- Query IPNI
- Common Name: Meadow Horsetail
- Family: Equisetaceae Rich. ex DC
- Country of Origin: circumboreal
- Habitat: Grassy stream banks, up to 900m
- Description: [syn. Equisetum umbrosum J.G.F. Meyer ex Willd.]
This species, although having the same distribution as others such as E. palustre, E. fluviatile and E. sylvaticum, is less frequent than they are. Its deltoid branch teeth on horizontal to drooping branches make it distinctive enough that it has been generally recognized since the early 19th century. It appears nearly uniform throughout its range, being slightly more robust in Europe than in North America, and having greater silicification and occasionally 4-angled branches in Siberia and northern China.
