Confidence: I'm as sure as I can be.
Notes: I don't see any sign of either R. agrestis (a nice but rare species) or R. pimpinellifolia in this. As Cicuta58 has said, maybe this a misunderstanding from iSpot names? As far as I can see this is something in the R. canina group, maybe R. canina itself, but important characters are not visible or not developed yet. Fruiting material is needed. Pure white flowers are not unusual in this group.
