"Citrus unshiu is a seedless and easy-peeling citrus species, also known as unshu mikan,[1] cold hardy mandarin,[2] satsuma mandarin,[2] satsuma orange, naartjie,[2] and tangerine.[2]
Under the Tanaka classification system, Citrus unshiu is considered a separate species from the mandarin. Under the Swingle system, unshius are considered to be a group of mandarin varieties.[7] Genetic analysis has shown the Satsuma to be a highly-inbred mandarin-pomelo hybrid, with 22% of its genome, a larger proportion than seen in most mandarins, coming from pomelo."
