Can anyone tell me about Dr. Robert Dunstan? About citrus growers Brown, Chapman, Nagle, you can find at least some grains of information. I didn't find anything about Dunstan, except that he is from Gainesville, FL. As far as I understand, judging by the names, he is the author of "Dunstan citrumelo" and "Dunstan Honey Mandarin"? And the synonym of the latter is probably "Honey Changsha", the seeds of which I got last fall. Who is familiar with the origin of these varieties, or who knows anything about Robert Dunstan? Are his other creations known?
