A very small plant is hidden in short dry grass. Bastard toadflax (
Thesium humifusum)
is only a few centimeters high and nearly invisible except for some miniature flowers like tiny white stars.
If you really search for it between the tangle of grass and mosses you'll find a pivotal root from which radiate several flowering stems. The yellow-green leaves and stems are a bit rounded, like those of a succulent plant (but probably you need a magnifying glass to see this).
