- Cannabaceae (hemp family)
- Moraceae (mulberry family)
- Ulmaceae (elm family)
- Urticaceae (nettle family)
These range from small herbaceous plants to large trees, blooming from the late spring to early fall. The Urticales were placed within the subclass Hamamelididae, variously considered close relatives of other orders such as the Hamamelidales, Juglandales, Leitneriales , Fagales, Casuarinales , Myricales, and Daphniphyllales . Phylogenetic systems, however, generally subsume the order into the Rosales.
