Rubus odoratus
Rubus repens
Rubus odoratus is introduced in Washington State. The species is distinguished from other flowering raspberries by its erect, unarmed stems, simple leaves, large flowers, magenta petals, glabrous, clavate styles, and purple stipitate glands densely covering most plant parts. A hybrid with R. nutkanus (R. ×fraseri Rehder) is thought to occur in areas of overlap in northern Michigan (E. G. Voss 1972–1996, vol. 2).
The Cherokee used leaf infusions for labor pains and the Iroquois used plant infusions for miscarriage (P. Bergner 1997). Rubus odoratus is grown as an ornamental for its relatively large flowers and magenta petals and its edible fruits that are somewhat dry and insipid.

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).
