'''Cannabaceae''' is a small [[family (biology)|family]] of [[flowering plant]]s.<br />
<br />
According to the [[Royal Botanical Gardens]] database, there are 170 species grouped in nine to fifteen genera, including three well-known genera ''[[Cannabis]]'' (hemp), ''[[Hop (plant)|Humulus]]'' (hops) and ''[[Hackberry|Celtis]]'' (hackberries). ''[[Celtis]]'' is by far the largest genus, counting 100 species. <br />
<br />
== Taxonomy ==<br />
<br />
Cannabaceae used to be part of the order [[Urticales]], which is now included into [[Rosales]]. The family is closely allied with the other families of the old Urticales, [[Moraceae]], [[Urticaceae]], and [[Ulmaceae]]. The old Urticales are sister to the rest of Rosales.<br />
<br />
''Celtis'' is peculiar among Cannabaceae, as it is a tall tree and it is not dioecious. It was previously included either in the strictly related family [[Ulmaceae]] (the [[Ulmus|elm]] family) or their own family the Celtidaceae, and has been recently included into Cannabaceae by the [[Angiosperm Phylogeny Group]] after genetic analysis.<br />
<br />
==Description==<br />
Cannabaceae are very similar to [[Moraceae]]. Members of this family can be trees (e.g. ''[[Celtis]]''), erect or twining herbs (e.g. ''[[Cannabis]]'' and ''[[Humulus]]'' respectively). <br />
<br />
'''[[Leaf|Leaves]]''' are often more or less palmately lobed or palmately compund and always bear [[stipule]]s. [[Cystolith]]s are always present and some members of this family are [[laticifer]]s. <br />
<br />
Cannabaceae are often [[plant sexuality|dioecious]] (distinct male and female plants). The '''flowers''' are [[actinomorphic]] (radially symmetrical) and not showy, as these plants are [[anemophyly|pollinated by the wind]]. As an adaptation to this kind of pollination, the [[calyx (botany)|calyx]] is short and there is no [[corolla]]. Flowers are grouped to form [[cyme]]s. In the dioecious plants the masculine inflorescences are long and look like [[panicle]]s, while the feminine are shorter and bear less flowers.The [[pistil]] is made of two connate [[carpel]]s, the usually superior ovary is unilocular; there is no fixed number of [[stamen]]s.<br />
<br />
The fruit can be an [[achene]] or a small [[nut]].<br />
<br />
== Uses ==<br />
[[Hop]] (''Humulus lupulus'') is cultivated for its fruits which contain aromatic substances used in the production of [[beer]]. Its young shoots are used as vegetable. Different subspecies of [[hemp]] (''Cannabi sativa'') are cultivated for the production of fiber, as a source of cheap [[hemp oil|oil]] or to produce recreational and medicinal [[cannabis (drug)|marijuana]].<br />
