Tangelo
The tangelo , Citrus × tangelo, is a citrus fruit hybrid of a Citrus reticulata variety, such as mandarin orange or tangerine, and a Citrus maxima variety, such as a pomelo or grapefruit. The name is a portmanteau of 'tangerine' and 'pomelo'. Tangelos are the size of an adult fist, have a tart and tangy taste, and are juicy at the expense of flesh.[clarification needed] They generally have loose skin and are easier to peel than oranges, readily distinguished from them by a characteristic "nipple" at the stem. Tangelos can be used as a substitute for mandarin oranges or sweet oranges.
