Note from W.P. Bitters' trip to Japan 1963: "Very small fruit, yellow to yellowish brown, rind 3 mm thick, hollow core, 3 seeds, juicy, rich, very little rag, tangelo taste, appears polyembryonic, too small for commercial use, try as rootstock." A strange mandarin. Very light orange, almost just dark yellow. Puffy, moderately rough rind. Peels & sections well. Flesh light orange, very juicy & sweet, almost acidless. Seeds large, about 1 per section. Section membranes very tough to chew.
