Ivory is from Thailand where it is also known as Nang Klang Wan. It is believed to be one of the parents of the Maha Chanok mango.
 
The fruit are long-oblong in shape, medium-sized, turning greenish-yellow at maturity.
The flesh is light in color, is *very* sweet, fiberless, and somewhat insipid. It has a flavor we would liken to sugar cane. The seed is very thin and polyembryonic.
