Spotting

Thank you very much, John! I was really wondering about this one! That looks just like it! You can suggest an identification if you would like.

This is a bizarre plant. It took a bit of research to come up with a likely suspect. Violets with notched petals are uncommon even outside this country, and I've never seen an individual with basically cleft parts like this. Based on the photograph, a positive ID is probably impossible (at least from me, I'm not a Viola specialist), but I believe this is some variety, forma, or defective individual of Viola renifolia. The leaves might provide a positive ID, but unfortunately, these were yet unfurled. Still, they have the same general appearance and the flower structure is the same as well - apart from the cleft petals and dull lip-vein coloring.

Anyway, cool plant! That's not one you see every day.
