Translation:A tangerine is a fruit.
According to Wikipedia:
만다린 = mandarin orange (this is the purebred wild-type line, the others are all hybrid cultivars of based on this with a bit of the pomelo/shaddock, and regular oranges are too)
귤 = tachibana orange (though tachibana=橘 is also an old, general word for (flowering) citrus-fruit trees in Japanese)
온주귤 = satsuma (in the Southern US or Britain, mikan in Japanese)
편귤 = tangerine
