322 WILSON EXPEDITION TO CHINA 



A specimen collected on " Gua-in-san " in Shensi by G. Giraldi on July 16, 

 1897, possibly belongs to this species, but the material is too poor for definite 

 determination. The calyx is very setose.

Western Hupeh: Changlo Hsien, thickets, alt. 1300-2000 m., 

 June 1907 (No. 3591 ; bush 1-2 m. tall, flowers rose-red) ; Hsing-shan 

 Hsien, thickets, alt. 1600-2000 m., June, July and September 1907 

 (Nos. 3592, 287^; bush 2-3 m. tall, flowers pink to red); Fang Hsien, 

 upland thickets, alt. 1600-2300 m., July and September 1907 (No. 287; 

 bush 1-2 m. tall, flowers pink, fruit coral-red) ; same locality, June and 

 October 1910 (No. 4418^; bush 3 m. tall, flowers rose-red); Patung 

 Hsien, thickets, October 1900 (Veitch Exped. Seed No. 512); without 

 locality, A. Henry (No. 6071=*). Eastern Szech'uan: Wushan 

 Hsien, thickets, 1300-1600 m., September 1907 (No. 204; bush 

 3 m. tall, fruit orange-red) ; same locality, June 1900 (Veitch Exped. 

 No. 1045; bush 1.5 m.); same locality, A. Henry (No. 5746). 



This is a very common species in western Hupeh in thickets of low-growing shrubs 

 on mountain slopes. The stems are upright, and the more or less reddish-purple shoots 

 and branches are remarkably free of prickles. A specimen collected on "Mt. Kin- 

 tou-san " in Shensi on July 14, 1897 by G. Giraldi may belong to this species, but 

 the material is so poor that it is not possible to discuss it intelhgently. A specimen 

 collected by W. Purdom near Minchou, western Kansu, probably belongs here, 

 though it differs in its perfectly glabrous leaflets.

Crcpin's description supplemented by a photograph of the original specimen 

 in the herbarium of the Museum at Paris leaves little doubt that the specimens 

 enumerated above can be referred only to Rosa Davidii. It is a common Rose on 

 the mountains of western Szech'uan, in Mupin, where David collected it. It is 

 the species in China nearest to R. macrophylla Lindleyi of the western Himalaya. 



1 The different botanists who have dealt with the Roses of the interior of China 

 have referred many specimens to Rosa macrophylla Lindley, but in nearly every case 

 have made them varieties or forms, or have remarked that the specimens diflfer
