Very short, hairy annual, growing in light sandy soil.
No interactions present.
We unfortunately don't see the full plant, but colour of the young flowers suggests this is M. discolor subsp. dubia, which occurs in dampish/peaty places. I note the locality is called "Humberland Peatlands".
So the provided habitat description of "growing in light sandy soil" I find a little puzzling.
Alan, the area is a National Nature Reserve consisting largely of Peat bogs and drains. There is however a section of the reserve, especially around the main car park that does consist of sandy soil. Hope this clears the matter up. Gary
