Family Linaceae (order Linales), composed of about 14 genera of herbaceous plants and shrubs found throughout the world.
The genus Linum includes flax, perhaps the most important member of the family, grown for linen fibre and linseed oil and as a garden ornamental. Reinwardtia species are primarily low shrubs, grown in greenhouses and outdoors in warm climates; R. indica , yellow flax, is notable for its large yellow flowers, borne in profusion in late fall and early winter.
