892 ARBORETUM AND FRUTICETUM. PART IJI. 



Spec. Char., ^c. Leaves ovate, acute, crenated, woolly on the under surface. 

 Flowers in corymbs. Tube of calyx v.'oolly. 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 ponimiers a couteau. We adopt 

 the specific name J/alus, 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. il/alus, 

 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. acerba as 

 the first, and P. J/alus, 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 

 |)arentheses, 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. 63.5.) 

 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, Sfc. Leaves ovate, acuminated, serrated, glabrous. Peduncles 

 |)ubescent. Tube of calyx glabrous. Styles woolly at the base; and, as 

 appears from 2Iil!. 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 175S. 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.

 preceding sort, of which it is, doubtless, a subvariety, in not having a persist- 

 ent calyx.
