Urticales, order Urticales(noun)
an order of dicotyledonous plants including Moraceae and Urticaceae and Ulmaceae
Urticales is a botanical name for what used to be an order of flowering plants. Before molecular phylogenetics became an important part of plant taxonomy, Urticales was recognized in many, perhaps even most, systems of plant classification, with some variations in circumscription. Among these is the Cronquist system, which placed the order in the subclass Hamamelidae [sic], as comprising : ⁕family Barbeyaceae ⁕family Cannabaceae ⁕family Cecropiaceae ⁕family Moraceae ⁕family Ulmaceae ⁕family Urticaceae In the APG III system the plants belonging to this order, along with four other families, constitute the order Rosales. Cecropiaceae is no longer recognized as separate from Urticaceae. The families Ulmaceae, Cannabaceae, Moraceae, and Urticaceae form a clade that has strong statistical support in phylogenetic analyses of DNA sequences. This clade has been informally called the urticalean rosids.
