Hi, let me help you with this
Why do you need this seed? Are you planting it?
If this is for planting, then your question is in the wrong category I will be more than happy to send it to moderator to find the right category for your question.
i wish to plant it.
I could not find anyone selling the actual African Bush Mango Trees, since they are native to Africa. It is also known as a Dika Nut Tree. I have found where the seeds are sold and they have become very popular since people are using them for weight loss.
This link has several distributers that you can conatct about them: http://www.alibaba.com/showroom/african-bush-mango-seeds.html
I hope this information is helpful for you in locating thes African Bush Mango Seeds also known as Dika Nut.
