Nut broad, with bitter kernel. 



Buds with many scales (all of the pre- 

 ceding hickories have buds with few- 

 scales), nuts not flanged at joints, 

 shell thick and bony. Bark loosen- 

 ing from trees. 



Difficult to distinguish from shagbark 

 hickory. Twigs are pale orange, 

 while in the preceding they are light 

 red-brown. 



Bud scales many, bark closely furrowed 

 not separating from the trunk. Nut 

 oblong. 



Like preceding in many respects* 

 Nuts not elongated. 



Leaves compound, with toothed edges 

 fruit growing singly or in pairs 

 rounded; bark brown. 



Leaves compound, with toothed edges; 

 fruit in hanging clusters of 3 to 5, 

 pointed and elongated. Velvety 

 cushion just above leaf-scar; bark 

 gray. 



All species of ash are difficult to iden- 

 tify, and mostly require expert 

 knowledge of the fruit or "keys." 

 White ash has a key or fruit with a 

 plump well rounded body and a wing 

 extending almost entirely from the,; 

 end. 



Differs from white ash in having young 

 twigs velvety and wing of seed ex- 

 tending down along sides of seed- 

 body. 



Like the preceding, except twigs are 

 smooth. 



Resembling red ash, but fruits are very 

 much larger, sometimes twice the 

 size. 



Fruits with a flat wide wing, which ex- 

 tends conspicuously down the sides 

 of the seed body. 



Fruits very wide and flat, frequently 

 3-winged. 



Leaves palmately compound; fruit in a 

 knobby husk. " 



Resembling preceding, but fruit in a 

 smooth husk.
