8o RUE FAMILY 



Morus alba L i n n e 1753 White or Russian Mulberry 



Low tret", 20-40 ft. high, J^-2 ft. diam. ; hark light yellowish-gray, 



more or less deeply furrowed ; leaves ovate to nearly round, often 3-5- 

 lobed, edge coarsely serrate, tip rounded or pointed, base usually heart- 

 shaped, smooth and somewhat shining on both faces, 8-12 cm. long, 7-10 

 cm. wide, petioles sparsely hairy, 2-4 cm. long; staminate catkins 1-2 cm. 

 long, pistillate catkins elliptic to globose. 1 cm. long ; fruit oblong to 

 elliptic, white to pink, 1^-2 cm. long: alba, white, in reference to the 

 fruit. 



Cultivated; introduced from Europe for feeding silkworms. The 

 fruit is much more insipid than in the red mulberry, and the tree is 

 hardly desirable because of the litter of fallen berries. It is of some 

 value in cherry orchards in drawing birds from the cherries, but it is 

 scarcely hardy.
