892 ARBORETUM AND FRUVICETUM. PART III. 
Spec. Char., §c. Leaves ovate, acute, crenated, woolly on the under surface. 
Flowers in corymbs. Tube of calyx woolly. Styles glabrous. Wild in 
woods and way sides in Europe. (Dec. Prod., ii. p. 635.) Cultivated in 
gardens, it is wholly, or conjointly with other species or races, the parent 
of innumerable varieties, termed, generally, in England, cultivated apple 
trees; and in France, pommiers doux, or pommiers a couteau. We adopt 
the specific name J/Zalus, to indicate what may be called the actual 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. 
We are aware that objections may be taken to this mode, as deviating from 
the arrangement given by De Candolle, who places the P. acérba as 
the first, and P. Malus, as the second species of this division; but it is so 
utterly impossible to refer the different varieties correctly to the wild forms 
from which they have been obtained, that we consider the priority of 
names as a matter of no sort of consequence. Besides, as we have, as 
usual, only indicated our own deviations from established authorities in 
parentheses, those who differ from us in opinion will find no difficulty in 
recognising the names and descriptions of De Candolle, and of the others 
who have followed in his footsteps.

Description, §c. Leaves ovate, acute, crenated, glabrous even when young. 
Flowers in corymbs. Tube of the calyx glabrous. (Dec. Prod., ii. p. 635.) 
A native of woods and way sides in Europe. This form, according to De 
Candolle, yields many subvarieties with sour fruit, called, in Britain, cider 
apples; and in France, generally, pommiers a cidre.

Description, §c. Leaves ovate, acuminated, serrated, glabrous. Peduncles 
pubescent. Tube of calyx glabrous. Styles woolly at the base; and, as 
appears from Mill. Ic., t. 269., with the styles twice as long as the stamens, 
and the fruit subglobose, yellowish, and austere. (Dec. Prod., ii. p.635.) A 
native of Siberia; introduced in 1758. According to Mr. Knight, some of the 
finest varieties raised by him are from cultivated apples fecundated with the 
blossoms of this tree. The progeny he found formed more hardy trees than any 
other kinds, and that they produced earlier and more highly flavoured fruit.

the length of the petiole. Flowers grouped. Sepals deciduous. (Dec. Prod., 
ii. p.635.) A native of Siberia and Dahuria, and only differing from the 
preceding sort, of which it is, doubtless, a subvariety, in not having a persist- 
ent calyx.
