B. Leaves opposite or in pairs. 



a. Maples. Eough-barked trees, with five-lobed, notched 



or toothed leaves, and a peculiarly shaped winged 

 twin-fruit, which is so persistent that it may serve 

 in most cases to identify the tree (Fig. 96, D). 



b. Catalpa or Indian Bean. Leaves large, entire (occa- 



sionally three-lobed) ; flowers in large clusters, very 

 showy; fruit a long (twelve inches and more) 

 brown pod, resembling that of the bean (Fig. 96, (7). 



II. Leaves compound, or made up of several leaflets. 



A. Leaf feather-shaped, the leaflets arranged on two sides of 

 a straight stem (Fig. 97, A). 



1. Leaves alternate. 



a. The edge of the leaflets entire, i.e., not toothed. 



Locusts (Fig. 97, A and B). Of these, the honey 

 locust has large thorns and broad brown pods six 

 to ten inches long ; and the Hack locust, or Robinia, 

 has practically no thorns, and small pods two to 

 three inches in length. 



b. The edge of the leaflets toothed. 



Walnuts and Hickories, including Pecan. In the 

 walnut, black walnut, and white walnut, or butter- 

 nut, there are usually thirteen to twenty-three leaf- 

 lets to one leaf and the husk of the nut does not 

 split open along definite lines ; in the hickories, 

 including the pecan, the husk opens along well- 

 defined lines and the number of leaflets varies 

 usually from five to nine, being nine to fifteen only 

 in the pecan and water hickory (Fig. 97, C and D).
