Hi, Dora. Sorry about the delay.
Rosa macrantha is not a valid species name, so it wasn't automatically added to the database with the accepted species, but I'm happy to list any rose that's exhibited and has an exhibition name. The exhibition name for Rosa macrantha is Gallica Macrantha. I'll create that entry and then come back to give you a link to it.
Rosa virginiana plena is not an accepted species name either, and it isn't exhibited, so it has no exhibition name, but I'm a photo floozy, so if you have a photo to add, I'll be happy to create an entry. Back with the link in a while.
