Be more specific.
There are several peppers from Africa/Mombosa.
Are you asking about the Cayenne Types?
There are bird types etc.
Pics wouldn't hurt or just local names of possible land race varieties you are looking for.

A lot of vendors sell stuff as African this or that.
I have traded with a couple people from Africa that have sent me seeds from many local markets in several places in Africa.
I might have something you are looking for to trade.
You need to be more specific.

Sorry I don't have Any pictures and really don't have any more specifics. I had gotten some ground up pepper labeled Mombasa from the local spice store. I was somewhat hot with a little sweet undertone. I will try to get some more info. As for as trade I only have Peter and some ghost seeds from last year. This year I have planted some Carolina reaper,7 pot dougalh,lemon drop,atomic starfish,and some butch t's.
