130 WILSON EXPEDITION TO CHINA 



A colloquial name for E. glauca in Hupeh is " Ch'ou-la-shu " (stinking Ash 

 tree). It is hardy in England and promises to succeed in the Arnold Arboretum. 



From the description we strongly suspect that E. sutchuenensis Dode also 

 belongs here.

 ch'uan: Mt. Omei, E. Faher (No. 26). 



In western Hupeh and eastern Szech'uan this is a very common shrub in thickets 

 and along the margins of woods. The long narrow leaves with numerous remote 

 pairs of leaflets and the much more slender branches distinguish this species from 

 E. rutaecarpa Bentham. 



Dode quotes from Pere Farges the name " houang pei chou " for this shrub. 

 This name signifies " yellow bark tree " and is very generally applied in central 

 and western China to Phellodendron chinense Schneider, and P. sachalinense Sargent, 

 the bark of which is greatly valued in Chinese medicine. We never heard in 

 China of the bark of Evodia officinalis Dode, having any officinal value, but the 

 fruit is used as a drug and the shrub is known as the Chu-yii, Wu-chu-yii and 

 La-tzu-shu.

Western Hupeh: Hsing-shan Hsien, side of stream, alt. 600- 

 1000 m., December 1907 (No. 791, fruit; bush 2.5). Western 

 Szech'uan: Kiating Fu, roadside thickets, alt. 300-1000 m., Sep- 

 tember and November 1908, November 1910 (Nos. 3572, 9, fruit, 

 3573 > ^} 4568, fruit; bush 1-3 m. tall, flowers white, fragrant, fruit 

 reddish); Hungyah Hsien, thickets, alt. 300-1000 m., September 5, 

 1908 (No. 3573, S, bush 1-2 m. tall, flowers white). 



In western Szech'uan this is a very common low-level shrub but in Hupeh it 

 is comparatively rare. Our specimens agree very well with Dode's short descrip- 

 tion which is based on a specimen from Kueichou province.
