The list of citrus trees contained on this website is not comprehensive. Only those I own are shown. As other varieties are acquired, they will be added. Currently, I own lemon, lime, kumquat, orange, mandarin, and tangelo trees.
The hierarchy chosen on this site is modeled after the Swingle taxonomy with amendments based on the latest genetic testing. Swingle is not a perfect taxonomy but is probably the most commonly used and fairly accurate. Considering its age, the Swingle taxonomy has held up miraculously well.
