Hickories are much more restricted in distribution than are the maples or even the ash and with only two or three exceptions are found only in the south-eastern quadrant of North America. Among the common species of hickory, only the shagbark hickory and the bitternut hickory are found in Canada. You should contrast the leaves of the ash and hickory. The hickory stalk varies from 15 to 25 cm, the leaflets are widest in the middle and pointed at both ends.
Hickories produce edible nuts.
Hickory are considered to be a small to medium sized tree, growing to about 25 m in height with a 60 cm trunk. They are relatively long lived trees often attaining 200 years. You can find more pictures and information on the shagbark hickory here.
