Narrative

Original seedlot collected by Frank N. Meyer. Received March 2, 1915. Quoted notes by Mr. Meyer in USDA Plant Inventory No. 42. 'Pyrus ussuriensis Maxim. No. 2157a. Near Tshenyatau (near Titao), Kansu, China. December 1, 1914. A species of wild pear, growing to be a large tree,with a wide-spreading,dense head of branches. Bark of dark color and in the main trunk even blackish and deeply furrowed in old specimens. Young branches often ferociously spiny and especially so in suckers. Leaves small and with much shorter peduncles than in Pyrus chinensis. Fruits globose, flattened. Calyx persistent, peduncle generally short; much variation exists as regards size, but the fruits of this species of pear are generally small; the flesh is also acri and often quite hard, though some of the larger ones are edible after having been frozen. This pear is not found in the warm valleys, but it thrives best at altitudes of about 8,000 ft. in company with such hardy trees and shrubs as Picea obovata, Populus tremula, Malus baccata, Hippophae rhamnoides, Syringa amurensis, Rhamnus dahurica, Sorbaria sorbifolia, and others. This pear has apparently given rise to some locally cultivated forms bearing small, sour fruits, which are juicy, however, and melting, and not hard and gritty, like the poorer strains of P. chinensis. Of undoubted value as a stock for pears in cold sections and as a factor in breeding experiments in trying to extend successful pear culture farthernorthward.'
