yes ya'll are correct...a sweet, easy peeling citrus, mostly seed free....I hadn't heard that it was a plum also...and we too have a town in louisiana named Satsuma....Jogeephus, i've got a meyer lemon aslo, along with grapefruit, and satsuma.. the meyer has bore about 250 big lemons for the last 10 years..the grapefruit about 100 for the last 4 years and the satsuma about 150 for the last 5 years...I only asked the question because when i brought some satsumas up to the farm in Mississippi, about 60 miles to our north, no one knew what they were...have a great weekend !!!
