Growing on path in shade of trees.

Difficult to tell the scale from this.
The leaves are approximately 10mm in circumference and almost round. They have clear veins, a few gentle teeth and are bright shiny green. The plant is mainly leaf with only small group of minute white flowers growing in a small terminal cluster in the leaf axis.
Soleirolia soleirolii has solitary flowers, so the above description excludes this.
Terminal is a technical term in botany, and it means that the organ so described is situated at the end of a shoot, as opposed to axillary (in the leaf axils), oppositifoliate or internodal. Do you mean a long-pedunculate axillary inflorescence (flowers on a long common stalk growing from a leaf axil)?
Veronica serpyllifolium and Veronica repens have terminal inflorescences.
Sorry, I am new to botany and was using terminal in the everyday sense of the word to mean at the end of a branch. I have been back to the site and brought home a specimen of the plant with the tiny flowers and added a picture with a scale to I-spot. I hope this clarifies what I was trying to say.
Doesn't look like Soleirolia soleirolii, the leaves would be sparsely hairy and have the appearance of a warty surface, see these observations; http://www.ispot.org.uk/node/333324 and http://www.ispot.org.uk/node/341197.
As landgirl says an idea of scale would help.
I wondered about Lysimachia nummularia, but this plant has slightly crenate leaves. Then I considered Veronica montana, but it doesn't look hairy enough. Not sure!
Yes, I don't think it can be Lysimachia nummularia. I did think Veronica serpyllifolia ssp. humifusa, short petiole and glabrous leaves, but wrong part of the country. Perhaps could it be the Corsican Speedwell, Veronica repens, very similar to V.serpyllifolia ssp. humifusa ?
It does look like images of this, although I don't know it myself. Difficult to see how it would get to this location though!
