Could anyone please tell me if this rose is dumalis? I live in the far south-west of England where Rosa arvensis and Rosa canina are very common hedgerow and woodland plants, however there is also another very distinct rose growing too. It occurs a single plants in hedges and sometimes grassy areas too, I would estimate at less than 1% of the local rose population. The flowers are far darker than Rosa canina, like Rosa rubiginosa, very similar to the picture posted by Rosenschule Ruf. The fruits are lager than canina with very obviously persistent calyces (calyx). The leaves have a bluish glaucus sheen and the prickles are thin, curved and fiercely sharp, more similar to arvensis than the chunky dog's teeth of canina. The pedicels are bristly and shorter than Rosa canina. One reference book; W. Keeble Martin, The Concise British Flora in Colour, describes this as the "Short-Pedicelled Rose".
The picture of the leaves show Rosa canina and Rosa arvensis above for comparasion and dumalis below.
It looks very, very close to Rosa dumalis (Bechst.), however all the books say it should not be growing in my part of the country only in the north! I wonder if members have any comments or suggestions?
