Broussonetia papyrifera is a tree to 20 m tall but usually smaller, crooked or leaning, bark yellowish with smooth network of fine ridges, twigs rough textured, gray-hairy, sap milky. 

Leaves alternate, to 20 x 9 cm, rough above, densely velvety hairy below, usually lobed, (similar to Morus alba) very variable, margin toothed. 

Flowers in gray catkins; blooms April-May. 

Fruit red, to 3 cm, fleshy. 

Wetland status: NL. 

Frequency in New York City: Infrequent. 

Origin: S. China, Japan. 

Habitat: Escaped from cultivation into disturbed sites. 

Notes: May become infected by Nectria cinnabarina (Ascomycotina), coral spot canker, that colonizes injured bark or other damaged tissues. Fruiting bodies are small, pinkish warty growths on dead bark or stems. Fusarium solani (Ascomycotina) causes a canker that kills twigs. Roots are sometimes attacked by root knot nematodes Meloidogyne sp. tiny, worm-like parasites that feed on root tissues and cause warty growths on roots (Dirr 1990; Sinclair et al. 1987; Agrios 1988).
