Excuse my interference. I have not the camellia that is searching you. Only he wanted to ask on your commentary. Camellias of stone. I never listened, nor read on these varieties of stone. Is it possible that I do not understand well your words?. Thank you.
Regards.

I was wrong in the assumption that the Stone varieties were well known. Mr. and Mrs. Stone were collectors and propagators of camellias. One of those she named was Gail Bearden, a niece. Unfortunately, she did not register the name with the American Camellia Society so the name is not well known.
Thank you for your interest.
