The following Wild Vetches occur in this region : 



Vicia angustifolia is an annual vine about eighteen inches long 

 with pinnate leaves ending in a tendril as do the other vetches, narrow 

 leaflets and with one or two purple flowers close in the axils of the 

 leaves. Naturalized from Europe m the Atlantic coast states and oc- 

 curring frequently in old fields in many parts of Maryland. Most of 

 the vetches are good for forage. (Figure 10). 



Vicia Americana. A perennial vine two to three feet long; the 

 bluish flowers about three-quarters of an inch long and about seven in 

 each cluster. Occurs in moist ground in the northern states and 

 probably occasionally in Maryland. 



Vicia Caroliniana differs from the last in the white flowers, less 

 than half an inch long and about twelve in each cluster. It is found 

 along river banks mostly west and south of this, and is seen rarely 

 along the Potomac above Washington. 



Vicia Cracca, a perennial with dense, one-sided spikes of purplish 

 flowers, found in the northern states and Europe in dry soil. May be 

 seen rarely in Maryland. 



Tare, Vicia hirsuta, somewhat like the last, but annual, few 

 flowered and hairy, may occur rarely in Maryland. It is a native of 

 Europe.
