In woods and hedges ; especially on hills in limestone countries. 



Tree. April, May. 



One of our tallest, most graceful trees, with a smooth grey bark, 

 and large, coal-black, rather downy buds. Wood tough, whitish. 

 Leaves stalked, of 5 or 6 pair, with an odd one, of ovate-lan- 

 ceolate, acute, nearly sessile, opposite leaflets, whose main rib 

 is fringed beneath; their common stalk channelled and bordered. 

 Panicles from lateral buds, below the leaf-buds, drooping, many- 

 flowered. Flowers small, brown, consisting only of a pistil, with 

 (generally) one short stamen at each side. Very rarely there 

 are flowers with stamens only. Capsules with a fiat leaf-like 

 termination, an inch long, and generally of 2 cells, with an ob- 

 long seed in each, glittering with rusty meal^ like an almond, 

 but bitter and nauseous. 



The Weeping Ash, a variety with drooping branches, is propa- 

 gated by grafting only. 



2. F. heterophylla. Simple-leaved Ash. 



Leaves both simple and compound, with tooth-like serra- 

 tures.
