Notes:

Very variable. Local forms are close to the following varieties: (a) var. simplex (Doll) Milde, Sporenpfl. 118 (1865): stems without or with 1-2 lateral branches, 8-16-ridged. (b) var. procerum (Poll.) Asch. in Asch. & Graebn., Syn. 1: 140 (1896): stems with 3-8 lateral branches, 8-16-ridged. (c) var. altissimum Milde, 1.c. 117: stems with many long branches, 14-20-ridged.

As there are transitions between these varieties, their taxonomic status is questionable at present.

Stems and branches are relatively rich with silicon. Occasionally used in popular medicine.
