Last month, a friend from Gambia was supposed to bring a bunch of madd fruit for me. He purchased these:

But, he was able to bring back only one fruit

. By the time, this single fruit reached me, it had already began to spoil and looked like this:

Also the fruit had started to ferment. On cutting it open, it was already spoilt.

But, I managed to salvage the seed

Finally after nearly a month, a couple of them have sprouted.

I just want to confirm that this is Saba senegalensis and not some other Landolphia specie.
