A tree 30—60 feet high, erect, straight, generally slender for its height. 

 Imises linear-lanceolate, entire, very slightly mucronate, nearly sessile, gen- 

 «»^lly deciduous, when young of a very light green colour, resembling some- 

 what those of the willow. Spihes of sterile florets near the termination of 

 the last year's wood. Fertile florets solitary in small clusters. Fruit (an 

 acorn) nearly spherical, mucronate, small, sitting in a scaly cup. 



The leaves oi the young plant have generally one tooth or angle, rarely 



'nore, on each side. 



Grows generally in swamps or along tlieir margins; the timber is but little 

 used Willow oak.
