SALICACEAE. — SALIX 163 



before the leaves and are almost sessile. In S. Sieholdiana Blume the 9 bracts 

 seem to be somewhat longer (ovate-lanceolate) and the stigmas shorter than in 

 S. Buergcriana.

JAPAN. Kyushu: April 1875, J. Rein (co-type, ex von Seemen); Goto 

 Island, May 1901, U. Faurie (No. 4995, type, ex von Seemen); Mt. Aso, June 

 20, 1899, U. Faurie (No. 3694; co-type, ex von Seemen). Hondo: Daisen, May 

 26 and 28, 1899, U. Faxirie (Nos. 3705, 3706, 3708, ex von Seemen). 



This species seems most closely related to S. Buergeriana Miquel, from which ac- 

 cording to von Seemen it chiefly differs in its shorter female catkins, which appear 

 with the leaves on short peduncles, and in its somewhat shorter pedicels and styles. 

 I have not seen any specimen I could positively refer to it.

JAPAN. Kyushu: Nagasaki, 1862, R. Oldham (No. 551, in part, t>i)e, cP, 

 ex von Seemen; No. 551, in part; 9, co-type in Herb. Gray); Hondo: prov. 

 Shinano, July 1894 (No. 113 ex Herb. Tokyo; doubtful form with fruits). 



This is a doubtful species very near S. Buergeriana Miquel, but, according to von 

 Seemen, differing in its nearly sessile short ovaries with very short stigmas resem- 

 bling those of S. purpurea Linnaeus. The 9 co-type which I have seen shows 

 distinct pedicels and styles, the flowers resembling those of *S. Buergeriana Miquel. 

 The specimen from Shinano has nearly sessile ovaries but a distinct style and 

 remains doubtful. It may be a hybrid between <S. purpurea Linnaeus and S. Buer- 

 geriana Miquel. 



154. Salix propitia Koidzumi in Tokyo Bot. Mag. XXVII. 266 (1913). 

 Salix Sieholdiana, y sikokiana Koidzumi, 1. c. 93 (1913). 



JAPAN. Sikoku: prov. Awa, Tsurugi-san (ex Koidzumi). 



Koidzumi says: " Amentis floribusque iis S. Matsumuraei Seemen simillimis; 

 fohis iis S. Sieholdianae Blume valde affinis, sed tenuioribus subtus secus costaa 

 adpresse sericeo-villosis." This is a doubtful form, of which only the 9 plant is 

 known. It has been omitted from the key.
