          about one inch in diameter are allowed by the Chinese to hang on the 
tree till they are black and dead ripe, when they are pleasantly sweet 
and are made into jellies. This species is said by some to be the stock 
upon which the native gardeners of Yunnan graft their sand pears.

55805. PYRUS SEROTINA X COMMUNIS. Hybrid Pear. Originated by 
the late Dr. Walter Van Fleet at Little Silver, N. J., and grown at the 
Plant Introduction Garden, Chico, California. It is a hybrid between 
the Golden Russet, an oriental pear, and one of the common European 
types. It is medium to large, roundish, with golden and speckled skin 
of deep russet hue. The flesh is whitish, sweet, slightly subacid, 
granular, and surrounds a medium core with a few large seeds. It is 
practically free from grit cells. The appearance of this pear is handsome 
and when properly ripened it makes a fine baking and preserving 
fruit. The trees are large and vigorous and bear heavy crops.

55998. PYRUS sp. Pear. From Yunnan, China. Collected by J. F. Rock, 
Agricultural Explorer. This hardy tree, which grows 15 to 20 feet high, 
is found on the Lashipa Plain at an altitude of 10,000 feet. It has 
very tough branches, and bears large numbers of fruits which are the 
size of marbles, and yellow, acrid, and unpalatable. Sometimes used 
by the natives of Yunnan as a stock plant for cultivated pears.

NOTE: The various species and varieties of Pyrus introduced from Yunnan through Agricultural Explorer J. F. Rock have been secured for 
trial primarily as stocks upon which to graft the pears already cultivated  
in the United States. Some of them are described by Mr. Rock 
as horticultural forms from gardens and orchards in Yunnan; in view of 
the fact that the plants here listed have been grown from seeds, not 
by budding or grafting, the fruits produced of these domesticated 
forms will not, in most instances, agree with Mr. Rock' s descriptions.

56000. PYRUS sp. Pear. From Yunnan, China. Collected by J. F. 
Rock, Agricultural Explorer. A wild pear tree 20 feet high found 
on the Likiang Plain near the village of Lasadje. The fruits of this 
species are smaller than marbles, yellow, spotted and at first acrid, 
but perfectly sweet and black when ripe.

56008. PYRUS sp. Pear. From Yunnan, China. Collected by J. F. Rock, 
Agricultural Explorer. A tree reaching 45 feet in height and having 
long drooping branches. Although it is a domesticated species, called 
ho pa li by the Chinese, it is not grown in orchards, but individual 
trees can be found here and there, especially east of Tali Lake. The 
oval-oblong pears are fiery red with a yellowish base, very juicy and
