Biological Characteristics
Citrus fruits are usually self-fertile (needing only a bee to move pollen within the same flower) or parthenocarpic (not needing pollination and therefore seedless, such as the satsuma).
Blossoms from the Dancy cultivar are one exception. They are self-sterile, and therefore must have a pollinator variety to supply pollen, and a high bee population to make a good crop. The fruit is oblate.

Famous quotes containing the word biological:
“In America every woman has her set of girl-friends; some are cousins, the rest are gained at school. These form a permanent committee who sit on each other’s affairs, who “come out” together, marry and divorce together, and who end as those groups of bustling, heartless well-informed club-women who govern society. Against them the Couple of Ehepaar is helpless and Man in their eyes but a biological interlude.”
—Cyril Connolly (1903–1974)
