are young plants in the Arnold Arboretum raised from seeds sent from the Agri- 

 cultural Department at Sapporo. 



According to the author's description C. koraiensis Nakai in Tokyo Bot. Mag. 

 XXVII. 191 (1909); in Jour. Coll. Sci. Tokyo, XXXI. 191 {Fl. Kor. II.) (1911) 

 from Korea " Kyongsan: Changdo et monte Phalchoryong," T. Uchiyama (type 

 ex Nakai) and " Ham-gyong: circa SomuietQuensan," T. Nakai (co-type ex Nakai), 

 has larger black fruits ("vnlgo 1.3 cm. longa"), the pedicels of which are 2.5-3 

 cm. long. The leaves are described as " 5-11 cm. longis, 2-7 cm. latis . . . praeter 

 basi argute serratis, serratulis apice incurvis." Unfortunately Nakai does not 

 clearly describe the stone. His phrase " endocarpio osseo integro " seems to indi- 

 cate that the stones are smooth. In that case C. koraiensis would be closely re- 

 lated to C. Bungeana Blume, but on account of the serration of the leaves I am 

 incUned to beheve that Nakai's species may be the same as C. jessoensis. Not hav- 

 ing seen a specimen, I cannot decide the question. Nakai compares his species 

 with C. occidentalis Linnaeus from North America, which differs in many respects, 

 while Koidzumi says of his C.jessoensis: " Species Celtis Tournefortii Lam. affinis." 

 Lamarck's species from southern Europe and western Asia differs widely in its 

 bluish green leaves, its yellowish red fruits, in its almost smooth stones, etc. The 

 nearest relative to either C. jessoensis or C. koraiensis is C. cerasifera Schneider
