[Espèces (in biblio)] Equisetum x meridionale [Espèces (in biblio)] Equisetum x trachyodon Résumé : "Hybrid horsetails in Equisetum subgenus Hippochaete are superficially similar. Distinguishing the different taxa depends on the micromorphology of the stem ridges. In the case of the hybrids E. ×trachyodon (E. hyemale×E. variegatum) and E. ×meridionale (E. ramosissimum×E. variegatum) both inherit silica tubercles that run vertically along the stem ridges but only E. ×meridionale has silica cross-bands on the stem ridges; these are difficult to discern in the field, even with a ×20 hand-lens and good light. The past misidentification of some populations of E. ×meridionale as E. ×trachyodon in the British Isles is therefore understandable. Recorded populations of E. ×trachyodon in England are re-assessed, with some found to be E. ×meridionale. Associated species and habitats are compared. Using flow cytometry, all known British populations of E. ×meridionale were determined to be diploid. An identification key which incorporates recent knowledge of the morphology of the species and hybrids in subgenus Hippochaete in Europe is presented."
