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.

Subspecies affine is found throughout subarctic Alaska, including the Aleutian Islands.
