Male an female flouer o Urtica

APG II system puts Urticaceae in order Rosales, while aulder seestems consider it pairt of Urticales, along wi Ulmaceae, Moraceae an Cannabaceae. APG still considers "auld" Urticales a monophyletic group, but daes 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).

Leafs are uisually enteer an beir stipules. Urticatin (stingin) hairs are eften present.

Urticaceae hae usually unisexual flouers an can be baith monoecious or dioecious. Thay are pollinatit bi the wind. Maist disperse their pollen whan the stamens are matur an their filaments straichten explosively, a peculiar an conspicuously specialised mechanism.
