generally, in England, cultivated apple trees; and in France, pommiers doux, 
or pommiers 2 couteau. We adopt the specific name Malus, to indicate 
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. Malus, 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.
