregon, as well as the Mexican R. trilobus Seringe. It might be reasonable to recognize a broader concept of R. deliciosus, one containing multiple infraspecific. Rubus deliciosus and its close relatives require a revisionary study.
Rubus deliciosus has long been planted for its ornamental value because of its large, showy flowers.

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).
