The laserwort

After the bridge, a large plant with flowers arranged in umbels (in other words, an umbellifer) clings to a small rock bar to the right of the track, the laserwort. This plant belongs to the family Apiaceae, which used to be called umbellifers, and grows in dry areas. It has a distinctive feature: in autumn, the basal part of the stem breaks of its own accord and the entire plant, now dry, sets off rolling down the hillside like a large ball, or is blown by the wind.
