Abstract
Silicified leaf‐sheath fragments of Equisetum sp. are described from Late Tertiary strata in west‐central Nebraska. The close affinity of these fossils to the subgenus Hippochaetae is supported by the presence of sunken stomata arranged in two regular rows on each leaf‐sheath segment. This is the first report of the genus Equisetum from the late Tertiary Ash Hollow Formation of central North America.
