 Salix hirosakensis Koidzumi in Tokyo Bot. Mag. XXVII. 264 (1913).

 Faurie (No. 6602, type of var. hirosakensis, 9 ); Aomori, in streets, May 1905, U. 

 Faurie (No. 6622; 9 ) ; " basi mentis Iwagisan in pago Dake," May 1905, U. Faurie 

 (No. 6601; (^); Hokkaido : prov. Ishikari, " in planitie Sapporo," June 14, 1908, 

 U. Faurie (No. 256; 9). 



Koidzumi founded S. hondoensis on a specimen from Sapporo without mention- 

 ing a precise type. Taking up the name hirosakensis he says: floribus femineia 

 saepe biglandulosis. In Faurie's type the 9 flowers have only one gland, but 

 otherwise the specimen looks very much like *S. eriocarpa Franchet & Savatier. 

 The d' flowers in No. 6601 have rather small glands sometimes appearing like 

 a single ventral gland almost surrounding the pedicel. Our species certainly is 

 very nearly related to S. eriocarpa and *S. jessoensis Seemen. Whether they are 

 hybrids or varieties of one species has not yet been determined. 



30. Salix Makinoana Seemen in Fedde, Rep. Spec. Nov. I. 173 (1905). 

 Salix gymnolepis Leveille in Fedde, Rep. Spec. Nov. III. 22 (1906). 



Salix puj-purea, subspec. gymnolepis Koidzumi in Tokyo Bot. Mag. XXVII. 

 267 (1913). 



JAPAN. Hondo: prov. Mutsu, "in sylvis Aomori," May 1904, JJ. Faurie 

 (No. 5761, type, 9 , ex Seemen), " in plateis Aomori," May 1904, U. Faurie (No. 

 2769; co-type, 9, ex Seemen); Hirosaki, "secus rivos," May 1905, U. Faurie 

 (No. 6615, type of S. gymnolepis; 9 ). 



This species has been very differently interpreted by Koidzumi, 1. c, but unfortu- 

 nately 1 have not seen one of von Seemen's tj^pes. Koidzumi says, that No. 5761 

 partly belongs to S. stipularis Smith (in which he includes S. opaca Andersson and 

 S. sachalinensis Schmidt, see p. 143), and partly to S. Miyabeana Seemen, see 

 p. 166. No. 2769 is referred by Koidzumi to his subspec. gymnolepis. Leveille's 

 type agrees very well with von Seemen's good description of S. Makinoana. Other- 

 wise *S. gymnolepis Leveille much resembles S. hondoensis Koidzumi {S. dolichostyla, 

 var. hirosakensis Koidzumi). The bracts are not perfectly glabrous, as L6veille 

 says, but hairy at the base. The ovaries have very short pedicels, as indicated 

 by von Seemen for S. Makinoana, and von Seemen's whole description of the 

 9 flowers and fruits fits exactly the specimen of S. gymnolepis L6veille before 

 me. 1 believe that S. Makinoana Seemen and S. gymnolepis Leveille are nearly 

 related to S. hondoensis Koidzumi and have no connection with S. purpurea 

 Linnaeus. 



31. Salix jessoensis Seemen, Salic. Jap. 31, t. 3, fig. f-l (1903). 



JAPAN. Hokkaido: prov. Ishikari, Sapporo, Park, August 23, 1914, E. H. 

 Wilson (No. 7414; tree 15-17 m. tall, girth 2.4-3.9 m., bark grayish, shallowly 

 fissured; sterile); same locality, May 18, 1891, Y. Tokubuchi (type, ex Herb. Sap- 

 poro Coll., 9 and cf); same locality. May 1890, Y. Tokubuchi; same locality. May 

 11, 1892, Y. Tokubuchi {d"); same locality, July 1, 1891, Y. Tokubuchi (sterile). 



The sterile specimen of Tokubuchi has very hairy yellowish brown branchlets 

 (suckers?), and the leaves are up to 13.5 cm. in length and 3 cm. in width and 

 grayish and loosely silky beneath; the petioles are about 1 cm. long, and the stip- 

 ules are broadly ovate at the base, very acuminate at the apex and ^ the length 

 of the petioles. This species differs from S. eriocarpa Franchet & Savatier and
