Discussion

Ranunculus repens is widely naturalized in many parts of the world. Plants with sparse pubescence have been called R. repens var. glabratus. Horticultural forms with the outer stamens transformed into numerous extra petals occasionally become established and have been called R. repens var. pleniflorus. These variants have no taxonomic significance.
