What is this plant in a wall?

Observed: 17th January 2011 By: Lucy CorranderLucy Corrander’s reputation in PlantsLucy Corrander’s reputation in PlantsLucy Corrander’s reputation in Plants

Plant with runners and lots of small green leaves growing in crack in stone wall. One of many of the same kind.
Neither garden nor park but tall urban wall where this (and other plants) have taken root.
The leaves have a very slight gloss to them and are about 1cm - 1.5 cm.

Species with which Pellitory-of-the-wall (Parietina judaica) interacts

Looks like Marjoram

or Oregano family ... did the leaves smell when crushed?

Thank you Camelhuish and Allison for your suggestions.

I went back today to look at the plant and the leaves aren't as long as I think they would be if it were Parietaria judaica nor are the stems hairy - though they are red.

I didn't crush the leaves but I have grown marjoram in the garden and, althoug I know there are different forms, it didn't strike me that it looks like any of them. Next time I pass I will take a sniff though!

There's masses of it in different places on these very high walls and nearby. I suspect it's an escapee from a garden somewhere that has found a good habitat and is making the most of it - though the other plants in the wall are either grass or what one might (though not here!) describe as 'weeds'.
