hybrid
A hybrid is a crossbreed between parents of different
taxa. Hybrids are frequently denominated with a "x" or "X" in the
scientific names. The parents mostly belong to the same
genus (e. g. in
Salix x
sepulcralis, a crossbreed between
Salix alba and
Salix babylonica). However, also hybrids with parents from different
genera exist: for instance, X
Calammophila baltica is a crossbreed between
Ammophila arenaria and
Calamagrostis epigejos.
