Urticales is 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.

荨麻目（学名Urticales），是被子植物门、双子叶植物纲植物，为草本或木本。 叶多互生，常有托叶。 花小，两性或单性，辐射对称；单被或无被；雄蕊少数 与花被对生，稀多数；子房上位，2～1室，胚珠2～1。

荨麻目植物包括许多有经济价值的品种，如 榕树 、 构树 、 榆树 、 大麻 、 苎麻 等，其中也有许多具有毒性，如 箭毒木 的树汁见血封喉，大麻叶也可以作为麻醉毒品。 也有绿化树种如 榕树 、 构树 等，药用植物也很多， 忽布 （啤酒花）是酿造 啤酒 的必需原料。

荨麻目 urticales. 花单性、两性或杂性，小而整齐，常有4-5枚花被片，通常雄蕊与花被片同数并与其对生，有1-2心皮，但子房通常单室而内含1枚胚珠，果实为坚果、核果、瘦果或翅果，含1枚种子，胚占据整个种子，直伸或弯曲，为肉质或油质内胚乳所包。

The Urticales constitute a group of plants with surprising diversity and confusing complexity, especially in the Moraceae round which family the present paper is centred. Main trends in the differentiation of the growth habit, flower, fruit, and inflorescence are sketched and as far as possible connected to distribution, pollination, and dispersal.

The Urticales constitute a distinct order, the circumscription of which has hardly changed since about 1850. It comprises the Ulmaceae, Moraceae, Urticaceae, and Cannabaceae. A few minor unigeneric families have been inserted in the Urticales: Theligonaceae, Barbeyaceae, and

The Urticales comprise five families: Rhoipteleaceae, Ulmaceae, Eucommia-ceae, Moraceae and Urticaceae.

There are about 1,000 species of trees and shrubs in this family. They are found in tropical and subtropical regions and contain a milky latex. The plants in this family have alternate leaves and small, petalless male or female flowers. Many of the plants in this family have fruit that is edible.

Ulmaceae are trees or shrubs, often with mucilage, evergreen or deciduous. Leaves of Ulmaceae are simple, stipulate, distichous, often with asymmetrical blades; stipules caducuous. Flowers of Ulmaceae is minute, unisexual or rarely polygamous, solitary or in cymose clusters.
