0401 Equisetum L.
- L., Sp. Pl.: 1061 (1753).
- Hippochaete Milde, Bot. Zeitung (Berlin) 23: 297 (1865).
- Excluded: Equisetum x litorale (E. arvense x fluviatile).
Notes: Some authors consider Equisetum s. str. and Hippochaete two genera (e.g., Löve and Löve 1975a). In a phylogenetic study based on cpDNA data (rbcL and trnL-F), Des Marais et al. (2003) found Hippochaete and Equisetum (as subgenera) to be sister groups to a South American species (E. bogotense Kunth) basal to both branches. We retain Hippochaete within Equisetum.
