Diels in Bot. Jahrb. XXIX. 475 (1900). 
Stachyurus praecoz Diels in Bot. Jahrb. XXIX 475 (non Siebold & Zuccarini)

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 dull brown color of the one year old branchlets, and by the smaller 
fruits, while in S. praecoz 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. praecoz, and I believe that all the Chinese specimens referred to that species 
belong to S. chinensis or possibly to S. himalaicus.
