This is a very common Rose growing in sandy and rocky places beside streams 

 everywhere in western Hupeh, and in Szech'uan from river-level to 1300 m. 

 altitude. The flowers are always pink and larger than those of the type, and like 

 the type it is a very variable plant. The stems may be prostrate or erect; the leaves 

 vary extremely in size, and the leaflets vary from narrow-lanceolate to suborbicular 

 and are nearly glabrous or very pubescent ; the stipules \ary in size and in degree 

 of lacination, and the pedicels are smooth or densely stipitate-glandular. These 

 characters are all inconstant and in this plant have no taxonomic significance. 



The typical R. muUiflora Thunberg is a native of Japan and has pure white 

 smaller and usually more numerous flowers in the clusters. Rosa mulHfloray var. 

 catkayensis is the wild parent of the double pink forms enumerated below 

 and introduced into England from China in 1804 and in 1816, while the Japanese 

 R. midtiflora was not introduced until sometime about 1860. The first mention 

 of this variety is found in Plukenet (Amalth. 185 [1705]) under the name " Rosa 

 sylvestris cheusanica, foliis suhtus incanisj Jloribus purpureis parids." 



A picture of this Rose will be found under Nos. 014, 019 of the collection of 

 Wilson's photographs.
