Gymnocladus dioicus. the limbs, stout branchlets like the 

 ailantus, and leaves which are unequally twice-com- 

 pound ; the leaflets are

 whole spray is from 

 two to three feet long ; the leaflets are without teeth, 

 and are dull, dark green. The brown, curved pods 

 are two inches broad, and from six to ten inches long; 

 they contain hard, gray seeds half an inch in diame-
