Leymus mollis ssp. villosissimus
Discussion:
Genome composition: NsXm (Wang and Hsiao 1984). The studied accession, based on material collected near Anchorage, Alaska, was not determined to an infraspecific rank, but likely represents Leymus mollis ssp. mollis given its provenanance. Leymus mollis ssp. villosissimus apparently has not been studied cytologically.
Species name etymology:
The epithet villosissimus refers to the taxon's densely villous or lanate glumes.
