White flowers about 10 mm across. Rather rounded, heart-shaped leaves are a deep, shiny green. Fruits are small and round.
No interactions present.
Do you have any close up photo's of the leaves and flowers as it would help confirm the identification.
I don't have any at the moment but can try to get some - I'm not at all good at close-ups.
If successful, can they be added to the picture above or will I need to make a new observation?
No they can be added to your original observation,you just click on the edit tab.I know other's have agreed but I always think it is good to add close up shots too,plus you would probably have more agreements as were not all experts.
I've added two more photos that I hope will show more detail and enough to be certain of identification. I take your point about adding close-ups.
