N. Grandidentata, Mich. arb. for. 2. p. 252. 
A large tree 60 — L 80 feet in height, 2—4 in diameter. Leaves large, 
ovate and oval-lanceolate, irregularly and acutely toothed, sometimes only 
on one margin, pubescent underneath, particularly along the nerves, the lower 
or older leaves distinctly cordate. The sterile florets I have never noticed. 
Fertile solitary, axillary. Fruit oval or ovate, large, dark blue. 
Grows in deep swamps. A truly aquatic tree. I have seen it flourishing 
in mill-ponds and “back waters,” where the water has been maintained for 
half a century from 5 to 8 feet deep. I believe the N. Aquatica grows also 
in similar situations. The root of this tree is as light as the bark of the cork 
tree, (Quercus suber) but wants elasticity'. 
Flowers April — May.
