VIBURNUM CASSINOIDES Linnaeus 

 Withe-Rod 



The Withe-Rod, fig. 68, is an erect shrub with a wide- 

 spreading top, which grows to a height of 4 to 8 feet and is 

 more or less scurfy on the branchlets. The leaves are elliptic 

 to oval or oblong but variable in size as well as shape, measur- 

 ing 1 1/2 to nearly 4 inches long by ^ to 2]/^ inches wide, and 

 they lack stipules. The blades are acute to short-acute at the 

 tip, narrowed or rounded at the base, and irregularly round- 

 toothed to entire on the margins. The leaf surface is scurfy 

 spotted above and below when young but soon becomes smooth 

 or nearly so above. The petioles are usually less than ]/^ inch 

 long, flat and channeled above, and scurfy. 



The white flowers, which appear in June, are produced in 

 gland-bearing cymes up to 3 inches wide. There are usually 

 about 5 sterile flowers in each cyme. The fruit, which matures 

 in September and October, is black, bloom covered, globose to 

 slightly oblong, and more than % inch long. This fruit con- 

 tains a broadly oval, lens-shaped stone, 1 surface of which is 

 marked with a faint rib, and the other surface with a wide 

 groove.
