Rubus pubescens is recognized by its creeping, unarmed stems, oblanceolate to lance-ovate stipules, relatively small flowers, and white to pink petals. It hybridizes with R. arcticus subsp. acaulis in areas of sympatry, and the hybrids are referable to R. ×paracaulis L. H. Bailey [= R. pubescens var. paracaulis (L. H. Bailey) B. Boivin]. The hybrids are similar to R. arcticus subsp. acaulis in having more obovate, rounded leaflets, and larger, pink to magenta petals; they are larger, creeping, and have hairy and stipitate-glandular pedicels and sepals like R. pubescens.
