Hi jedmar. I looked at the photos of "Ferdinand Pichard", yes, they look quite similar, but not completely. Blooms of "Č.S.R". are light pink with deep pink stripes ("Ferdinand Pichard" seems to be white with deep pink?). Young leaves are very light green, or better said they have unhealthy yellow green colour. I don´t have "Ferdinand Pichard", but compared to the photos here on HMF - "Č.S.R." seems to have more dense prickles. I´ll try to make some photos.
