Probably originating from Middle East, flax plant was subsequently
introduced to several other world regions including
Europe. Disruptive selection through thousands of years of flax
domestication has resulted in its diversification into oilseed and
fibrous plant types. Both types differ substantially in phenotype
and physiology. Linseed flax grows up to 40–60 cm tall with highly
branched stem, while fibrous plant grows up to 80–120 cm and is
less branched.
