Nut broad, with bitter kernel. 



4* 



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 difficiilt 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 

 oftheseedb9dy. 



Fruits very wide and flat, frequently 

 3-winged. 



Leaves palmately compound; fruit in a 

 knobby husk.
