I noticed that when I typed the words "grapefruit" and "citrus" into the search by tree name the data base found nothing. So there must not be a SC champion tree of any variety of citrus. It might be fun to measure the Summerville tree and Mr. Croxton's tree and submit the largest tree for inclusion in the Champion tree. With no citrus in the records, one of them would automatically be the champion untill a larger entry was found. - Millet
