A very variable species particularly in the shape and size of leaves, length of petiole and fruit size. Often split into a number of infraspecific categories. However, the variation appears to form a continuum in our area. Any recognition of infraspecific taxa does not seem to be meaningful. A common weed of plains to 3500 m.
