CHINA. Yunnan: Mengtsze, alt. 1800 m., A. Henry (No. 9338, type cf; 

 tree 6.5 m. tall); same locaUty, alt. 1600 m., near water, A. Henry (No. 9338=, 9 

 co-type, 9338*^; tree 1.5-3.5 m. tall; with fruits) ; same locality, southeastern moun- 

 tain forests, alt. 1800 m., A. Henry (No. 11250; tree 3 m. tall; 9). 



This species certainly is very nearly related to S. tetrasperma Roxburgh, but the 

 c? flowers of that species have 8-9 stamens. As long as the Indian forms are not 

 clearly limited, it seems better to keep those from China distinct. 



The cf flowers of S. araeostachya Schneider do scarcely differ from those of S. 

 Kusanoi Schneider, but the leaves of the Formosan plant have a different pubes- 

 cence, shape, serration and reticulation. 



The specific name is derived from apaios, slender, and araxvs, spike. 



5. Salix Balansaei Seemen in Bot. Jahrb. XXIII. Beibl. LVII. 44 (1897). 

 INDO-CHINA. Tongking : Hanoi, near the lake, December 1890, B. Balansa 



(No. 4999, type, 9; tree 4-5 m., ex von Seemen); same locaUty, August 1891, B. 

 Balansa (No. 4753; sterile, ex von Seemen). 

 According to the description this species seems most nearly related to S. tetra-
