A very handsome small tree, and a free flowerer. It and 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 europee^a and 0. rotundi- 

 folia, than by an3' 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,
