 Carpinus Tschonoskii, var. Henryana Winkler in Englcr, PJlanzenr. IV.-61,

Western Hupeh: Hsing-shan Hsien, woods, alt. 1600-1900 m., 

 November 1907 (N0.645; tree 7-lOm. tall, girth 0.6-0.9 m.; old fruiting 

 branchlets) ; same locality, June 1907 (No. 645''; young fruits). Eastern 

 Szech'uan: Wushan Hsien, A. Henry (No. 7063, type; ripe fruits). 

 Western Szech'uan: Mupin, woods, alt. 1900-2200 m., October 

 1908 (No. 1226; tree 13-17 m. tall, girth 1.5-1.8 m.; with ripe fruits); 

 northeast of Tachien-lu, Ta-p'ao-shan, forests, 2100-2900 m., July 3, 

 1908 (No. 2210; tree 12-20 m. tall, girth 1.2-2.1 m.; with young fruits) ; 

 between Lungan Fu and Sungpan Ting, woods, alt. 1600-2400 m., 

 September 1904 (Veitch Exped. No. 4488; with ripe fruits). 



This is an interesting species of which the type differs a little from the other 

 specimens enumerated above. But the serration is quite distinct from that of 

 C. polyneura Franchet to which the type was referred by Burkill. The specimen 

 from Mupin looks rather distinct and may even represent a good variety, but this 

 question needs further investigation because there are too many intermediate char- 

 acters in all these specimens. Nevertheless I think it best to add a description of 

 Wilson's No. 1226, alluding to its differences from the type which was not sufficiently 

 described by the author; the indications put in parenthesis ( ) refer to the type.
