Determined by Alfred Rehder. 



STACHYURUS Sieb & Zucc. 



Stachyurus chinensis Franchet in Jour, de Bot. XII. 254 (1898). — 

 Diels in Bot. Jahrb. XXIX. 475 (1900). 



Stachyurus praecox Diels in Bot. Jahrb. XXIX 475 (non Siebold & Zuccarini) 

 (1900). 



Kiangsi: Kuling, thickets, common, alt. 1300 m., July 30, 1907 

 (No. 1725). Western Hupeh: north and south of Ichang, ravines, 

 alt. 300-1000 m., April and August 1907 (No. 89); Changyang Hsien, 

 alt. 300-1000 m., August 1907 (No. 192, fruiting branches); Fang 

 Hsien, thickets, alt. 2000 m., September 1907 (No. 292); Hsing-shan 

 Hsien, thickets, alt. 1000-1800 m.. May and June 1907 (No. 2556). 

 Ichang, glens, March 16, 1900 (Veitch Exped. No. 125); without 

 locality, A. Henry (Nos. 2002,3770, 6917, 5744). Shensi: Tai-pei- 

 shan, 1910, W. Purdom. Szech'uan: Nanch'uan, A. von Rosthorn 

 (No. 2000). Yunnan: Longki (flowers) and Chang-fong-shan (fruits), 

 J. M. Delavay (in herb. Paris). 



The Kiangsi and Hupeh plants differ from the type in the somewhat thinner 

 and sometimes subcordate leaves. In addition to the characters given by Franchet, 

 this species may be distinguished from S. praecox Siebold & Zuccarini by the 

 broader and crenately serrate leaves, abruptly contracted into a long acumen, 

 by the greenish or duU brown color of the one year old branchlets, and by the smaller 

 fruits, while in S. praecox the serratures of the generally oblong-ovate leaves are 

 more flaring and the one-year old branchlets are chestnut brown and lustrous. I 

 have not been able to find among the Chinese specimens any representing the true 

 S. praecox, and I believe that all the Chinese specimens referred to that species 

 belong to S. chinensis or possibly to S. himalaicus.
