I'm writing an article about R. rubrifolia. I have discovered an early source by Johann Scheuchzer describing travels in Switzerland, specifically in the Grinewald Valley, in which he "discovered" a rose in 1709 he names Rosa foliis glaucis rubedine tinctis flore rubro. With the help of the internet I translate this roughly as "Gray-leafed rose with red tinted flowers." Source is Itinera per Helvetiae Alpinas Regiones, Vol. 3, 1706-1709, p. 518 (published in 1723).

Is this a possible first written description of R. rubrifolia?

I am attempting to recreate a timeline of references. This seems to predate others in the literature. My biblio will accompany the article.

Robin's pincushion galls (Diplolepis rosae) are fairly common, you see them on Rosa canina in almost any hedgerow, but never on Rosa arvensis that is just as common as canina often growing amongst eachother. Rosa glauca is the only other rose I have ever found them growing on.
