Narrative

The name 'Guar Li' means 'Water Pear', alluding to the soft, very juicy character of the flesh. The fruit is small to medium in size, oblate, yellowish with a red cheek. The calyx is persistent, and the stem of medium length in some specimens, and long in others. The flesh is soft, juicy, and of fair quality in some strains and good in others. The leaves, at least of the strains which I studied, show the typical form and margins of P. ussuriensis. Unfortunately, I did not obtain scionwood of this variety. We have a large number of seedlings of it, and these are very vigorous growers, and show a very marked degree of resistance to the pear blight. This is a very promising variety for breeding purposes and also as a stock for other pears. On my next trip to China, I shall obtain scionwood of this variety. -- F.C. Reimer. 1919. Report of a trip to the Orient to collect and study Oriental pears.
