Equisetum variegatum var. Jesupi A. A. Eaton, Fern Bull. 12: 24. 1904.

This variety has some of the characters of H. variegata, towards which it trends. The teeth have long, generally persistent awns and the anatomy is variable, sometimes of one type, sometimes of the other. The size and aspect are intermediate but the tight, cylindrical sheaths place it with H. hyemalis rather than with H. variegata.
