Notes and observations

3/23/1987, EMN: Fruit is oval shaped, late maturing, virtually seedless. Italy's late variety orange, and is harvested from March through June.

Description from The Citrus Industry Vol. 1 (1967)

"Fruit medium-large, oval; base commonly with low, narrow, slightly furrowed collar; areole faint or lacking; seeds few or none.  Well-colored at maturity, but regreens if held on the tree long thereafter.  Rind medium-thick, very tightly adherent; surface finely pebbled.  Flesh juicy and well flavored at maturity.  Holds especially well on tree with little loss in quality and stores and ships well.  Late in maturity (the latest of Italian varieties and approaching Valencia).

Tree of good vigor and size, slow growing, somewhat irregular in form; leaves light-green and of somewhat distinctive color and appearance.  Pronounced tendency to produce out-of-season bloom and fruit.  Sensitive to cold, heat, and desert winds, but productive under favorable conditions.

Calabrese is the preferred name to distinguish this important variety from others of oval form. 

Of unknown origin, this old Italian variety is widely grown and for decades has ranked as first in importance among common sweet orange varieties in Italy, a position it seems destined to maintain because of its many excellent features."
