ters. As the plants are dioecious, only a portion, those with pistils, 

 bear the fruit. There are handsome variegated forms with white or yel- 

 low stripes, dots, and blotches to the leaves, arranged in many patterns 

 and giving rise to many varietal names. [Twig cuttings ; seeds.] 



Vibdrnum. The Viburnums form a large group, 80 species, of 

 opposite simple-leaved ornamental shrubs. A number are in cultivation 

 and several are very beautiful in foliage, flowers, and fruit. Some have

bright colored drupes which remain through the winter ; they have, in 

 most species, a decidedly flattened stone. The Snowball group are like 

 the Hydrangeas (see p. 192) in that the blossoms have become enlarged 

 and sterile. The Hydrangeas have white, pink, purple, or bright blue 

 flowers ; while the Viburnums have only white or creamy flowers. The 

 Viburnums bloom earlier, all being in bloom in May ; while the Hydran- 

 geas do not begin to bloom before June and some species continue bloom- 

 ing through July and August. So Viburnums are spring-blooming and 

 Hydrangeas are summer-blooming. The small fertile flowers, if closely 

 examined, will show plain differences. The Hydrangeas have 4 to 5 

 separate petals to the corolla, while the Viburnums have bell-shaped 

 5-lobed corollas. The Hydrangeas have 8 to 10 long stamens, the Vi- 

 burnums 5 short ones. [Seeds ; twig cuttings, under glass. ]
