Looks Ghost or Naga. I have similar peppers to that and am in the same situation. I know I planted Black Nagas and Peach Ghosts in that aria of my garden but Im not sure what is what between the two. Leaves seem to match , just have to see when the ripen.

Thanks Dave. No nagas here only ghost. So I found the ghosts yay! For anyone else looking for their ghosts I guess that is the trick, jagged leaves with light green immature pods. I pulled two branches from different plants together and took a pic to show the difference in the green in immature pods. Now I know, the one on the left is a fatali ( dark green) the pods on the right are ghosts (light green). Have you noticed if these characteristics are true even when the color of the bhuts or nagas var ( I.e chocolate, peach, yellow)?

Never grown the yellow and its my first year with Peach and Black Nagas so it will be a few weeks before I get ripe pods to know for sure but will keep you up to date on this. Ghost pepper leaves do seem to be lighter green with a different shape then my Trinidad collection. Reapers though seem to have darker leaves with purple stems and can be spotted easily in the garden .
