640505-06 The Rubus saxatilis aggregate R. pubescens, R. saxatilis
Geography: Circumboreal.
Notes: Consistent morphological and ploidy differences support species rank for the allopatric Eurasian Rubus saxatilis and the North American R. pubescens. They have the same hybridization pattern with their respective counterparts in the R. arcticus aggregate: R. x paracaulis Bailey (R. acaulis x R. pubescens) and R. x castoreus Laest. (R. arcticus s. str. x R. saxatilis). These are best treated as hybrid swarms and not as independent taxa.
