314 WILSON EXPEDITION TO CHINA 



(No. 4454); " Brousses et haies a Long-ky, 700 m., Juin 1911," E. E. 

 Maire (type of R. Willmottiana L^veille). India : east Bengal, Griffith 

 (No. 2140) ; Khasia, alt. 600-1600 m., J. D. Hooker & T. Thomson; 

 Khasia, " environs of Tserapiindzi till near Mdirong," alt. 900-1500 

 m., October 1855, Schlagintweit (No. 209). 



This species, heretofore known only from a few specimens, has been variously 

 considered a good species or a geographical form of the European R. sempervirens 

 Linnaeus. It is really a very distinct species related to Rosa Brunonii Lindley, 

 but readily distinguished from that species by its glabrous reddish brown shoots, 

 more coriaceous, shining green leaves and especially by its much larger fruit and 

 by the hairy back of its petals. 



This Rose is common in thickets round the base of Mt. Omei and in other warm 

 parts of southwest Szech'uan and apparently also in Yunnan extending westward 

 to Khasia and possibly beyond. It is a large rambhng shrub and is very beautiful 

 when in flower or in fruit. The leaves persist late into the winter and in the most 

 favorable locations it may be evergreen. No. 4876 from Mt. Omei has leaves and 

 leaf-rhachis rather more pubescent than is usual ; otherwise the specimens are re- 

 markably uniform in character. Forrest's No. 4454 determined by Focke as R. 

 Soulieana doubtless belongs to this species, though at the first glance it looks rather 

 different with its small elUptic, not acuminate leaflets, but the pubescent petals 

 at once remove it from R. Soulieana Crepin.

Western Szech'uan: near Monkong Ting, valley of Hsao-chin 

 Ho, alt. 2300-3300 m., June 1908 (No. 3613; bush 2-6 m. tall, flowers 

 sulphur-yellow changing to white); between Mao-chou and Sungpan 

 Ting, valley of Min River, alt. 2000-2600 m., August 1910 (No. 4164; 

 bush 2-4 m. tall); west of Tachien-lu, valley of Yalung River, alt. 

 2800 m., June 1904 (Veitch Exped. No. 3532; bush 2 m., flowers yel- 

 lowish). Yunnan: Machi-chiang valley, alt. 3000 m., June 1906, G. 

 Forrest (2370). 



Wilson's specimens from western Szech'uan have perfectly glabrous receptacles 

 and leaves, while in Forrest's specimen the receptacles and pedicels are covered 

 with a short glandular pubescence and the leaves are pubescent on the midrib 

 beneath. 



Common in the warm dry river-valleys of the Chino-Thibetan borderland up to 

 3000 m. altitude. A picture of this Rose will be found under No. 145 in the col- 

 lection of Wilson's photographs and also in his Vegetation of Western China, No. 454.
