The stem leaves which grew together near the basis and altered in a kolokolchaty, gustovolosisty obvyortka, rassechyonny on narrow, turning green in the top part of a segment.

The taken and recommended protection measures. Control of dynamics of populations, and if necessary — creation of microwildlife areas is necessary.
