Deciduous trees or shrubs. Leaves alternate, stalked undivided or 3 

 lobed, rarely 5 lobed, serrate, 3 nerved at the base. Flowers dioecious or 

 monoecious, apetalous. Staminate in cylindric or globose catkins, calyx 4 

 parted; stamens 4, exserted at maturity. Pistillate flowers in a globose 

 head, composed of the compact, persistent, villose or tomentose perianth 

 and bracts; perianth tubular, 3-4 toothed; ovary included, stalked; style, 

 single, filiform, stigmatic to the base or nearly so. At maturity the 

 fruiting head is globular, consisting of numerous 1-seeded, orange-red, 

 drupelets. 



3 species in E. Asia and the Pacific Islands; 2 in China. 



Broussonetia papyrifera (L.) L. Heritier. 

 (Morus papyrifera Linnaeus.) 



Tree up to J 6 m. high, with broad, round-headed crown. Bark dark 

 gray and smooth. In cultivation, more commonly a vigorous shrub with 

 stout, spreading, pubescent branches. Leaves 7-20 cm. long with stalk 

 2.5—8 cm. long, coarsely toothed, somewhat oblique and cordate at the base, 

 acuminate, often deeply 3 or 5 lobed, rough and dull green above, 

 pubescent below. Mature fruiting head about 15-20 mm. across, brick red- 

 Native of China, introduced into Japan, and to Europe in the 18th 

 century. (Chihli, Szechuan, Hupeh, Yunnan and Formosa). 



The bark of Broussonetia is used for paper making. Authorities are 

 inclined to believe that the use of paper mulberry fibers for paper, ante- 

 dated the use of the pith from the bamboo. 



Broussonetia kaempferi Siebold. 



Is known only as a shrub 3 to 5 meters high. It has small, pubescent,, 

 short-petioled leaves and very small fruits.
