The Urticaceae are a family, the nettle family, of flowering plants. The family name comes from the genus Urtica. The Urticaceae include a number of well-known and useful plants, including nettles in the genus Urtica, ramie, māmaki, and ajlai.
Boehmeria is a genus of 47 species of flowering plants in the nettle family Urticaceae. Of the species, 33 are indigenous to the Old World and 14 to the New World; no species is indigenous to both the Old and New Worlds. The species include herbaceous perennials, shrubs and small trees. Although related to the similar-looking species of the stinging nettles of genus Urtica, species of Boehmeria do not have stinging hairs. Because of the similarity in appearance, some species are commonly called "false nettles".

Pouzolzia is a genus of flowering plants in the nettle family. There are about 35 species distributed throughout the tropical world. Most are shrubs, and some are herbs. The genus was named for French botanist and plant collector Pierre Marie Casimir de Pouzolz (1785–1858).
Elatostema is a genus of flowering plants containing approximately 350 known species in the nettle family Urticaceae, native to tropical forest clearings throughout Australasia, Asia and Africa. There may be as many as 1,000 species of this little-known genus, which is susceptible to deforestation and other forms of human exploitation. Some species, for instance the recently discovered E. fengshanense, show unusual adaptations to growing in deep shade in caves. DNA analysis suggests that the three genera Elastostema, Pellionia, and Pilea be grouped together as one.
