Fragaria iturupensis
Fragaria iturupensis, the Iturup strawberry, is a species of wild strawberry, endemic to Iturup in the Kuril Islands. It is noted to have relatively large berries for a wild species, similar in appearance to those of Fragaria virginiana.Polyploidy
All strawberries have a base haploid count of 7 chromosomes. Fragaria iturupensis was initially reported as octoploid, but subsequent testing found decaploids. It is unclear whether the earlier report was an error, or whether two forms exist.
