Hybrids between species should have scientific names (the name associated with the taxon) following the pattern GENUS SPECIES1 × SPECIES2, e.g. Dryobates nuttallii × scalaris for a hybrid between Dryobates nuttallii and Dryobates scalaris. The rank for such hybrids should be set to "hybrid." Note that the cross character is "×" and not the Roman letter "x."

Changed to reflect iNaturalist naming scheme.
