Another mystery pepper courtesy of Burpee Carnival Blend Sweet Peppers.

Any ideas? It's taking forever to ripen (compared to my habaneros), goes from light green to pale yellow and finally orange here. The first set of peppers it produced were same shape but larger, and never seemed to progress past a pale yellow – I thought it was Hungarian Wax Pepper. Unfortunately more pictures might of the plant might not be helpful as it was ravaged by aphids – it's the Charlie Brown Christmas Tree of peppers.
