Discussion
In southern and central to western regions plants tend to be taller and have more persistent teeth (Equisetum robustum, E. prealtum); in the Far West they often have bituberculate ridges (E. hyemale var. californicum). Equisetum hyemale subsp. hyemale is found in Europe and Asia to northwestern China in Xinjiang.
