132 WILSON EXPEDITION TO CHINA 



JAPAN. Hondo: prov. Idzu, Shimoda, C. Wright (type; Herb. N. Pacif. 

 Exp. Ringgold & Rodgers 1853-6; with fruits). Hokkaido : prov. Oshima, Hako- 

 date, July 10, 1890, K. Miyabe & Y. Tokubuchi (with fruits; doubtful). 



Judging by a co-type in Herb. Gray, this may be a hybrid between S. japonica, 

 var. padifolia Seemen and S. vulpina Andersson, but the material is insufficient, 

 and the co-type seems to differ in the shape of the longer, more acuminate leaves 

 and in the partly brownish pubescence of some of the catkins which are put on 

 the same sheet separately from the sterile branch. 



L6veille (in Bull. Acad. Int. Geogr. Bot. XVI. 144 [1906]) mentions U. Faurie's 

 No. 1, from Hondo, "Ubayu, dans les forets," July 1, 1904, as belonging to S. 

 Matsmnuraei, but 1 have not seen this specimen. The same author (in Bull. Soc. 

 Bot. France, LVI. 141 [1905]), describes the d^ form of this species after a specimen 

 from Hondo, prov. Mutsu, Aomori, May 1902, collected by Kinashi (sub No. 10). 

 Not having seen this specimen, I cannot tell if this cf plant really belongs to 

 S. Matsumuraei, the hybrid origin of which has already been suggested by von 

 Seemen.
