dish brown, meat quite solid and very sweet, size often as large as small 

 lien's eggs. Trees of thrifty growth, assuming remarkably large dimen- 

 sions for jujubes, trunks being seen li feet in diameter. The trees are 

 almost spineless when old and sucker but very little. Apparently not at- 

 tacked by ' bunch disease,' although infected wild bushes were seen in 

 close proximity. Propagated by suckers exclusively. The wood of this 

 jujube is extensively used in the manufacture of combs and in all sorts 

 of turnery work, this industry having its seat in and around the village 

 of Tafutze. Chinese name Chin tsao and Fei tsao, meaning ' golden 

 jujube ' and ' fat jujube.' " 

 Cuttings. 



40507. Ulmus pumila L. Ulmacese. Elm. 

 "(No. 1253. Peking, China. February 23, 1915.) Yar. pendula. A 



weeping variety of the very drought-resistant North Chinese elm, not 

 growing apparently to very large dimensions. Of value as a character- 

 istic ornamental tree, especially fit for cemeteries and for parks in 

 cold and semiarid sections. Shows up particularly well when planted 

 on embankments alongside water expanses. Chinese name Lung chao 

 yii slut, meaning ' dragon's-claw elm tree.' Obtained from the Botanical 

 Garden at Peking."

 pumila), see Plate II. 



40508. Castanea mollissima Plume. Fagacese. Chestnut. 



"(No. 2179a. Sianfu, Shensi, China. January 25, 1915.) A large- 

 fruited variety of Chinese chestnut, coming from Yatzeko, south of 

 Sianfu, railed Qui li tzu, meaning 'superior chestnut.' Tins variety 

 is propagated by grafting. It seems on the whole somewhat more re- 

 sistant to the bark disease (Endothia parasitica) than the ordinary 

 strain of Chinese chestnut." 



40509. Citrus sp Rutacese. 



"(No. 2180a. Lanchowfu, Kansu, China. December 30, 1914.) A pe- 

 culiar citrus fruit, of medium-large size, somewhat flattened, skin loose. 

 wrinkled, and warty, of dark-orange color. Segments separating easily; 

 flesh bitterish, but not disagreeably so. Said to come from Szechwan, 

 which also means southern Shensi to ordinary people. Crowing where 

 tangerines also thrive. Chinese name Wan t:C(."
