ROSACEAE, ROSA 321 



This Rose is common in wayside thickets and on the banks of rivers in Shih- 

 ch^uan Hsien, but is rare elsewhere so far as known. 



Our specimens are in fruit only, but they agree exactly with Henry's; and we 

 think that Henry is right in considering this plant to be the wild type of Rosa chi- 

 nensis Jacquin. The Rosa lucidissima Lcveill^ (in Fedde, Rep. Spec. Nov. IX. 444 

 [1911]; FL Kouy-TcMou, 254 [1914]) appears to us to be nothing but a state of 

 this forma spontanea distinguished only by its leaves being pale green on the under- 

 side and not glaucescent and by the calyx-tube being densely covered with stipitate 

 glands.

Western Hupeh : Changyang Hsien, cultivated, alt. 600 m.. May 

 1907 (No. 4728; bush 1-2 m., flowers red); Hsing-shan Hsien, June 

 1901 (Veitch Exped. No. 1294; bush 1 m., flowers red, an escape). 



This Rose is occasionally seen in Chinese gardens, but not very often. Our 

 specimens have rather small red semi-double flowers and agree with Meyer's var. 

 Chamissoniana in the almost entire absence of bristles on the branches and in 

 the smaller and narrower, less rugose leaflets; the form enumerated by Pampanini 

 is probably identical. 



Rosa caudata Baker in Willmott, Gen. Rosa, II. 495 (1914). 



Western Hupeh: Fang Hsien, thickets, alt. 1800 m., September 

 1907 (No. 306; bush 1-2 m., fruit coral-red); same locality, alt. 2000 

 m., October 1910 (No. 4418; bush 3-4 m. tall, fruit orange-red). 



This is a rare and very distinct species with erect shoots sparingly clad with 

 stout, straight prickles dilated at the base, prominent winter-buds, large leaves 

 and stipules and a large slightly convex corj-mb and handsome fruit- It is only 

 known to us from the high mountains of northwestern Hupeh.
