The family name comes from the genus ''[[Urtica]]'' (nettles). Urticaceae includes a number of well-known, interesting and useful plants, including genus ''[[Urtica]]'' (nettles), ''[[Boehmeria nivea]]'' (ramie), ''[[Pipturus albidus]]'' (mamaki), and ''[[Debregeasia saeneb]]'' ([[ajlai]]). The family counts more or less 2600 species, grouped into 54 to 79 genera, according to the database of the [[Royal Botanic Gardens, Kew]]. The largest genera are ''[[Pilea]]'' (500 to 715 species), ''[[Elatostema]]'' (300 species), ''[[Urtica]]'' (80 species), and ''[[Cecropia]]'' (75 species). Urticaceae can be found worldwide, apart from the polar regions. == Taxonomy == [[Angiosperm Phylogeny Group|APG II system]] puts Urticaceae in order Rosales, while older system consider it part of [[Urticales]], along with [[Ulmaceae]], [[Moraceae]] and [[Cannabaceae]]. APG still considers "old" Urticales a monophyletic group, but does not recognise it as an order on its own. == Description == [[Image:Urtica flowerdiagram.png|thumb|Male and female flower of ''Urtica''|left]] Urticaceae can be shrubs (e.g. ''Pilea''), lianas, herbs (e.g. ''Urtica''. ''Parietaria''), or, rarely, trees (e.g. ''Dendrocnide'', ''Cecropia''). '''[[Leaves]]''' are usually entire and bear [[stipule]]s. Urticating hairs are often present. Urticaceae have usually unisexual '''flowers''' and can be both [[plant sexuality|monoecious]] or [[plant sexuality|dioecious]]. They are [[anemophyly|pollinated by the wind]]. Most disperse their [[pollen]] when the [[stamen]]s are mature and their filaments straighten explosively: a peculiar and conspicuously specialised mechanism. == Genera == {| |- valign=top | *''[[Aboriella]]'' *''[[Achudemia]]'' *''[[Archiboehmeria]]'' *''[[Astrothalamus]]'' *''[[Australina]]'' *''[[Boehmeria]]'' *''[[Cecropia]]'' *''[[Chamabainia]]'' *''[[Coussapoa]]'' *''[[Cypholophus]]'' *''[[Debregeasia]]'' *''[[Dendrocnide]]'' *''[[Didymodoxa]]'' *''[[Discocnide]]'' *''[[Droguetia]]'' *''[[Elatostema]]'' | *''[[Forsskaolea]]'' *''[[Gesnouinia]]'' *''[[Gibbsia]]'' *''[[Girardinia]]'' *''[[Laportea]]'' *''[[Lecanthus]]'' *''[[Leucosyke]]'' *''[[Maoutia]]'' *''[[Meniscogyne]]'' *''[[Myriocarpa]]'' *''[[Nanocnide]]'' *''[[Neodistemon]]'' *''[[Neraudia]]'' *''[[Nothocnide]]'' *''[[Obetia]]'' *''[[Oreocnide]]'' | *''[[Parietaria]]'' *''[[Pellionia]]'' *''[[Petelotiella]]'' *''[[Phenax]]'' *''[[Pilea]]'' *''[[Pipturus]]'' *''[[Poulzolzia]]'' *''[[Procris (genus)|Procris]]'' *''[[Rousselia]]'' *''[[Sarcochlamys]]'' *''[[Sarcopilea]]'' *''[[Soleirolia]]'' *''[[Touchardia]]'' *''[[Urera]]'' *''[[Urtica]]'' - nettle |} == Image gallery == <gallery> Image:PileaCadierei.jpg|''Pilea cadierei'' Image:Pilea pumila2.JPG|''Pilea pumila'' Image:Poisonivy1.jpg|''Dendrocnide sp.''
