'R. farreri' rose References
Article (magazine) (1 Jun 2015) Page(s) 285. Some diploid species (R. farreri Cox and R. koreana Kom.) that were previously included in R. sect. Pimpinellifoliae but are resolved in the Cinnamomeae clade are morphologically distinct from other members of the section by having bracts and sometimes pink or red flowers. These distinct species seem to be genetically close to R. sect. Cinnamomeae as suggested by the GAPDH analyses and should probably be transferred to R. sect. Cinnamomeae, as noted in the taxonomic revision by Roberts (1977).

Book (2001) Page(s) 415. ...found in the south of the province [of Kansu], was a species rose which blooms in June and has pale pink or white flowers which develop into luscious coral hips; its pretty fern-like leaves turn purple and crimson in the autumn. The particular variety usually offered was selected from a batch of Farrer's seedlings sent to his friend and fellow plantsman E. A. Bowles (1865-1954), and was Rosa persetosa var. farreri (now. R. elegantula). It is sometimes remembered as the Threepenny-bit Rose because of the size and shape pf the flower - although the eight-sided bronze threepenny bit is hardly remembered by anyone nowadays.

R. elegantula Rolfe R. farreri Stapf ex Stearn A deciduous shrub a few feet high, the young sucker shoots copiously armed with short, slender prickles; branchlets sparingly armed...Leaves 2 to 4 inches long...seven to eleven leaflets...Flowers soliary or a few together, 1 to 1½ in. wide, rich rose...sometimes pale pink or white...Fruits brigth red, top shaped...the sepals persistent. Native of north-western and west-central China; described from plants raised by Veitch from seeds collected by Wilson....allied to R. sertata... The stock of R. elegantula was sold at the winding-up sale of Messrs J. Veitch in 1913, but this species does not seem to have been much cultivated outside Kew. Indeed, its very existence was overlooked when the plants from Farrer's re-introduction were being considered, for there is no doubt that R. farreri and R. elegantula are the same species. Even the following selection [R. elegantula 'Persetosa'] does not differ from the type in any significant botanical character....
