good luck

In searching the web,(curious as to what this is!) I found a note that Spondias Cytherea is also referred to as Spondia Dulcis. This may or may not be correct: "The ambarella once called Spondias cytherea is now called Spondias dulcis by many." Spondias dulcis seed are listed as available from a place called 'Green Dealer' linked below. If you don't think this is the same thing, have you thought of buying the fruit and saving the seeds?

Here is a link that might be useful: Spondias Dulcis
