The original tree grew from a seed planted in 1936 on the property of E. L. Cushman, in Miami, Florida.

For many decades afterward its parentage was unknown, but a 2005 pedigree analysis suggested that the cultivar was likely a cross between Haden and Amini.

[1] The fruit was recognized as having excellent eating quality, but the trees were poor bearers making the cultivar undesirable for commercial production.

The fruit is round in appearance and yellow when ripe, often looking more like a grapefruit than a mango.

[5] The flesh is pale yellow, completely fiberless, and has a sweet, rich flavor and aroma.
