Urticaceae /ɜːrtᵻˈkeɪsiː/, or the nettle faimily, is a faimily o flouerin plants. The faimily name comes frae the genus Urtica (nettles). Urticaceae include a nummer o well-kent an uiseful plants, includin the aforementioned nettles, ramie (Boehmeria nivea), māmaki (Pipturus albidus), an ajlai (Debregeasia saeneb).
The faimily includes approximately 2600 species, grouped intae 54 tae 79 genera accordin tae the database o the Ryal Botanic Gardens, Kew. The lairgest genera are Pilea (500 tae 715 species), Elatostema (300 species), Urtica (80 species), an Cecropia (75 species).
Urticaceae can be foond warldwide, apart frae the polar regions.
APG II system puts Urticaceae in order Rosales, while aulder systems consider it pairt of Urticales, along wi Ulmaceae, Moraceae an Cannabaceae. APG still considers "auld" Urticales a monophyletic group, but does nae recognise it as an order on its awn.
Urticaceae can be shrubs (e.g. Pilea), lianas, yerbs (e.g. Urtica, Parietaria), or, rarely, trees (Dendrocnide, Cecropia).
Leaves are usually entire an bear stipules. Urticatin (stinging) hairs are eften present.
Urticaceae hae usually unisexual flouers an can be baith monoecious or dioecious. They are pollinated bi the wind. Maist disperse their pollen when the stamens are mature an their filaments straighten explosively, a peculiar an conspicuously specialised mechanism.
