Editing Linaceae (section)

== Taxonomy ==
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]].

In addition to their growth habits and geographic distributions, the two subfamilies can be differentiated by the number of fertile stamens (five in the Linoideae, ten in the Hugonioideae) and fruit type (capsules in the Linoideae, fleshy drupe-like fruits in the Hugonioideae).

=== Subfamily Linoideae ===
The largest genus of the Linoideae is ''[[Linum]]'', the flaxes, with 180–200 species including the cultivated [[flax]], ''L.&nbsp;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.

=== Subfamily Hugonioideae ===
The Hugonioideae subfamily is often recognized as a distinct family, the '''Hugoniaceae'''.

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.
