'''Linaceae''' is a [[family (biology)|family]] of [[flowering plant]]s. The family is [[cosmopolitan distribution|cosmopolitan]], and includes about 250 species in 14 genera, classified into two subfamilies:  the Linoideae and Hugonioideae (often recognized as a distinct family, the Hugoniaceae).
 
Leaves of the Linaceae are always simple; arrangement varies from alternate (most species) to opposite (in ''Sclerolinon'' and some ''Linum'') or whorled (in some ''Hesperolinon'' and ''Linum'' species). The [[hermaphroditic]], [[actinomorphic]] flowers are [[Pentamery (botany)|pentameric]], or very rarely [[tetramery (botany)|tetramer]]ic (e.g. ''Radiola linoides'', ''Linum keniense'').
 
 
 
In the Linoideae, the largest genus is ''[[Linum]]'', the flaxes, with 180-200 species including the cultivated [[flax]], ''Linum usitatissimum''. Members of the Linoideae include herbaceous annuals and perennials, as well as woody subshrubs, shrubs, and small trees (''Tirpitzia'') inhabiting temperate and tropical latitudes of Eurasia, Africa, Australia, and the Americas.  The largest genus of the Hugonioideae is ''Hugonia'' (about 40 species); the Hugonioideae are woody vines, shrubs, and trees, and are almost entirely tropical in distribution.  In addition to their growth habits and geographic distributions, the Linoideae and Hugonioideae can be differentiated by the number of fertile stamens (five in the Linoideae, 10 in the Hugonioideae) and fruit type (capsules in the Linoideae, fleshy drupe-like fruits in the Hugonioideae).

Under the old [[Cronquist system]] of classifying the [[flowering plants]], the Linaceae were placed in their own [[order (biology)|order]], the [[Linales]]. Modern classifications place them in the order [[Malpighiales]].
