Notes and observations
From Japan. Japanese name: Hiroshima-natsuzabon. A cultivar known only from the inland sea region. Another Natsuzabon recorded from Kyushu is quite different from this.
2/22/1988, EMN: This accession is more like pummelo than grapefruit and should be carried as a probably pummelo hybrid; Dr. Bitters concurs. Leaves are somewhat narrower than most pummelos and young growth is not pubescent. Fruit is like a large pummelo. Rind deep yellow, moderately rough, thick. large pithy core; seedy. Flesh light yellow with just a touch of pink at outer edge of sections; raggy; sour; only moderately juicy.
2/26/1990, EMN: This is probably NOT C. hiroshimana (Natsuzabon), but is probably a hyrid of it. C. hiroshimana was imported from Japan as budwood in 1983, CRC 3904, and is very different from this cultivar.
Not commercially available in California.
