Description: hybrid scouring rush, Equisetum Xferrissii, White Mountains, elevation 1565 m (5135 ft). From Hauke (1993, Flora of North America vol. 2): "The hybrid between Equisetum hyemale and E. laevigatum.. Although sterile,.. exists outside the range of E. laevigatum, and apparently it is dispersed vegetatively.." In the White Mountains E. laevigatum is somtimes found in the same drainage, but often E. Xferrisii is the only scouring rush present. Date: 27 August 2012, 13:33. Source: hybrid scouring rush, Equisetum Xferrissii. Author: Jim Morefield from Nevada, USA.
