 without exact locahty, 1842, P. von Siebold (co-type, ex Herb. Zuccarini; flowers and 

 fruits); without locality and collector (ex Herb. Lugd. Bat.; flowers and leaves). 



Siebold & Zuccarini in the original description describe the leaves as " e basi cor- 

 data V. rotunda subobliqua," and I cannot see that Winkler's var. cordifolia repre- 

 sents even a good form, and it is the same with var. pleioneura, as nearly every 

 specimen before me has leaves of both these varieties. A picture of this tree will 

 be found under No. x203 of the collection of V/ilson's Japanese photographs. 1 can 

 maintain only the following variety: 



Carpinus japonica, var. caudata Winkler in Bot. Jahrb. L. Suppl. 488 (1914). 

 A typo recedit fohis lanceolato-oblongis longius caudato-acuminatis grossius 

 serratis. 



JAPAN. Hondo: prov. Shmano, Mt. Ontake, August 1905, U. Faurie (No. 

 6641; fruits). 



This may be only a form and needs further observation. 



Maximowicz (in Bull. Acad. Sci. St. Petersbourg, XXVII. 533 [1882]) mentions 

 a C. japonica, var., " foliis paulo latioribus basi saepe distincte oblique cordatis, 

 ligula non semper a margine bracteae libera, saepius basi cum ilia connexa." 1 have 

 seen the type of tliis, and all the bracts 1 have been able to investigate had a free 

 ligula like the those of typical plants. Winkler states the same fact, and we have 

 not seen any form which could be taken for a hybrid between C. japonica and the 

 following species. They are both always very distinct and easy to recognize.
