von Sccmen (Salices Japonicae 21) referred several Japanese species which 

 liave only one stamen (at least in part of the flowers) to a new section 

 Sieboldianae, and he also mentioned (p. 13) S, sitckensis, S. CouUeri, and 

 S. iviijlaiiana as belonging to his group Suhmonandrae. Neither he nor I 

 in 1904 when I published the Salices of my III Handb. Laubh. i. G9, were 

 aware of the fact that IJebb had alrciuly proposed a sect. Sitchcnses. In 

 1916 (in Sargent, PI. Wils. iiL 1(51) I dealt with the sect. Sieboldianae, but 

 I do not yet know^ if the Japanese si)ecies really ought to be united with 

 S. sitcJicnsis in the same group. S. JJva-ursi, of whic^h S. ivigtuiiana is only 

 a synonym, cannot be included in this section, and its relationship is still 

 doubtful as I have ab-eady pointed out (in Bot. Gaz. xlvii. 50 [1919]). To 

 whicli of the other American sections the Sitchenses approach most closely 

 is still a question I cannot definitely answer at present.
