Pecan
Carya illinoinensis
Juglandaceae

Leaves are alternate, deciduous and pinnately compound with up to 17 sickle to lance-shaped leaflets. Twigs are stout and gray-brown with light brown hairy buds with valvate scales. The pecan nut is known world wide. Form is up to 45 m (150 ft) in height or sometimes taller (the largest of the native hickories). Pecan originated from the central U.S. but has naturalized in the southern U.S. and is intolerant of shade. The heavy wood is used for handles and pulpwood.
