bluish green ; fruits bright yellow till they ripen, when they turn shining black 

 in a short time. Tree loaded with yellow and black fruits for many weeks ; 

 very prolific. Said to be very good for sweet preserves." (WerckU.) 



43442 to 43444. Pyrtjs chinensis X communis. Malaceae. 



Hybrid pear. 



Plants grown at the Plant Introduction Field Station, Chico, Calif. Num- 

 bered on October 24, 1916, for convenience in distribution. 



43442. Hybrid pear, P. I. G. No. 6587, tree 3, row 42. Raised by Dr. 

 W. Van Fleet, in 1907, and presented to the Plant Introduction Field 

 Station, December 22, 1909. 



" Fruit large and of attractive pyriform shape, somewhat resembling 

 Bartlett, but with a deep red cheek on yellow ground. Flesh fine 

 grained, tender, and juicy, with but few granules, flavor sweet and 

 pleasant, quality very good. Should make an attractive market pear, 

 It is hoped the usual resistance to oriental pear blight will be shown 

 by this hybrid variety." (Van Fleet.) 



43443. Hybrid pear, from S. P. I. No. 28497, raised by Dr. W. Van 

 Fleet. On account of differences in the fruits this plant and the fol- 

 lowing have been assigned new S. P. I. numbers. 



Mr. J. E. Morrow describes the fruit of this one as follows : " Row 

 27, tree 7, fruit large, long, and pyriform ; rough greenish skin, dotted ; 

 stalk li inches long, set between lips, fleshy at the base; calyx large 

 in shallow basin ; flesh granular, coarse, juicy ; a late pear of excellent 

 size and shape, but very coarse." 



43444. Hybrid pear from S. P. I. No. 28497. Mr. J. E. Morrow describes 

 the fruit as follows : " Row 28, tree 4, in the test orchard. Fruit large 

 size, roundish, oblate; very short neck; skin rough, irregular, dotted; 

 basin broad, deep, and furrowed. Flesh coarse, but sweet and juicy. 

 A pear of promise." 



43445. Pyrtjs calleryana Decaisne. Malaceae. Callery's pear. 



Plants grown at the Plant Introduction Field Station, Chico, Calif. Num- 

 bered on October 24, 1916, for convenience in distribution. 

 From a tree grown from seed introduced by Mr. George Compere, who col- 

 lected it in 1908 in the vicinity of Hongkong, China. The parent tree from 

 which these seedlings came is standing in the yard of Mrs. Lenora Williams, at 

 Oroville, Calif. The plant may be described as follows: This wild Chinese 

 pear is not uncommon in western Hupeh at an altitude of from 1,000 to 1,500 

 meters and is easily recognizable by its comparatively small crenate leaves and 

 small flowers. This pear maintains a vigorous and healthy appearance under 

 the most trying conditions and might prove to be a very desirable blight-resist- 

 ant stock. Also the woolly aphis, which attacks other species of pears, has not 

 been known to touch this species. (Adapted from Compere, Monthly Bulletin, 

 California State Commission of Horticulture, vol. 4, PP- 313-314, and from 

 Rehder, Proceedings of the American Academy of Arts and Sciences, vol. 50, 

 pp. 237-238.) 



" The male parentage of these seedlings is naturally uncertain, as the tree at 

 Oroville might have been cross-pollinated by bees flying from European or other 

 oriental pear trees in the vicinity." (Fairchild.)
