FRAXINUS (Linn.) 
Male flowers with a minute 3 or 4-toothed calyx or that part wholly want- 
ing. Corolla none ; stamens 2 to 4. Pistillate flowers equally imper- 
fect. Ovary superior, ovate, compressed, 2-celled, the cells each with

The Ashes are trees of the northern hemisphere, and almost entirely con- 
fined to Europe and North America. The leaves are opposite and pin- 
nate; the flowers dioecious and paniculate, rarely racemose. The leaves 
of some of the species in warm climates exude the saccharine substance 
called manna. The wood of several species of this genus is much 
esteemed for its strength and elasticity.
