IMPORTANT REPRESENTATIVES. In addition to the Mulberry trees, of which 

 Morus alba is cultivated for the rearing of Silk-worms and M. nigra (Fig. 574 B) 

 as a fruit-tree, the genus Ficus deserves special mention. The species occurring 

 farthest north is the Common Fig( 19 ) (Ficus car -ica, Fig. 614), which is endemic to 

 the Mediterranean region, and has been long cultivated. It is a low tree with 

 palmately incised leaves and stipules, which form a cap-like protection to the bud.
