"[An Indo-European] word for 'flax' (*linom) is confined to ... northwest Europe (Celtic, Italic, Baltic, Slavic, possibly Germanic) and Greece. Flax (Linum usitatissimum) was domesticated quite early in southwest Asia and is found on Neolithic sites at least from central and northern as well as southern Europe but is not recorded until quite late in the regions north of the Black Sea." ~ Mallory & Adams, Encyclopedia of Indo-European Culture (1997)
