Polyembryonic. Notes from T. Tanaka in CITROLOGIA, pg 24, Univ. Osaka, Japan, 1961: A good bearer & keeps well in storage with very good eating quality. It can be appreciated much better than C. natsudaidai- which objectionally is bitter and acid. No cultural disadvantage is reported. Fruit is regularly obconical in shape and gradually narrowed toward the base. Lvs alate, fr is yellow, rind 10.2 mm, fruit ht 9.3 cm, diam. 10.4 cm. 2/22/88- This appears to be more likely a pummelo hybrid than a grapefruit hybrid and should be housed there- Dr. Bitters concurs. A large, yellow, pyriform fruit; rind moderately rough. Foliage pummelo-like. Rind moderately thick; fruit seedy. Flesh dark yellow, juicy, melting; tolerably edible but tart.
