ARBORETUM ET FRUTICETUM BRITANNICUM. 



generally, in England, cultivated apple trees; and in France, pommiers doux, 

 or pommiers ii couteau. We adopt the specific name ilfalus, to mdicate 

 what may be called the normal form, for the sake of convenience, though many 

 of the cultivated varieties are derived not only from the wild apple, or crab, 

 of Europe, but from the crabs of Siberia. We shall designate these crabs as 

 varieties of P. ilfalus, and afterwards make a selection from the cultivated 

 sorts, of such as we think suitable for being planted for their timber, or as 

 ornamental trees.
