Urticales

Clades: Rosales; Fabanae; Angiospermae; Plants.TaxonomyUrticales was recognized in most classifications. Cronquist placed the order in the subclass Hamamelidae comprising:
Barbeyaceae, Cannabaceae, Cecropiaceae, Moraceae, Ulmaceae, Urticaceae
The Apg3 classification places these families in Rosalesorder Rosales. Cecropiaceae is no longer recognized as separate from Urticaceae.
The families Ulmaceae, Cannabaceae, Moraceae, and Urticaceae form a phylogenetic clade, called the Urticalean rosids: Celtidaceae, Cannabaceae, Cecropiaceae, Moraceae, Ulmaceae, Urticaceae. Urticalean rosids are derived out of a lineage including Barbeyaceae, Dirachmaceae, Elaegnaceae, and Rhamnaceae, with Rosaceae less closely related. They have as characteristics:
- dense gray tomentum comprising curly unicellular trichomes on abaxial leaf surfaces.
- reduced stamen count to one whorl or less.
- inconspicuous flowers with up to five stamens
- 2 carpels.
- unilocular ovary with single apical ovule.
- urticoid teeth upon leaves.
- developed prophyllar buds between paired inflorescencesBotany: wide range, deciduous or evergreen trees, vines, shrubs, annuals, some succulents; leaves variable, brochidodromous or palmately pinnate venation, often lobing or compounding in the leaf blade.
Moraceae, Urticacae and Cecropiaceae, produce latex.
