122 MARYLAND AGRICULTURAL EXPERIMENT STATION 



Hog-peanut j Falcata comosa. A slender, climbing vine with tri- 

 foliate, bean-like leaves and thin, flat pods with small seeds above, but 

 much larger seeds borne underground on the lower branches. In 

 moist open woods, especially on the rocky banks of streams ; common 

 west of the Bay, and in most of the Eastern States, not common on 

 the Eastern Shore. It adds some to woodland pastures, tne under- 

 ground seeds being eaten by hogs and the vines by other stock. (Plate 

 I. Figure 30). 



Hog-peanut, Falcata Pitcheri. Similar to the other hog-peanut but 

 larger and rougher; the vine covered with stiff hairs. Common west 

 and north. One specimen found at Greenmount, Maryland. 



Ground-nut, Apios tuberosa. A climbing vine with large clusters 

 of large, handsome, brownish, fragrant flowers and tuberous roots, 

 found in moist ground in old fields and edges of woods all over the 

 eastern United States. It is seen frequently in the counties of Mary- 

 land bordering the Bay and in a few other places. The fleshy roots 

 were used for food by the Indians and others. The vine is valuable 

 for ornamental purposes; it is eaten by stock and the tubers by hogs. 

 (Plate I. Figure 31). 



Butterfly-pea, Bradburya Virginiana. A perennial vine with tri- 

 foliate leaves and very large purplish flowers. Found frequently in the 

 sandy lands of the lower part of the Peninsula in Maryland and more 

 commonly in the south. Verv ornamental, and adds to wild pasture. 

 (Plate I. Figure 28). 



Buttevfly-pea, Clitoria Mariana. A vine-like herb, one to three feet 

 high, differing from Bradburya mainly in less twining stem and 

 shorter pods not thickened at the edges. In dry soil in the Southern 

 States and north to New Jersey and extending inland in Maryland 

 to Frederick County. It is said to be nutritious to stock. (Plate 1. Fig- 

 ure 29). 



Black locust, Robinia Pseudacacia, is a well-known tree with a 

 maximum height of eighty feet, with pinnate leaves, a pair of stout 

 spines at the base of each, and having clusters of large, white, fra- 

 grant flowers. It is a native of the Mississippi Valley, but extensively 

 naturalized along our fence-rows and in waste lands, often in quite 

 moist places, but then not bearing tubercles so abundantly. Found 

 especially in central Maryland, but is not so common in the southern 

 part of the Eastern Shore. The wood is strong and durable, and is 

 commonly used for posts, but also for finer woodwork. Perfume has 

 been made from the very fragrant flowers, which are also rich in 

 honey. 



Honey locust, Gleditsia triacanthos. A large tree with much di- 

 vided leaves, and long, flat pods; usually with branched thorns, but 

 often thornless. Native of the eastern Mississippi Valley, but natur- 

 alized in many places in cultivated lands in Maryland and other 

 States eastward. The hard wood is of value. The pulp of the pods is 

 sweet when fresh, hence the name. The thornless kind is best for or- 

 nament. Stock eat the pods and young growth.
