CHINA. Formosa: Tamsui, A. Henry (No. 1404; d"; No. 1473, sterile), 

 creek, February 24, A. Henry (No. 1068*; tree 3-5 m. tall; with fruits). May 

 8, A. Henry (No. 1068^; with old fruits); Ta kao, bank of creek far in (3 miles), 

 July 15, A. Henry (No. 1068; tree 3-5 m. tall; with fruits); Banchoryo, 1909, aS. 

 Kusano (tj^pe of var. Kusanoi, ex Hayata). 



This species is readily distinguished by the brownish pubescence of its young 

 parts, the coarsely serrate multi-nerved leaves, the short fruiting catkins, and by 

 the nervation of its old leaves. It appears to be nearly related to S. tonkinensis See- 

 men or to some of those forms of S. tetrasperma Roxburgh of which 1 have not yet 

 been able to see sufficient material. 



14. Salix Maximowiczii Komarov in Act. Hart. Petrop. XVIII. 442 (1901) ; XXII. 

 25, t. 1 (Fl. Mansh. II.) (1903); XXV. 813 (1907). — Nakai in Jour. Coll. Sci. 

 Tokyo, XXXI. {Fl. Kor. 11.) 214 (1911). 



NORTHEASTERN ASIA. Korea: " in montibus Zatan-ien secus rivulos in 

 regione fl. Jalu," June 28, 1897 (type, ex Komarov); " in monte des Diamants," 

 June 24, 1906, U. Faurie (No. 177). 



According to von Seemen {Salic. Jap. 25 [1903]) this species is the same as S. 

 cardiophylla Trautvetter, see p. 103, which is not mentioned either by Komarov 

 or by Nakai, although Komarov says (1907) that S. Maximowiczii is a very dif- 

 ferent species. The plant collected by Faurie agrees very well with Komarov's 

 description and plate. The ovate-lanceolate, long-acuminate leaves measure up to
