CHINA. Yunnan: Mengtsze, alt. 1800 m., A. Henry (No. 9338, type d 
tree 6.5 m. tall); same locality, alt. 1600 m., near water, A. Henry (No. 9338° 9 
co-type, 93384; 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 
& flowers of that species have 8-9 stamens. As long as the Indian forms are 
clearly limited, it seems better to keep those from China distinct. 
The g' 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 dpatés, slender, and eráyvs, spike.
