Summary: This paper presents a diachronic review of plant records of flax (Linum usitatissimum L.) and hemp (Cannabis sativa L.), both known for the dual use of their fibres for textile production and for their oil containing seeds. In addition, the finds of gold of pleasure (Camelina sativa (L.) Crantz,) is discussed. This plant was cultivated for the use of its oil oil-containing seeds for at least 2000 years but has totally fallen into oblivion.
