PASTORAL AND AGRICULTURAL BOTANY 



Grape (Vitis). The old-world grape is Vitis vinifera. The muscadine 

 grapes, or southern fox grapes are Vitis rotundifolia, one of the chief 

 varieties of which is the Scuppernong. The northern fox grape (V. 

 labrusca) has given us the Concord, one of the best grapes grown. 



Okra (Hibiscus csculentus). The capsule of this plant is rich in muci- 

 lage, hence, the fruit is a favorite one to thicken soup.

Blueberry (V actinium corymbosum}. Since the discovery that this 

 swamp shrub can be grown in an acid peat, hopes have been raised that 

 superior table fruits may be derived from the large, sweet, wild fruit. 



Cranberry (V actinium macrocarpon). The trailing plant, which yields 

 the cranberry, so much used in the making of a jelly-like sauce, is grown 

 extensively on Cape Cod, in New Jersey and in Michigan.
