Source: Received as seed from F.E. Gardner, Orlando, Florida, 1950.
Parentage/origins: Parents unknown.
Rootstocks of accession: Own roots.
Season of ripeness at Riverside: Year round
Season of flowering at Riverside: May to July
Notes and observations:
EMN, 5/1987: Both original seedling trees planted in 18B died. Replant of 1984 now looks good; another will be grown for 1988. If these trees both die, this accession should be kept only in the GH & LH at CRC.
EMN, 12/22/1987: Open growth, not as attractive as Aegle marmelos. No fruit yet.
EMN, 1/24/1990: Fruit similar to Aegle marmelos but more spherical to slightly elongate in shape, and slightly larger on average. Also probably more fruits with dark blush on this accession.
