35301. Zelkova serrata (Thunb.) Makino. 

 {Zelkova acuminata Planch.) 



"(No. 1796a, Mukden, Manchuria, Mar. 11, 1913.) A very useful timber 

 tret from Japan, now being experimented with by the Japanese in southern

35303. JuGLANS MANDSHURiCA Maxim. Manchurian walnut. 

 "(No. 1798a, Mukden, Manchuria, Mar. 11, 1913.) The Manchurian walnut, 



a stately timber tree, occurring in Manchuria and Japan. It is very sensitive 

 to late frosts and on that account has proved to be a tree difficult to grow away 

 from its native countries. ' ' 



35304. Pyrus ussuriensis Maxim. Pear. 

 "(No. 1799a, Harbin, Manchuria, Mar. 1, 1913.) A wild pear occurring in 



many places in eastern Siberia, Manchuria, and North China. This pear 

 is probably the hardiest on the globe, withstanding temperatures where all 

 other pears succumb. In central Siberia and in St. Petersburg this is the 

 only pear that survives the winters unprotected. The fruits are rather small 

 and inedible except after haAdng been frozen or cooked, but the remark- 

 able hardiness of this pear puts it in the front rank as a factor in breed- 

 ing experiments with the aim to create hardier pears. This pear possesses 

 a persistent calyx and has a very short peduncle, while the true Pyrus 

 sinensis has a very long peduncle and the calyx drops off perfectly as soon as 

 the fruit is formed. There are also several important differences between the 

 two in so far as characteristics of bark, foliage, and general looks are concerned. 

 See notes under S. P. I. No. 20336."

35306. ViTis AMURENSis X RiPARiA. Grape. 

 "(No. 1801a, Kozlof, Tambof Government, Russia, Jan. 21, 1913.) A few 



dried fruits of a hybrid grape which is perfectly hardy in central Russia. The 

 berries are small, but possess a good flavor, and they probably can be much 

 improved by further selection. This hybrid was obtained by Mr. I. V. Mijurin, 

 plant breeder at Kozlof, Russia."
