Juglans nigra. Judlandaceae. Large, pinnately compound leaves with 8-22 leaflets. Terminal leaflet absent or poorly developed (vs ajuga so cinerea--White Walnut or Butternut) that has developed a terminal leaflet. "Monkey face" leaf scars and twigs have chambered pith (Like a ladder), chocolate colored in Butternut but but lighter color in BW. BW has darker bark and BN bark ridges look like someone smoothed off the tops with a knife. BW but is round. BN nut is mioegg-shaped. Both species produce jug lone--a chemical in the roots that kills germinating seedlings. Yellow dye from roots. Walnuts you buy in the store are English walnuts which are less bitter than BW.

Juglans nigra, the eastern black walnut, a species of flowering tree in the walnut family, Juglandaceae, is native to eastern North America. It grows mostly in riparian zones, from southern Ontario, west to southeast South Dakota, south to Georgia, northern Florida and southwest to central Texas. Isolated wild trees in the upper Ottawa Valley may be an isolated native population or may have derived from planted trees.
