and Komarov, 1. c, although I have some doubt if all these specimens belong to 

 the typical form. 



There are two other varieties: 



Salix viminalis, var. Gmelinii Andersson in De Candolle, Prodr. XVI. pt. 

 2, 266 (1868), sensu Seemen in Ascherson & Graebner, Syn. Mitteleur. Fl. IV. 

 174 (1908). 



Salix Gmelini Pallas, Fl. Ross. I. 2, 77 (1788), — Ledebour, Fl. Ross. III. 606 

 (pro parte) (1850). — SjTeishtschikof, 0a. Mock. Fyd. II. 33, fig. (1907). 



For additional 8>Tion>Tns see von Seemen, 1. c. 



A tj^po recedit ovariis sessilibus obtusioribus stigmatibua valde elongatis an- 

 gustis stylo breviore plus minusve superantibus coronatis. 



This seems the S. viminalis of most parts of Russia and western Siberia, but is 

 apparently wanting in eastern Siberia. 



Salix viminalis, var. yezoensis Schneider, n. var. 



A iypo recedit ovariis sessilibus stigmatibus brevibus angustis stj'lo longo multo 

 brevioribus coronatis. 



JAPAN. Hokkaido: prov. Ishikari, Sapporo, 1878 (cf and 9); same place, 

 May 26 and Oct. 15, 1890, Y. Tokubuchi (sterile); same place, April 17, 1891, Y. 

 Tokubuchi (No. 17, type; 9); same place, April 17, 1893, Y. Tokubuchi (9); 

 same place, April 29, 1906, K. Kondo (d^); same place, " secus aquas," June 14, 

 1908, U. Faurie (No. 255; with fruits); same place, April 28 and May 5, 1913 (ex 

 Herb. Sakurai ; cf and sterile). Hondo: prov. Rikuchu, Mt. Iwate, May 5, 

 1911 (co-type, cf, ex Herb. Sakurai); prov. Musashi, Kichijoji, April 12, 1914, E. 

 H. Wilson (No. 6419; small bushy tree, branches erect spreading; cf). 



See von Seemen, 1. c. (1903) . The short stigmas seem to be the only real difference 

 compared with certain forms of var. typica. Sometimes var. yezoensis may be diffi- 

 cult to distinguish from forms of S. opaca Andersson (see p. 159), and it needs further 

 investigation to decide whether certain forms are to be regarded as hybrids or not. 



143. Salix sachalinensis Fr. Schmidt in M^m. Acad. Sci. St. Petersbourg, ser. 7, 

 XII. 173 {Reis. Amurl. Sachal.) (1868). — Herder in Act. Hort. Petrop. XI. 429

Salix korsakoviensis L^veille in Bull. Soc. Bot. France, LVI. 302 (1909). 

 Salix stipularis, var. sachalinensis Koidzumi in Tokyo Bot. Mag. XXVII. 94 

 (1913). 



NORTHEASTERN ASIA. Saghalien : "beim Posten Dui am Bach Anfang 

 Juni 1860," Fr. Schmidt (sub nom. S. sachalinensis; 9); same place? Fr. Schmidt 

 (sub nom. S. stipularis; cf flowers and old leaves); without locality "secus aquas," 

 June and July 1908, U. Faurie (No. 274, 9 type, and Nos. 275, 276, leaves of S. 

 korsakoviensis. 



JAPAN. Hokkaido: prov. Oshima, Hakodate, 1861, C. Maximovncz (No. 1; 

 9); prov. Ishikari, near Sapporo, June 12-13, 1908, U. Faurie (No. 265, 270; with 

 fruits; stigmas short). Northern Hondo : prov. Mutsu, Iwagi-san, May 1905, 

 U. Faurie (No. 6609; 1-2 m. tall; c^; No. 6610; 9). 



All these specimens have short-stalked ovaries, the pedicel being shorter than 

 the gland, and styles about as long as the ovaries with comparatively short stigmas 

 yi the length of the style. The 9 catkins appear with the young leaves, which are 

 silky beneath but soon become glabrous and pale green, not glaucous. The old 

 leaves of Faurie's No. 276 are up to 17 cm. long and 3.5 cm. broad, acute at the 

 base, and coarsely crenate with veins prominent beneath.
