Salomon, B. 2005: Deviating variants of
Elymus caninus (Poaceae) in NW Europe.
Willdenowia 35: 245-251.

Abstract
The variation in Elymus caninus in NW Europe is
briefly discussed. On the one hand, three short-awned taxa described
from this area, with the epithets donianus, behmii and
muticus, are considered to be conspecific with the
long-awned E. caninus var. caninus.
The three taxa represent morphologically deviating populations, which
are best treated at varietal level, if desirable to recognize them at
all. They are, however, doubtfully distinct from each other. On the
other hand, the Icelandic populations of E. caninus
have been shown to be morphologically, geographically, reproductively
and genetically deviating from all other investigated populations of
this species. Hence, they are described here as a new species,
E. alopex. A key to the accepted non-littoral
Elymus taxa in NW Europe is provided.
