890 ARBORETUM AND FRUTICETUM. PART 111. 
Spec. Char., §c. Leaves cordate, apiculated, shining, serrated, and, when young, 
pubescent beneath. Peduncles corymbose. Calyx glabrous inside. Fruit 
warted and bony. (Don’s Mill., ii. p.622.) The flowers are white, slightly 
tinted with pink ; and they appear in April and May. It was introduced in 
1820. The tree is a native of China and Cochin-China ; and grows to the 
height of 15 ft. or 20ft. In the Botanical Register, Dr. Lindley observes 
that P. sinénsis differs from the common pear in having longer and greenish 
branches, and larger, more lucid, and almost evergreen leaves; insipid, 
apple-shaped, warted, very gritty fruit ; and a calyx, the inside of which is 
destitute of the down that is found on all the varieties of the European 
pear. The tree is perfectly hardy, and it is ornamental; but it is worthless 
as a fruit tree. (Bot. Reg., t. 1248.) The tree vegetates very early in spring; 
when it is easily recognised by the deep rich brown of its young leaves and 
shoots. (Hort. Trans., vol. vi. p. 397.) Royle says, this is the only kind of 
pear known in the gardens of India, into which it was introduced from 
China ; and that it more nearly resembles the English baking pear than any 
other. (I//ust., p. 206.)

Spec. Char., Sc. Buds downy. Leaves ovate, coarsely serrated, tomen- 
tose beneath. Flowers many in a corymb. Fruit top-shaped, small, 
yellowish within. (Dec. Prod., ii. p. 634.) Cultivated in the Bollwyller 
Gardens, from the time of J. Bauhin; and, according to Du Hamel, 
named either from the village of Bollwyller, in Alsace, in the neigh- 
bourhood of which it was found in a hedge, as we are informed by 
Dr. Lippold; or after a baron of that name, in whose garden it was first 
cultivated. It is a very distinct variety, with large rough leaves, having 
somewhat the appearance of those of the apple. The fruit is turbinate, 
small, orange yellow, and unfit to eat. The tree produces fewer branches 
than any other species or variety of pear; and these branches are upright, 
thick, and rigid. It has been in cultivation since 1786, having been intro- 
duced by Greffer, gardener to the Earl of Coventry, at Croom, and after- 
wards to the King of Naples. _ There is a fine tree of this species at Ken- 
wood, 26ft. high ; another, of the same height, at White Knights ; and one 
in the Oxford Botanic Garden, 34 ft. high.

Spec. Char.,§c. Branchlets whitely tomentose. Leaves oval, acute, crenated ;

of Suembu, in Upper 
Nepal,; and found 
from an_ elevation 
of nearly 12,000 ft. 
downward to 9000ft., 
and lower. Intro- 
duced into Britain in 
1820. It approaches to P. bollwylleriana; but its leaves are crenated, and 
not serrated; and its flowers are more numerous. The fine large leaves
