1206. O'rnus europa. 
A very handsome small tree, and a free flowerer. It und also the following 
species, and probably all those of both the genera Fraxinus and O’rnus, ex- 
travasate sap, which, when it becomes concrete, is mild and mucilaginous. 
This sap is produced in more abundance by O’rnus europe‘a and O. rotundi- 
folia, than by any other species; collected from these trees, it forms an 
article of commerce under the name of manna, which is chiefly obtained from 
Calabria and Sicily, where the tree abounds.
