SALICACEAE. — SALIX 131 



fruits); "in planitie Sambongi," May 8, 1905, U. Faurie (No. 6595; c^). 

 Kyushu: prov. Hizen, Nagasaki, 1862, R. Oldham^ (No. 551, type of S. 

 Miquelii, ex Andersson). 



The typical S. vulpina to which the above specimens are referred seems to be dis- 

 tinguished by the pale-green under surface of its leaves, its glabrous ovaries and 

 by the reddish brown or gray and brown hairs of its bracts. There are also 

 described the following varieties: 



Salix vulpina, var. discolor Seemen, Salic. Jap. 40 (1903). 



Folia subtus discoloria, cinerea v. rubescenti-cinerea. 



NORTHEASTERN ASIA. OchotsSea: without precise locality, J. 5maH 

 (in Collect. Wright). 



JAPAN. Hondo: near Mount Indonosan, July 22, 1887 (No. 21, type; ex 

 Herb. Tokyo, ex Seemen; 9). Hokkaido: Oshima, July 10, 1890, K. Miyabe & 

 Y. Tokubuchi (with fruits). 



Small's specimen seems to be a co-type of Wright's No. 4 mentioned by Anders- 

 son (1867), and S. Miquelii sensu stricto seems to belong to this variety, which, 1 

 suppose, is not identical with the hybrid S. kakista Schneider, p. 128. 



Salix vulpina, var. nikkoensis Koidzumi in Tokyo Bot. Mag. XXVII. 90 

 (1913). 



" Ovaria subsessilia, glabra ; stigmate obscuriter bilobulato; bracteis albo-tomen- 

 tosis, florum 9 suborbicularibus, cf obovato-ellipticis." 



JAPAN. Hondo: prov. Shimotsuke, Nikko (ex Koidzumi). 



Not having seen a specimen, I cannot judge the value of this form. It may belong 

 to S. kakista Schneider, see p. 128. 



Salix vulpina, var. pubescens Koidzumi, 1. c. (1913). 



" Folia adulta utrinque secus costas pubescentia." 

 JAPAN. Southern Hondo (ex Koidzumi). 

 I have not seen this form. 



Salix vulpina, var. coriacea Koidzumi, 1. c. (1913). 



" Folia rigide coriacea." 



JAPAN. Hokkaido: prov. Oshima; Hondo: prov. Mutsu (ex Koidzumi). 



This seems to me a very doubtful form. 



As far as I can see, S. vulpina Andersson may produce hybrids with several 

 species. 1 have already mentioned S. daiseniensis Seemen, p. 129, and S. kakista 

 Schneider, p. 128. Another hybrid may be S. Matsumuraei Seemen, see below. 

 An interesting form seems to be S. vulpina, var. tomenlosa Koidzumi, 1. c. 265 

 (1913), from Hondo, prov. Shinano, Togakusimura, and prov. Kaga, Kanazawa. 

 This has very hairy leaves and fruits. Koidzumi's description is insufScient, and 

 I have not seen a specimen. 



93. Salix Matsumuraei Seemen, Salic. Jap. 71, t. 78, A-B' (1903). 



Salix vulpina, var. Matsumuraei Koidzumi in Tokyo Bot. Mag. XXVll. 90 

 (1913). 



^ The co-types seen by von Seemen and myself belong to S. Harmsiana Seemen, 

 Bee p. 163. Koidzumi does not mention any specimens of S. vulpina from 

 Kyushu.
