Leaves deeply 5-lobed, with sharp 

 irregular teeth; fruit ripening in 

 spring before appearance of leaves. 

 Yields maple sugar. 



Leaves 3 to 5 lobed, finely toothed: 

 reddish fruit ripening in spring or 

 early summer. Yields maple sugar. 



Leaves compound, the leaflets toothed: 

 fruit ripening in early summer and 

 remaining on trees during winter. 



Leaves large, heart-shaped; fruit a long 

 "pod"' filled with flat seeds which are 

 tufted at each end. A better shaped 

 tree than common catalpa (Catalpa 

 bignonioides). 



Leaves mostly clustered at ends of 

 branches, with slightly wavy mar- 

 gins; flowers white with four large 

 bracts resembling petals. Leaves 

 opposite. 



Leaves resembling those of flowering 

 dogwood, but alternate in arrange- 

 ment; white flowers without the four 

 large petallike bracts. 



Leaves doubly-compound, the leaflets 

 with slightly wavy margins; fruit a 

 flat pod a foot or more in length, 

 twisted when dry. Trees with 

 large branching thorns. 



Leaves compound, leaflets with smooth 

 margins; fruit a pod 3 to 4 inches 

 long. Trees with pairs of short 

 thorns at the base of leaves and 

 twigs. Wood heavy and durable in 

 the ground 



Leaves doubly compound, the pointed 

 leaflets with entire margins; fruit a 

 large, woody, wide pod, 6 to 10 inches 

 long, \}o to 2 inches wide containing 

 a greenish jelly, which is poisonous. 

 Trees without thorns. 



Bud scales few, shell of nut thin, husk 

 wing-ridged, with large cavities; nuts 

 elongated with sweet kernel. 



Xut broader than long, without angles, 

 very thin shelled: bitter kernel, husk 

 thin. 



Xut broad, with bitter kernel. 



Buds with many scales (all of the 

 preceding hickories have buds with 

 few scales) ; bark loosening from trees 

 in shaggy strips. 



Leaveslarge; large, angled, thick-shelled 

 nuts with thick husks splitting to the 

 base; bark shaggy as in preceding. 



Leaves large, hairy: buds large, bud- 

 scales many; bark closely furrowed, 

 not separating from the trunk. Xut 

 with thick husk, large, angled, thick- 

 shelled. 



Leaves small, smooth: fruit abruptly 

 tapering at base to thick stem (resem- 

 bling a small fig) ; husk barely split- 

 ting at top end and usually retaining 

 the nut. 



Leaves compound with toothed edges; 

 spherical fruit growing singly or in 

 pairs; bark brown, furrowed. 



Leaves compound, with toothed edges; 

 fruit in hanging clusters of 3 to 5, 

 pointed and elongated, with viscid 

 hairs when young. Velvety cushion 

 just above leaf-scar; bark gray and 

 smooth on young trees. 



Smooth twigs, opposite; leaves com- 

 pound, leaflets toothed or wavy on 

 the margins and paler beneath; seed 

 with a plump, well-rounded body and 

 a wing extending almost entirely 

 from the end and borne in dense 

 clusters. High-ground tree.
