The seed parent of this new fruit was a tangelo resulting from one of the early crosses in the same group with the Thornton, which it somewhat resembles. Because of its first fruiting at Indio, in the general region of San Jacinto Mountain, a famed landmark guarding the pass to the Salton Basin, it is proposed to call this the San Jacinto tangelo. Introduced in 1931. Shown little promise in Florida, because of the "bottle neck" at the stem end of the fruit and its tendency to become insipid early in the season. Has produced early ripening fruit of good size and flavor and of better keeping and shipping qualities than the Thornton tangelo. This tangelo, unlike the Sampson and most of the citrus hybrids so far investigated, does not come true from seed. Fruit round oblate, with slight depression at blossom end, usually with slightly raised area surrounding calyx, not constituting, however, a bottle-neck protrusion ; size ranging from 3 inches in transverse diameter by 2 3/4 inches in height to 2 1/2 inches in transverse diameter by 2 3/8 inches in height; color orange yellow (Ridgway, orange buff to capucine yellow) ; rind fairly smooth and thin (about one-eighth inch), fairly free peeling though not loose; oil cells numerous, very minute and flush with surface, with some larger oil cells interspersed and slightly indented; segments 10 to12, fairly large open core, one-half inch in diameter ; seeds fairly numerous,25 to 30, closely grouped at center, very small and slender, striate, with curved beak and greenish cotyledons ; pulp of pale amber color (Ridgway, pale orange yellow), very juicy, translucent, and tender, little fiber, sprightly, subacid flavor, resembling the Thornton tangelo but when fully ripe having more character than a fully ripe Thornton tangelo ; pulp vesicles irregular in shape and size and near the center more or less split open. Tree evergreen, vigorous, and productive; leaves unifoliate, pointed oval, variable in shape, and size, small to medium size (averaging 2 1/2 to 3 inches long by 1 1/4 to 1 3/4 inches wide), petioles very narrowly winged, occasionally without abscission.
