cultiyated of all ligneous plants; the apple and the pear being highly esteemed 

 fruits, both in the temperate and transition zones of both hemispheres. These, 

 and all the species of the genus, are propagated by grafting on the wild varie- 

 ties oi' each division. We have before stated the price of the grafted fruit 

 trees which belong to i?osaceae to be, about London, from 1*, to Is. Qd. each 

 for dwarfs, and from 2s. 6d. to 5s. each for standards; at Bollwyller, francs may 

 be substituted for shillings ; and at New York, cents for halfpence ; the Ame- 

 rican cent being about equal to the English halfpenny, or the French sous, and, 

 of course, worth 5 French centimes.

Varieties. De Candolle mentions two forms of the wild species, compara- 

 tively permanent ; to which we have added several others, the result of cul- 

 tivation, and which are more or less accidental or temporary. To these we 

 might have subjoined a class of wild pears with hoary leaves, such as P. 

 nivalis, P. salicifolia, &c, which we consider as varieties, or races, though 

 commonly treated as species ; but we have preferred giving them afterwards 

 as distinct sorts. 

 It P. c. 1 A^chras Wallr. Sched., p. 213. — Spiny leaves ; woolly when young, 

 but afterwards glabrous; the disk ovate, acuminate, entire; the 

 petiole long. Tube of the calyx woolly when young, afterwards 

 becoming glabrous. Pome with its basal part long. 

 If P. c. 2 Pyraster Wallr. Sched., p. 2 14., Gaertn. Fr., t. 87. f. 2. — Spiny. 

 Leaves roundish, acute, sharply serrated, glabrous even when young. 

 Tube of the calyx, while young, glabrous. Pome rounded at the base. 

 ^ P. c. Sfoliis variegdtis has variegated leaves. 

 It P. c. ^fructu variegato has the skin of the fruit variegated with yellow 



and white. 

 1 P. c. 5 sanguinolenta, the sanguinole Pear, has the flesh of the fruit red, 

 or reddish; and, though small and gritty, is not bad to eat when ripe. 

 t P. c. QJlore pleno ; Poire de l'Armenie Bon.Jard., p. 43. ; has double 



flowers. 

 It P. c. 7 jasjrida ; Bon Chretien a Bois jaspe Bon Jard., edit. 1836, 



p. 424. ; has the bark of the wood striped with yellow. 

 ¥ P. c. 8 sativa Dec. — Without spines. This is the cultivated variety, of 

 which there are very numerous subvarieties in gardens. For these 

 De Candolle refers us to Miller's Dictionary, and to Du Hamel's 

 Dei Arbrcs Fruitiers ; but, at the present time, by far the most com- 

 plete collection in the world, of cultivated pears, is in the garden of 

 the London Horticultural Society; and they are described in the 

 Fnut Catalogue (edit. 1831) of that body. From this catalogue 

 Mr. Thompson has made for us the following selection of sorts 

 which arc at once deserving of culture as ornamental trees, and as 

 producing fruit of first-rate excellence. 

 Beurre Diet. Leaves large, and flowers very large. A hardy tree, some- 

 what litstigiate in its shape; a great bearer, and deserving of exten-
